Update changelog for Zulip 1.4.3 release.

streams: Fix autosubscribe security bug (CVE-2017-0881).
A bug in Zulip's implementation of the "stream exists" endpoint meant that any user of a Zulip server could subscribe to an invite-only stream without needing to be invited by using the "autosubscribe" argument. Thanks to Rafid Aslam for discovering this issue.

-# Quick format and style primer:
-#
-#  * If a pattern is meant only for a specific location, it should have a
-#    leading slash, like `/staticfiles.json`.
-#    * In principle any non-trailing slash (like `zproject/dev-secrets.conf`)
-#      will do, but this makes a confusing pattern.  Adding a leading slash
-#      is clearer.
-#
-#  * Patterns like `.vscode/` without slashes, or with only a trailing slash,
-#    match in any subdirectory.
-#
-#  * Subdirectories with several internal things to ignore get their own
-#    `.gitignore` files.
-#
-#  * Comments must be on their own line.  (Otherwise they don't work.)

-# Zulip Code of Conduct
-
-Like the technical community as a whole, the Zulip team and community is
-made up of a mixture of professionals and volunteers from all over the
-world, working on every aspect of the mission, including mentorship,
-teaching, and connecting people.
-
-Diversity is one of our huge strengths, but it can also lead to
-communication issues and unhappiness. To that end, we have a few ground
-rules that we ask people to adhere to. This code applies equally to
-founders, mentors, and those seeking help and guidance.
-
-This isn't an exhaustive list of things that you can't do. Rather, take it
-in the spirit in which it's intended --- a guide to make it easier to enrich
-all of us and the technical communities in which we participate.
-
-## Expected Behavior
-
-The following behaviors are expected and requested of all community members:
-
-* Participate. In doing so, you contribute to the health and longevity of
-  the community.
-* Exercise consideration and respect in your speech and actions.
-* Attempt collaboration before conflict. Assume good faith.
-* Refrain from demeaning, discriminatory, or harassing behavior and speech.
-* Take action or alert community leaders if you notice a dangerous
-  situation, someone in distress, or violations of this code, even if they
-  seem inconsequential.
-* Community event venues may be shared with members of the public; be
-  respectful to all patrons of these locations.
-
-## Unacceptable Behavior
-
-The following behaviors are considered harassment and are unacceptable
-within the Zulip community:
-
-* Jokes or derogatory language that singles out members of any race,
-  ethnicity, culture, national origin, color, immigration status, social and
-  economic class, educational level, language proficiency, sex, sexual
-  orientation, gender identity and expression, age, size, family status,
-  political belief, religion, and mental and physical ability.
-* Violence, threats of violence, or violent language directed against
-  another person.
-* Disseminating or threatening to disseminate another person's personal
-  information.
-* Personal insults of any sort.
-* Posting or displaying sexually explicit or violent material.
-* Inappropriate photography or recording.
-* Deliberate intimidation, stalking, or following (online or in person).
-* Unwelcome sexual attention. This includes sexualized comments or jokes,
-  inappropriate touching or groping, and unwelcomed sexual advances.
-* Sustained disruption of community events, including talks and
-  presentations.
-* Advocating for, or encouraging, any of the behaviors above.
-
-## Reporting and Enforcement
-
-Harassment and other code of conduct violations reduce the value of the
-community for everyone. If someone makes you or anyone else feel unsafe or
-unwelcome, please report it to the community organizers at
-zulip-code-of-conduct@googlegroups.com as soon as possible. You can make a
-report either personally or anonymously.
-
-If a community member engages in unacceptable behavior, the community
-organizers may take any action they deem appropriate, up to and including a
-temporary ban or permanent expulsion from the community without warning (and
-without refund in the case of a paid event).
-
-If someone outside the development community (e.g. a user of the Zulip
-software) engages in unacceptable behavior that affects someone in the
-community, we still want to know. Even if we don't have direct control over
-the violator, the community organizers can still support the people
-affected, reduce the chance of a similar violation in the future, and take
-any direct action we can.
-
-The nature of reporting means it can only help after the fact. If you see
-something you can do while a violation is happening, do it. A lot of the
-harms of harassment and other violations can be mitigated by the victim
-knowing that the other people present are on their side.
-
-All reports will be kept confidential. In some cases, we may determine that a
-public statement will need to be made. In such cases, the identities of all
-victims and reporters will remain confidential unless those individuals
-instruct us otherwise.
-
-## Scope
-
-We expect all community participants (contributors, paid or otherwise,
-sponsors, and other guests) to abide by this Code of Conduct in all
-community venues, online and in-person, as well as in all private
-communications pertaining to community business.
-
-This Code of Conduct and its related procedures also applies to unacceptable
-behavior occurring outside the scope of community activities when such
-behavior has the potential to adversely affect the safety and well-being of
-community members.
-
-## License and Attribution
-
-This Code of Conduct is adapted from the
-[Citizen Code of Conduct](http://citizencodeofconduct.org/) and the
-[Django Code of Conduct](https://www.djangoproject.com/conduct/), and is

