All notable changes to the Zulip server are documented in this file.
This section lists notable unreleased changes; it is generally updated in bursts.
These changes likely will not be included in Zulip 1.9, but are scheduled for the next major release.
- Added support for limited-permissions “guest” users.
- Added support for clearing push notifications on Android.
- Redesigned search navbar area to use more attractive input pills.
Unreleased targeting Zulip 1.9¶
This section lists notable unreleased changes that will be included in Zulip 1.9; it is generally updated in bursts.
- Added support for custom profile fields.
- Added support for Debian stretch and Ubuntu bionic.
- Added support for using Google Hangouts as the video chat provider.
- Added support for configuring a private stream so subscribers can access full history, even before they joined the stream.
- Added support for announcement-only streams.
- Adopted docker-zulip to be now the official Docker image for Zulip.
- Added support for using matrix.org as an IRC gateway.
- Added support for configuring email notifications for all messages in a stream (useful for very low-traffic streams/organizations).
- New translations: Ukrainian and others.
- Zulip 1.9 contains a significant database migration that can take several minutes to run. The upgrade process automatically minimizes disruption by running this migration first, before beginning the user-facing downtime. However, if you’d like to watch the downtime phase of the upgrade closely, we recommend running them first manually and as well as the usual trick of doing an apt upgrade first.

Thanks to Suhas Sunil Gaikwad for reporting CVE-2018-9987 and w2w for reporting CVE-2018-9986 and CVE-2018-9990.
1.7.1 – 2017-11-21¶
This is a security release, with a handful of cherry-picked changes since 1.7.0. All Zulip server admins are encouraged to upgrade promptly.
This release includes fixes for the upgrade process, so server admins running a version from before 1.7 should upgrade directly to 1.7.1.
- CVE-2017-0910: On a server with multiple realms, a vulnerability in the invitation system allowed an authorized user of one realm to create an account on any other realm.
- The Korean translation is now complete, a huge advance from almost nothing in 1.7.0. The French translation is now nearly complete, and several other languages have smaller updates.
- The installer now sets LC_ALL to a known locale, working around an issue where some dependencies fail to install in some locales.
- We fixed a bug in the script that runs after upgrading Zulip (so the fix applies when upgrading to this version), where the garbage-collection of old deployments sometimes wouldn’t preserve the immediate last deployment.
1.7.0 – 2017-10-25¶
- We’ve completely redesigned our onboarding process to explain Zulip, and especially topics, to new users.
- We’ve built a beautiful new emoji picker with categories, a showcase, and much better data. Note the clean, underscore-free display!
- The emails sent by Zulip are more consistent, readable, and visually interesting.
- Chinese (Simplified) and Japanese join Spanish, German, and Czech in having the user interface fully translated, in addition to partial translations for many other languages. We also fixed many small issues where strings weren’t tagged for translation.
- Many pages have been redesigned to be easier to use and visually cleaner, including the settings pages and the user documentation at /help, /integrations, and /apps.
Mobile and Desktop support
- Zulip Server 1.7 adds several new APIs that are critical for mobile app performance and that let the app track unread messages. If you’re using the mobile apps at all (iOS or Android), you will definitely want to upgrade to Zulip 1.7.
- The iOS and Android apps can receive push notifications (configurable, naturally) for events like PMs and @-mentions. While Zulip Server 1.6 has basic support for these, 1.7 brings a new, clearer format to notifications, and gives each user more options for finer-grained control.
- The new Electron desktop app is out of beta and replaces our legacy desktop apps.
Backend and scaling
- Zulip now runs exclusively on Python 3. This is the culmination of an 18-month migration effort. We are very excited about this!
- We’ve added an automatic “soft deactivation” process, which dramatically improves performance for organizations with a large number of inactive users, without any impact on those users’ experience if they later come back.
- Zulip’s performance at scale has improved significantly. Performance now scales primarily with number of active users (not total users). As an example, chat.zulip.org serves 400 monthly active users and about 3500 total users, on one VM with just 8GB of RAM and a CPU consistently over 90% idle.
Zulip 1.7 contains some significant database migrations that can take several minutes to run. The upgrade process automatically minimizes disruption by running these first, before beginning the user-facing downtime. However, if you’d like to watch the downtime phase of the upgrade closely, we recommend running them first manually and as well as the usual trick of doing an apt upgrade first.
We’ve removed support for an uncommon legacy deployment model where a Zulip server served multiple organizations on the same domain. Installs with multiple organizations now require each organization to have its own subdomain.
This change should have no effect for the vast majority of Zulip servers that only have one organization. If you manage a server that hosts multiple organizations, you’ll want to read our guide on multiple organizations.
We simplified the configuration for our password strength checker to be much more intuitive. If you were using the
PASSWORD_MIN_ZXCVBN_QUALITYsetting, it has been replaced by the more intuitive
