Zulip is at version 2.1 and it is awesome. Zulip is a chat and workplace communication tool you can use to coordinate and discuss work-related tasks. If you are already using Slack, HipChat, Mattermost or Gitter, it’s possible to import data from those tools straight into Zulip so migrating is a piece of cake.
If you have a large organization, Zulip 2.1 lets you use any PostgreSQL database for full-text search so you can search through the channel and topic discussions chat logs using Amazon RDS or your own self-hosted PostgreSQL instance.
Big news for enterprises is that Zulip 2.1 supports SAML authentication and there are LDAP fixes that have been included in the release.
And of course there are more improvements to integrations such as Buildbot, Redmine and more.