-# Contributing to Zulip
-
-Welcome to the Zulip community!
-
-## Community
-
-The
-[Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html)
-is the primary communication forum for the Zulip community. It is a good
-place to start whether you have a question, are a new contributor, are a new
-user, or anything else. Make sure to read the
-[community norms](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html#community-norms)
-before posting. The Zulip community is also governed by a
-[code of conduct](https://zulip.readthedocs.io/en/latest/code-of-conduct.html).
-
-You can subscribe to zulip-devel-announce@googlegroups.com or our
-[Twitter](https://twitter.com/zulip) account for a lower traffic (~1
-email/month) way to hear about things like mentorship opportunities with Google
-Code-in, in-person sprints at conferences, and other opportunities to
-contribute.
-
-## Ways to contribute
-
-To make a code or documentation contribution, read our
-[step-by-step guide](#your-first-codebase-contribution) to getting
-started with the Zulip codebase. A small sample of the type of work that
-needs doing:
-* Bug squashing and feature development on our Python/Django
-  [backend](https://github.com/zulip/zulip), web
-  [frontend](https://github.com/zulip/zulip), React Native
-  [mobile app](https://github.com/zulip/zulip-mobile), or Electron
-  [desktop app](https://github.com/zulip/zulip-desktop).
-* Building out our
-  [Python API and bots](https://github.com/zulip/python-zulip-api) framework.
-* [Writing an integration](https://zulipchat.com/api/integrations-overview).
-* Improving our [user](https://zulipchat.com/help/) or
-  [developer](https://zulip.readthedocs.io/en/latest/) documentation.
-* [Reviewing code](https://zulip.readthedocs.io/en/latest/contributing/code-reviewing.html)
-  and manually testing pull requests.
-
-**Non-code contributions**: Some of the most valuable ways to contribute
-don't require touching the codebase at all. We list a few of them below:
-
-* [Reporting issues](#reporting-issues), including both feature requests and
-  bug reports.
-* [Giving feedback](#user-feedback) if you are evaluating or using Zulip.
-* [Translating](https://zulip.readthedocs.io/en/latest/translating/translating.html)
-  Zulip.
-* [Outreach](#zulip-outreach): Star us on GitHub, upvote us
-  on product comparison sites, or write for [the Zulip blog](http://blog.zulip.org/).
-
-## Your first (codebase) contribution
-
-This section has a step by step guide to starting as a Zulip codebase
-contributor. It's long, but don't worry about doing all the steps perfectly;
-no one gets it right the first time, and there are a lot of people available
-to help.
-* First, make an account on the
-  [Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html),
-  paying special attention to the community norms. If you'd like, introduce
-  yourself in
-  [#new members](https://chat.zulip.org/#narrow/stream/95-new-members), using
-  your name as the topic. Bonus: tell us about your first impressions of
-  Zulip, and anything that felt confusing/broken as you started using the
-  product.
-* Read [What makes a great Zulip contributor](#what-makes-a-great-zulip-contributor).
-* [Install the development environment](https://zulip.readthedocs.io/en/latest/development/overview.html),
-  getting help in
-  [#development help](https://chat.zulip.org/#narrow/stream/49-development-help)
-  if you run into any troubles.
-* Read the
-  [Zulip guide to Git](https://zulip.readthedocs.io/en/latest/git/index.html)
-  and do the Git tutorial (coming soon) if you are unfamiliar with
-  Git, getting help in
-  [#git help](https://chat.zulip.org/#narrow/stream/44-git-help) if
-  you run into any troubles.  Be sure to check out the
-  [extremely useful Zulip-specific tools page](https://zulip.readthedocs.io/en/latest/git/zulip-tools.html).
-* Sign the
-  [Dropbox Contributor License Agreement](https://opensource.dropbox.com/cla/).
-
-### Picking an issue
-
-Now, you're ready to pick your first issue! There are hundreds of open issues
-in the main codebase alone. This section will help you find an issue to work
-on.
-
-* If you're interested in
-  [mobile](https://github.com/zulip/zulip-mobile/issues?q=is%3Aopen+is%3Aissue),
-  [desktop](https://github.com/zulip/zulip-desktop/issues?q=is%3Aopen+is%3Aissue),
-  or
-  [bots](https://github.com/zulip/python-zulip-api/issues?q=is%3Aopen+is%3Aissue)
-  development, check the respective links for open issues, or post in
-  [#mobile](https://chat.zulip.org/#narrow/stream/48-mobile),
-  [#desktop](https://chat.zulip.org/#narrow/stream/16-desktop), or
-  [#integration](https://chat.zulip.org/#narrow/stream/127-integrations).
-* For the main server and web repository, we recommend browsing
-  recently opened issues to look for issues you are confident you can
-  fix correctly in a way that clearly communicates why your changes
-  are the correct fix.  Our GitHub workflow bot, zulipbot, limits
-  users who have 0 commits merged to claiming a single issue labeled
-  with "good first issue" or "help wanted".
-* We also partition all of our issues in the main repo into areas like
-  admin, compose, emoji, hotkeys, i18n, onboarding, search, etc. Look
-  through our [list of labels](https://github.com/zulip/zulip/labels), and
-  click on some of the `area:` labels to see all the issues related to your
-  areas of interest.
-* If the lists of issues are overwhelming, post in
-  [#new members](https://chat.zulip.org/#narrow/stream/95-new-members) with a
-  bit about your background and interests, and we'll help you out. The most
-  important thing to say is whether you're looking for a backend (Python),
-  frontend (JavaScript and TypeScript), mobile (React Native), desktop (Electron),
-  documentation (English) or visual design (JavaScript/TypeScript + CSS) issue, and a
-  bit about your programming experience and available time.
-
-We also welcome suggestions of features that you feel would be valuable or
-changes that you feel would make Zulip a better open source project. If you
-have a new feature you'd like to add, we recommend you start by posting in
-[#new members](https://chat.zulip.org/#narrow/stream/95-new-members) with the
-feature idea and the problem that you're hoping to solve.
-
-Other notes:
-* For a first pull request, it's better to aim for a smaller contribution
-  than a bigger one. Many first contributions have fewer than 10 lines of
-  changes (not counting changes to tests).
-* The full list of issues explicitly looking for a contributor can be
-  found with the
-  [good first issue](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
-  and
-  [help wanted](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-  labels.  Avoid issues with the "difficult" label unless you
-  understand why it is difficult and are confident you can resolve the
-  issue correctly and completely.  Issues without one of these labels
-  are fair game if Tim has written a clear technical design proposal
-  in the issue, or it is a bug that you can reproduce and you are
-  confident you can fix the issue correctly.
-* For most new contributors, there's a lot to learn while making your first
-  pull request. It's OK if it takes you a while; that's normal! You'll be
-  able to work a lot faster as you build experience.
-
-### Working on an issue
-
-To work on an issue, claim it by adding a comment with `@zulipbot claim` to
-the issue thread. [Zulipbot](https://github.com/zulip/zulipbot) is a GitHub
-workflow bot; it will assign you to the issue and label the issue as "in
-progress". Some additional notes:
-
-* You can only claim issues with the
-  [good first issue](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
-  or
-  [help wanted](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-  labels. Zulipbot will give you an error if you try to claim an issue
-  without one of those labels.
-* You're encouraged to ask questions on how to best implement or debug your
-  changes -- the Zulip maintainers are excited to answer questions to help
-  you stay unblocked and working efficiently. You can ask questions on
-  chat.zulip.org, or on the GitHub issue or pull request.
-* We encourage early pull requests for work in progress. Prefix the title of
-  work in progress pull requests with `[WIP]`, and remove the prefix when
-  you think it might be mergeable and want it to be reviewed.
