Zulip server release checklist
This document has reminders of things one might forget to do when preparing a new release.
A week before the release
Major releases only (e.g. 4.0):
Upgrade all Python dependencies in
requirementsto latest upstream versions so they can burn in (use
pip list --outdated).
Upgrade all puppet dependencies in
Upgrade all puppet-installed dependencies (e.g. Smokescreen, go, etc) in
Merge draft updates to the changelog with changes since the last release. While doing so, take notes on things that might need follow-up work or documentation before we can happily advertise them in a release blog post.
TODO/compatibilitycomments for whether we can remove any backwards-compatibility code in this release.
Create a burn-down list of issues that need to be fixed before we can release, and make sure all of them are being worked on.
Draft the release blog post (a.k.a. the release notes) in Paper. In it, list the important changes in the release, from most to least notable.
Final release preparation
Update the Paper blog post draft with any new commits.
Download updated translation strings from Transifex and commit them. Use the

Test the new tarball extensively, both new install and upgrade from last release, on Ubuntu 20.04 or 22.04.
Repeat until release is ready.
Send around the Paper blog post draft for review.
Move the blog post draft to Astro:
Use “··· > Export > Markdown” to get a pretty good Markdown conversion, and save it in
src/postswith a filename appropriate for a URL slug.
Add the needed YAML frontmatter.
Move any images into
publicand update their references.
Proofread, especially for formatting.
If the draft post should remain secret until release, avoid using a guessable Git branch name for the pull request (the deployment preview URL is based on the branch name).
Major releases only (e.g. 4.0): Schedule team members to provide extra responsive #production help support following the release.
