Zulip 12.0 ships 5,500 commits since August 2025, adding E2E push notification encryption, a major Docker overhaul, and configurable image previews.
Key Takeaways
Mobile push notifications now use end-to-end encryption from Zulip server to device; self-hosted orgs get full data control with no relay trust required.
Docker, Docker Compose, and Helm deployments get a ground-up overhaul resolving nearly all open issues, plus a new OCI-available Helm chart with schema.
Zulip’s maintainers report Claude Code now produces near-merge-ready PRs starting from just a linked issue or Zulip conversation, with quality matching core-team output.
AI slop from GSoC applicants overwhelmed the review queue October through February; hundreds of LLM-generated PRs received, virtually none merged, new AI use policy and bans enforced.
Demo organizations now require no email, auto-delete after 30 days; 160 contributors added since 11.0, bringing the project to 1,680 total code contributors.