-* After updating a PR, add a comment to the GitHub thread mentioning that it
-  is ready for another review. GitHub only notifies maintainers of the
-  changes when you post a comment, so if you don't, your PR will likely be
-  neglected by accident!
-
-### And beyond
-
-A great place to look for a second issue is to look for issues with the same
-`area:` label as the last issue you resolved. You'll be able to reuse the
-work you did learning how that part of the codebase works. Also, the path to
-becoming a core developer often involves taking ownership of one of these area
-labels.
-
-## What makes a great Zulip contributor?
-
-Zulip runs a lot of [internship programs](#internship-programs), so we have
-a lot of experience with new contributors. In our experience, these are the
-best predictors of success:
-
-* Posting good questions. This generally means explaining your current
-  understanding, saying what you've done or tried so far, and including
-  tracebacks or other error messages if appropriate.
-* Learning and practicing
-  [Git commit discipline](https://zulip.readthedocs.io/en/latest/contributing/version-control.html#commit-discipline).
-* Submitting carefully tested code. This generally means checking your work
-  through a combination of automated tests and manually clicking around the
-  UI trying to find bugs in your work. See
-  [things to look for](https://zulip.readthedocs.io/en/latest/contributing/code-reviewing.html#things-to-look-for)
-  for additional ideas.
-* Posting
-  [screenshots or GIFs](https://zulip.readthedocs.io/en/latest/tutorials/screenshot-and-gif-software.html)
-  for frontend changes.
-* Being responsive to feedback on pull requests. This means incorporating or
-  responding to all suggested changes, and leaving a note if you won't be
-  able to address things within a few days.
-* Being helpful and friendly on chat.zulip.org.
-
-These are also the main criteria we use to select interns for all of our
-internship programs.
-
-## Reporting issues
-
-If you find an easily reproducible bug and/or are experienced in reporting
-bugs, feel free to just open an issue on the relevant project on GitHub.
-
-If you have a feature request or are not yet sure what the underlying bug
-is, the best place to post issues is
-[#issues](https://chat.zulip.org/#narrow/stream/9-issues) (or
-[#mobile](https://chat.zulip.org/#narrow/stream/48-mobile) or
-[#desktop](https://chat.zulip.org/#narrow/stream/16-desktop)) on the
-[Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html).
-This allows us to interactively figure out what is going on, let you know if
-a similar issue has already been opened, and collect any other information
-we need. Choose a 2-4 word topic that describes the issue, explain the issue
-and how to reproduce it if known, your browser/OS if relevant, and a
-[screenshot or screenGIF](https://zulip.readthedocs.io/en/latest/tutorials/screenshot-and-gif-software.html)
-if appropriate.
-
-**Reporting security issues**. Please do not report security issues
-  publicly, including on public streams on chat.zulip.org. You can email
-  zulip-security@googlegroups.com. We create a CVE for every security issue.
-
-## User feedback
-
-Nearly every feature we develop starts with a user request. If you are part
-of a group that is either using or considering using Zulip, we would love to
-hear about your experience with the product. If you're not sure what to
-write, here are some questions we're always very curious to know the answer
-to:
-
-* Evaluation: What is the process by which your organization chose or will
-  choose a group chat product?
-* Pros and cons: What are the pros and cons of Zulip for your organization,
-  and the pros and cons of other products you are evaluating?
-* Features: What are the features that are most important for your
-  organization? In the best case scenario, what would your chat solution do
-  for you?
-* Onboarding: If you remember it, what was your impression during your first
-  few minutes of using Zulip? What did you notice, and how did you feel? Was
-  there anything that stood out to you as confusing, or broken, or great?
-* Organization: What does your organization do? How big is the organization?
-  A link to your organization's website?
-
-## Internship programs
-
-Zulip runs internship programs with
-[Outreachy](https://www.outreachy.org/),
-[Google Summer of Code (GSoC)](https://developers.google.com/open-source/gsoc/)
-[1], and the
-[MIT Externship program](https://alum.mit.edu/students/NetworkwithAlumni/ExternshipProgram),
-and has in the past taken summer interns from Harvard, MIT, and
-Stanford.
-
-While each third-party program has its own rules and requirements, the
-Zulip community's approaches all of these programs with these ideas in
-mind:
-* We try to make the application process as valuable for the applicant as
-  possible. Expect high quality code reviews, a supportive community, and
-  publicly viewable patches you can link to from your resume, regardless of
-  whether you are selected.
-* To apply, you'll have to submit at least one pull request to a Zulip
-  repository.  Most students accepted to one of our programs have
-  several merged pull requests (including at least one larger PR) by
-  the time of the application deadline.
-* The main criteria we use is quality of your best contributions, and
-  the bullets listed at
-  [What makes a great Zulip contributor](#what-makes-a-great-zulip-contributor).
-  Because we focus on evaluating your best work, it doesn't hurt your
-  application to makes mistakes in your first few PRs as long as your
-  work improves.
-
-Zulip also participates in
-[Google Code-In](https://developers.google.com/open-source/gci/). Our
-selection criteria for Finalists and Grand Prize Winners is the same as our
-selection criteria for interns above.
-
-Most of our interns end up sticking around the project long-term, and many
-quickly become core team members. We hope you apply!
-
-### Google Summer of Code
-
-GSoC is by far the largest of our internship programs (14 students in
-2017; 11 in 2018; 17 in 2019).  While we don't control how many slots
-Google allocates to Zulip, we hope to mentor a similar number of
-students in future summers.
-
-If you're reading this well before the application deadline and want
-to make your application strong, we recommend getting involved in the
-community and fixing issues in Zulip now. Having good contributions
-and building a reputation for doing good work is best way to have a
-strong application.  About half of Zulip's GSoC students for Summer
-2017 had made significant contributions to the project by February
-2017, and about half had not.  Our
-[GSoC project ideas page][gsoc-guide] has lots more details on how
-Zulip does GSoC, as well as project ideas (though the project idea
-list is maintained only during the GSoC application period, so if
-you're looking at some other time of year, the project list is likely
-out-of-date).
-
-We also have in some past years run a Zulip Summer of Code (ZSoC)
-program for students who we didn't have enough slots to accept for
-GSoC but were able to find funding for.  Student expectations are the
-same as with GSoC, and it has no separate application process; your
-GSoC application is your ZSoC application.  If we'd like to select you
-for ZSoC, we'll contact you when the GSoC results are announced.
-
-[gsoc-guide]: https://zulip.readthedocs.io/en/latest/overview/gsoc-ideas.html
-[gsoc-faq]: https://developers.google.com/open-source/gsoc/faq
-
-[1] Formally, [GSoC isn't an internship][gsoc-faq], but it is similar
-enough that we're treating it as such for the purposes of this
-documentation.
-
-## Zulip Outreach
-
-**Upvoting Zulip**. Upvotes and reviews make a big difference in the public
-perception of projects like Zulip. We've collected a few sites below
-where we know Zulip has been discussed. Doing everything in the following
-list typically takes about 15 minutes.
-* Star us on GitHub. There are four main repositories:
-  [server/web](https://github.com/zulip/zulip),
-  [mobile](https://github.com/zulip/zulip-mobile),
-  [desktop](https://github.com/zulip/zulip-desktop), and
-  [Python API](https://github.com/zulip/python-zulip-api).
-* [Follow us](https://twitter.com/zulip) on Twitter.
-
-For both of the following, you'll need to make an account on the site if you

-
-* [Like Zulip](https://alternativeto.net/software/zulip-chat-server/) on
-  AlternativeTo. We recommend upvoting a couple of other products you like
-  as well, both to give back to their community, and since single-upvote
-  accounts are generally given less weight. You can also
-  [upvote Zulip](https://alternativeto.net/software/slack/) on their page
-  for Slack.
-* [Add Zulip to your stack](https://stackshare.io/zulip) on StackShare, star
-  it, and upvote the reasons why people like Zulip that you find most
-  compelling. Again, we recommend adding a few other products that you like
-  as well.
-
-We have a doc with more detailed instructions and a few other sites, if you
-have been using Zulip for a while and want to contribute more.
-
-**Blog posts**. Writing a blog post about your experiences with Zulip, or
-about a technical aspect of Zulip can be a great way to spread the word
-about Zulip.
-
-We also occasionally [publish](http://blog.zulip.org/) longer form
-articles related to Zulip. Our posts typically get tens of thousands
-of views, and we always have good ideas for blog posts that we can
-outline but don't have time to write. If you are an experienced writer
-or copyeditor, send us a portfolio; we'd love to talk!

 # Zulip overview

-Zulip is a powerful, open source group chat application that combines the
-immediacy of real-time chat with the productivity benefits of threaded
-conversations. Zulip is used by open source projects, Fortune 500 companies,
-large standards bodies, and others who need a real-time chat system that
-allows users to easily process hundreds or thousands of messages a day. With
-over 500 contributors merging over 500 commits a month, Zulip is also the
-largest and fastest growing open source group chat project.
+Zulip is a powerful, open source group chat application. Written in
+Python and using the Django framework, Zulip supports both private
+messaging and group chats via conversation streams.

-join us on the
-[Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html)
-and tell us what's up!
+## Community

-You might be interested in:
+There are several places online where folks discuss Zulip.

-* **Contributing code**. Check out our
-  [guide for new contributors](https://zulip.readthedocs.io/en/latest/overview/contributing.html)
-  to get started. Zulip prides itself on maintaining a clean and
-  well-tested codebase, and a stock of hundreds of
-  [beginner-friendly issues][beginner-friendly].
+One of those places is our [public Zulip instance](https://zulip.tabbott.net/).
+You can go through the simple signup process at that link, and then you
+will soon be talking to core Zulip developers and other users.  To get
+help in real time, you will have the best luck finding core developers
+roughly between 16:00 UTC and 23:59 UTC.  Most questions get answered
+within a day.

-* **Contributing non-code**.
-  [Report an issue](https://zulip.readthedocs.io/en/latest/overview/contributing.html#reporting-issue),
-  [translate](https://zulip.readthedocs.io/en/latest/translating/translating.html) Zulip
-  into your language,
-  [write](https://zulip.readthedocs.io/en/latest/overview/contributing.html#zulip-outreach)
-  for the Zulip blog, or
-  [give us feedback](https://zulip.readthedocs.io/en/latest/overview/contributing.html#user-feedback). We
-  would love to hear from you, even if you're just trying the product out.
+We have a [Google mailing list](https://groups.google.com/forum/#!forum/zulip-devel)
+that is currently pretty low traffic.  It is where we do things like
+announce public meetings or major releases.  You can also use it to
+ask questions about features or possible bugs.

-* **Supporting Zulip**. Advocate for your organization to use Zulip, write a
-  review in the mobile app stores, or
-  [upvote Zulip](https://zulip.readthedocs.io/en/latest/overview/contributing.html#zulip-outreach) on
-  product comparison sites.
+Last but not least, we use [GitHub](https://github.com/zulip/zulip) to
+track Zulip-related issues (and store our code, of course).
+Anybody with a Github account should be able to create Issues there
+pertaining to bugs or enhancement requests.  We also use Pull
+Requests as our primary mechanism to receive code contributions.

-* **Checking Zulip out**. The best way to see Zulip in action is to drop by
-  the
-  [Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html). We
-  also recommend reading Zulip for
-  [open source](https://zulipchat.com/for/open-source/), Zulip for
-  [companies](https://zulipchat.com/for/companies/), or Zulip for
-  [working groups and part time communities](https://zulipchat.com/for/working-groups-and-communities/).
+## Installing the Zulip Development environment

-* **Running a Zulip server**. Use a preconfigured [Digital Ocean droplet](https://marketplace.digitalocean.com/apps/zulip),
-  [install Zulip](https://zulip.readthedocs.io/en/stable/production/install.html)
-  directly, or use Zulip's
-  experimental [Docker image](https://zulip.readthedocs.io/en/latest/production/deployment.html#zulip-in-docker).
-  Commercial support is available; see <https://zulipchat.com/plans> for details.
+The Zulip development environment is the recommended option for folks
+interested in trying out Zulip.  This is documented in [the developer
+installation guide][dev-install].

-* **Using Zulip without setting up a server**. <https://zulipchat.com> offers
-  free and commercial hosting.
+## Running Zulip in production

-* **Applying for a Zulip internship**. Zulip runs internship programs with
-  [Outreachy](https://www.outreachy.org/),
-  [Google Summer of Code](https://developers.google.com/open-source/gsoc/),
-  and the
-  [MIT Externship program](https://alum.mit.edu/students/NetworkwithAlumni/ExternshipProgram). Zulip
-  also participates in
-  [Google Code-In](https://developers.google.com/open-source/gci/). More
-  information is available
-  [here](https://zulip.readthedocs.io/en/latest/overview/contributing.html#internship-programs).
+Zulip in production only supports Ubuntu 14.04 right now, but work is
+ongoing on adding support for additional platforms. The installation
+process is documented at https://zulip.org/server.html and in more
+detail in [the
+documentation](https://zulip.readthedocs.io/en/latest/prod-install.html).

-You may also be interested in reading our [blog](http://blog.zulip.org/) or
-following us on [twitter](https://twitter.com/zulip).
-Zulip is distributed under the
-[Apache 2.0](https://github.com/zulip/zulip/blob/master/LICENSE) license.

+
+## How to get involved with contributing to Zulip
+
+First, subscribe to the Zulip [development discussion mailing
+list][gg-devel].
+
+The Zulip project uses a system of labels in our [issue
+tracker][gh-issues] to make it easy to find a project if you don't
+have your own project idea in mind or want to get some experience with
+working on Zulip before embarking on a larger project you have in
+mind:
+
+* [Integrations](https://github.com/zulip/zulip/labels/integrations).
+  Integrate Zulip with another piece of software and contribute it
+  back to the community!  Writing an integration can be a great first
+  contribution.  There's detailed documentation on how to write
+  integrations in [the Zulip integration writing
+  guide](https://zulip.readthedocs.io/en/latest/integration-guide.html).
+
+* [Bite Size](https://github.com/zulip/zulip/labels/bite%20size):
+  Smaller projects that might be a great first contribution.
+
+* [Documentation](https://github.com/zulip/zulip/labels/documentation):
+  The Zulip project loves contributions of new documentation.
+
+* [Help Wanted](https://github.com/zulip/zulip/labels/help%20wanted):
+  A broader list of projects that nobody is currently working on.
+
+* [Platform support](https://github.com/zulip/zulip/labels/Platform%20support):
+  These are open issues about making it possible to install Zulip on a
+  wider range of platforms.
+
+* [Bugs](https://github.com/zulip/zulip/labels/bug): Open bugs.
+
+* [Feature requests](https://github.com/zulip/zulip/labels/enhancement):
+  Browsing this list can be a great way to find feature ideas to
+  implement that other Zulip users are excited about.
+
+* [2016 roadmap milestone](http://zulip.readthedocs.io/en/latest/roadmap.html): The
+  projects that are [priorities for the Zulip project](https://zulip.readthedocs.io/en/latest/roadmap.html).  These are great projects if you're looking to make an impact.
+
+If you're excited about helping with an open issue, just post on the
+conversation thread that you're working on it.  You're encouraged to
+ask questions on how to best implement or debug your changes -- the
+Zulip maintainers are excited to answer questions to help you stay
+unblocked and working efficiently.
+
+We also welcome suggestions of features that you feel would be
+valuable or changes that you feel would make Zulip a better open
+source project, and are happy to support you in adding new features or
+other user experience improvements to Zulip.
+
+If you have a new feature you'd like to add, we recommend you start by
+opening a GitHub issue about the feature idea explaining the problem
+that you're hoping to solve and that you're excited to work on it.  A
+Zulip maintainer will usually reply within a day with feedback on the
+idea, notes on any important issues or concerns, and and often tips on
+how to implement or test it.  Please feel free to ping the thread if
+you don't hear a response from the maintainers -- we try to be very
+responsive so this usually means we missed your message.
+
+For significant changes to the visual design, user experience, data
+model, or architecture, we highly recommend posting a mockup,
+screenshot, or description of what you have in mind to zulip-devel@ to
+get broad feedback before you spend too much time on implementation
+details.
+
+Finally, before implementing a larger feature, we highly recommend
+looking at the new feature tutorial and coding style guidelines on
+ReadTheDocs.
+
+Feedback on how to make this development process more efficient, fun,
+and friendly to new contributors is very welcome!  Just send an email
+to the Zulip Developers list with your thoughts.

+ CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+ LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+ ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS INFORMATION
+ ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE
+ USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED HEREUNDER, AND
+ DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM THE USE OF THIS DOCUMENT
+ OR THE INFORMATION OR WORKS PROVIDED HEREUNDER.
+ .
+ Statement of Purpose
+ .
+ The laws of most jurisdictions throughout the world automatically confer
+ exclusive Copyright and Related Rights (defined below) upon the creator
+ and subsequent owner(s) (each and all, an "owner") of an original work
+ of authorship and/or a database (each, a "Work").
+ .
+ Certain owners wish to permanently relinquish those rights to a Work for
+ the purpose of contributing to a commons of creative, cultural and
+ scientific works ("Commons") that the public can reliably and without
+ fear of later claims of infringement build upon, modify, incorporate in
+ other works, reuse and redistribute as freely as possible in any form
+ whatsoever and for any purposes, including without limitation commercial
+ purposes. These owners may contribute to the Commons to promote the
+ ideal of a free culture and the further production of creative, cultural
+ and scientific works, or to gain reputation or greater distribution for
+ their Work in part through the use and efforts of others.
+ .
+ For these and/or other purposes and motivations, and without any
+ expectation of additional consideration or compensation, the person
+ associating CC0 with a Work (the "Affirmer"), to the extent that he or
+ she is an owner of Copyright and Related Rights in the Work, voluntarily
+ elects to apply CC0 to the Work and publicly distribute the Work under
+ its terms, with knowledge of his or her Copyright and Related Rights in
+ the Work and the meaning and intended legal effect of CC0 on those
+ rights.
+ .
+ 1. Copyright and Related Rights. A Work made available under CC0 may be
+ protected by copyright and related or neighboring rights ("Copyright and
+ Related Rights"). Copyright and Related Rights include, but are not
+ limited to, the following:
+ .
+ i. the right to reproduce, adapt, distribute, perform, display,
+ communicate, and translate a Work;
+ .
+ ii. moral rights retained by the original author(s) and/or performer(s);
+ .
+ iii. publicity and privacy rights pertaining to a person's image or
+ likeness depicted in a Work;
+ .
+ iv. rights protecting against unfair competition in regards to a Work,
+ subject to the limitations in paragraph 4(a), below;
+ .
+ v. rights protecting the extraction, dissemination, use and reuse of
+ data in a Work;
+ .
+ vi. database rights (such as those arising under Directive 96/9/EC of
+ the European Parliament and of the Council of 11 March 1996 on the legal
+ protection of databases, and under any national implementation thereof,
+ including any amended or successor version of such directive); and
+ .
+ vii. other similar, equivalent or corresponding rights throughout the
+ world based on applicable law or treaty, and any national
+ implementations thereof.
+ .
+ 2. Waiver. To the greatest extent permitted by, but not in contravention
+ of, applicable law, Affirmer hereby overtly, fully, permanently,
+ irrevocably and unconditionally waives, abandons, and surrenders all of
+ Affirmer's Copyright and Related Rights and associated claims and causes
+ of action, whether now known or unknown (including existing as well as
+ future claims and causes of action), in the Work (i) in all territories
+ worldwide, (ii) for the maximum duration provided by applicable law or
+ treaty (including future time extensions), (iii) in any current or
+ future medium and for any number of copies, and (iv) for any purpose
+ whatsoever, including without limitation commercial, advertising or
+ promotional purposes (the "Waiver"). Affirmer makes the Waiver for the
+ benefit of each member of the public at large and to the detriment of
+ Affirmer's heirs and successors, fully intending that such Waiver shall
+ not be subject to revocation, rescission, cancellation, termination, or
+ any other legal or equitable action to disrupt the quiet enjoyment of
+ the Work by the public as contemplated by Affirmer's express Statement
+ of Purpose.
+ .
+ 3. Public License Fallback. Should any part of the Waiver for any reason
+ be judged legally invalid or ineffective under applicable law, then the
+ Waiver shall be preserved to the maximum extent permitted taking into
+ account Affirmer's express Statement of Purpose. In addition, to the
+ extent the Waiver is so judged Affirmer hereby grants to each affected
+ person a royalty-free, non transferable, non sublicensable, non
+ exclusive, irrevocable and unconditional license to exercise Affirmer's
+ Copyright and Related Rights in the Work (i) in all territories
+ worldwide, (ii) for the maximum duration provided by applicable law or
+ treaty (including future time extensions), (iii) in any current or
+ future medium and for any number of copies, and (iv) for any purpose
+ whatsoever, including without limitation commercial, advertising or
+ promotional purposes (the "License"). The License shall be deemed
+ effective as of the date CC0 was applied by Affirmer to the Work. Should
+ any part of the License for any reason be judged legally invalid or
+ ineffective under applicable law, such partial invalidity or
+ ineffectiveness shall not invalidate the remainder of the License, and
+ in such case Affirmer hereby affirms that he or she will not (i)
+ exercise any of his or her remaining Copyright and Related Rights in the
+ Work or (ii) assert any associated claims and causes of action with
+ respect to the Work, in either case contrary to Affirmer's express
+ Statement of Purpose.
+ .
+ 4. Limitations and Disclaimers.
+ .
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+ surrendered, licensed or otherwise affected by this document.
+ .
+ b. Affirmer offers the Work as-is and makes no representations or
+ warranties of any kind concerning the Work, express, implied, statutory
+ or otherwise, including without limitation warranties of title,
+ merchantability, fitness for a particular purpose, non infringement, or
+ the absence of latent or other defects, accuracy, or the present or
+ absence of errors, whether or not discoverable, all to the greatest
+ extent permissible under applicable law.
+ .
+ c. Affirmer disclaims responsibility for clearing rights of other
+ persons that may apply to the Work or any use thereof, including without
+ limitation any person's Copyright and Related Rights in the Work.
+ Further, Affirmer disclaims responsibility for obtaining any necessary
+ consents, permissions or other rights required for any use of the Work.
+ .
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+ party to this document and has no duty or obligation with respect to
+ this CC0 or use of the Work.

+ ---------------------------------------------------------------------------
+ .
+ PREAMBLE
+ .
+ The goals of the Open Font License (OFL) are to stimulate worldwide development
+ of collaborative font projects, to support the font creation efforts of academic
+ and linguistic communities, and to provide a free and open framework in which
+ fonts may be shared and improved in partnership with others.
+ .
+ The OFL allows the licensed fonts to be used, studied, modified and redistributed
+ freely as long as they are not sold by themselves. The fonts, including any
+ derivative works, can be bundled, embedded, redistributed and/or sold with any
+ software provided that any reserved names are not used by derivative works. The
+ fonts and derivatives, however, cannot be released under any other type of license.
+ The requirement for fonts to remain under this license does not apply to any
+ document created using the fonts or their derivatives.
+ .
+ DEFINITIONS
+ .

+ statement(s).
+ .
+ "Original Version" refers to the collection of Font Software components as

+ 1) Neither the Font Software nor any of its individual components, in Original or
+ Modified Versions, may be sold by itself.

+ 2) Original or Modified Versions of the Font Software may be bundled, redistributed
+ and/or sold with any software, provided that each copy contains the above copyright
+ notice and this license. These can be included either as stand-alone text files,
+ human-readable headers or in the appropriate machine-readable metadata fields within
+ text or binary files as long as those fields can be easily viewed by the user.
+ .
+ 3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless
+ explicit written permission is granted by the corresponding Copyright Holder. This
+ restriction only applies to the primary font name as presented to the users.
+ .
+ 4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall

+#### Dependencies
+
+The [Zulip API](https://zulip.com/api) Python bindings require the
+following Python libraries:
+
+* simplejson
+* requests (version >= 0.12.1)
+
+
+#### Installing
+
+This package uses distutils, so you can just run:
+
+    python setup.py install
+
+#### Using the API
+
+For now, the only fully supported API operation is sending a message.
+The other API queries work, but are under active development, so
+please make sure we know you're using them so that we can notify you
+as we make any changes to them.
+
+The easiest way to use these API bindings is to base your tools off
+of the example tools under examples/ in this distribution.
+
+If you place your API key in the config file `~/.zuliprc` the Python
+API bindings will automatically read it in. The format of the config
+file is as follows:
+
+    [api]
+    key=<api key from the web interface>
+    email=<your email address>
+    site=<your Zulip server's URI>
+    insecure=<true or false, true means do not verify the server certificate>
+    cert_bundle=<path to a file containing CA or server certificates to trust>
+
+If omitted, these settings have the following defaults:
+
+    site=https://api.zulip.com
+    insecure=false
+    cert_bundle=<the default CA bundle trusted by Python>
+
+Alternatively, you may explicitly use "--user" and "--api-key" in our
+examples, which is especially useful if you are running several bots
+which share a home directory.
+
+The command line equivalents for other configuration options are:
+
+    --site=<your Zulip server's URI>
+    --insecure
+    --cert-bundle=<file>
+
+You can obtain your Zulip API key, create bots, and manage bots all
+from your Zulip [settings page](https://zulip.com/#settings).
+
+A typical simple bot sending API messages will look as follows:
+
+At the top of the file:
+
+    # Make sure the Zulip API distribution's root directory is in sys.path, then:
+    import zulip
+    zulip_client = zulip.Client(email="your-bot@example.com", client="MyTestClient/0.1")
+
+When you want to send a message:
+
+    message = {
+      "type": "stream",
+      "to": ["support"],
+      "subject": "your subject",
+      "content": "your content",
+    }
+    zulip_client.send_message(message)
+
+Additional examples:
+
+    client.send_message({'type': 'stream', 'content': 'Zulip rules!',
+                         'subject': 'feedback', 'to': ['support']})
+    client.send_message({'type': 'private', 'content': 'Zulip rules!',
+                         'to': ['user1@example.com', 'user2@example.com']})
+
+send_message() returns a dict guaranteed to contain the following
+keys: msg, result.  For successful calls, result will be "success" and
+msg will be the empty string.  On error, result will be "error" and
+msg will describe what went wrong.
+
+#### Logging
+The Zulip API comes with a ZulipStream class which can be used with the
+logging module:
+
+```
+import zulip
+import logging
+stream = zulip.ZulipStream(type="stream", to=["support"], subject="your subject")
+logger = logging.getLogger("your_logger")
+logger.addHandler(logging.StreamHandler(stream))
+logger.setLevel(logging.DEBUG)
+logger.info("This is an INFO test.")
+logger.debug("This is a DEBUG test.")
+logger.warn("This is a WARN test.")
+logger.error("This is a ERROR test.")
+```
+
+#### Sending messages
+
+You can use the included `zulip-send` script to send messages via the
+API directly from existing scripts.
+
+    zulip-send hamlet@example.com cordelia@example.com -m \
+        "Conscience doth make cowards of us all."
+
+Alternatively, if you don't want to use your ~/.zuliprc file:
+
+    zulip-send --user shakespeare-bot@example.com \
+        --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5 \
+        hamlet@example.com cordelia@example.com -m \
+        "Conscience doth make cowards of us all."
+
+#### Working with an untrusted server certificate
+
+If your server has either a self-signed certificate, or a certificate signed
+by a CA that you don't wish to globally trust then by default the API will
+fail with an SSL verification error.
+
+You can add `insecure=true` to your .zuliprc file.
+
+    [api]
+    site=https://zulip.example.com
+    insecure=true
+
+This disables verification of the server certificate, so connections are
+encrypted but unauthenticated. This is not secure, but may be good enough
+for a development environment.
+
+
+You can explicitly trust the server certificate using `cert_bundle=<filename>`
+in your .zuliprc file.
+
+    [api]
+    site=https://zulip.example.com
+    cert_bundle=/home/bots/certs/zulip.example.com.crt
+
+You can also explicitly trust a different set of Certificate Authorities from
+the default bundle that is trusted by Python. For example to trust a company
+internal CA.
+
+    [api]
+    site=https://zulip.example.com
+    cert_bundle=/home/bots/certs/example.com.ca-bundle
+
+Save the server certificate (or the CA certificate) in its own file,
+converting to PEM format first if necessary.
+Verify that the certificate you have saved is the same as the one on the
+server.
+
+The `cert_bundle` option trusts the server / CA certificate only for
+interaction with the zulip site, and is relatively secure.
+
+Note that a certificate bundle is merely one or more certificates combined
+into a single file.

+
+This bot requires the feedparser module.
+
+To use this script:
+
+1. Create an RSS feed file containing 1 feed URL per line (default feed
+   file location: ~/.cache/zulip-rss/rss-feeds)
+2. Subscribe to the stream that will receive RSS updates (default stream: rss)
+3. create a ~/.zuliprc as described on https://zulip.com/api#api_keys
+4. Test the script by running it manually, like this:
+
+/usr/local/share/zulip/integrations/rss/rss-bot
+
+You can customize the location on the feed file and recipient stream, e.g.:
+
+/usr/local/share/zulip/integrations/rss/rss-bot --feed-file=/path/to/my-feeds --stream=my-rss-stream
+
+4. Configure a crontab entry for this script. A sample crontab entry for
+processing feeds stored in the default location and sending to the default
+stream every 5 minutes is:
+

Author	SHA1	Message	Date
Tim Abbott	a063dd3b26	Update changelog for Zulip 1.4.3 release.	2017-01-29 15:09:02 -08:00
Tim Abbott	1cdd451d70	streams: Fix autosubscribe security bug (CVE-2017-0881). A bug in Zulip's implementation of the "stream exists" endpoint meant that any user of a Zulip server could subscribe to an invite-only stream without needing to be invited by using the "autosubscribe" argument. Thanks to Rafid Aslam for discovering this issue.	2017-01-29 15:09:02 -08:00
Tim Abbott	8cc7642cdd	Update changelog for Zulip 1.4.1 and 1.4.2 releases.	2016-09-27 20:09:20 -07:00
Tim Abbott	6883c916af	Upgrade Django to 1.8.15 with Zulip patches.	2016-09-27 20:09:20 -07:00
Tim Abbott	978a568c0f	puppet: Fix buggy logrotate configuration.	2016-09-27 20:01:17 -07:00
Steve Howell	f6975f9334	Upgrade: revert change to default LOCAL_UPLOADS_DIR in prod settings. The main purpose of the "var" convention is to make it easy to write stuff inside of our git repo when running a dev instance, and then "var" gets excluded from checkins. For production, that's not as much of a concern. For upgrades we don't want to be changing the directory around and confusing matters, especially with the extra moving part of nginx configs (which have their own issues in terms of being overwritten by accident when admins go to S3).	2016-09-02 12:30:29 -07:00
Christie Koehler	0120ff5612	upgrade: Create prod_settings symlink in step 2 if it doesn't exist. Between releases 1.3.13 and 1.4.0, local_settings.py was renamed to prod_settings.py. The upgrade scripts were adjusted to reflect this name change. But because the first part of the upgrade script is run with the currently installed version's code, the symlink to /etc/zulip/settings.py is created with the old name. This was causing upgrade-zulip-stage-2 to fail. Now upgrade-zulip-stage-2 creates the symlink at zproject/prod_settings.py if it doesn't already exist. Fixes #1731.	2016-09-01 21:17:11 -07:00
