Release Tips

Changelog Checklist

  • Features
    • State benefits first.
    • Order features based on benefit for end users.
    • Include links to docs where appropriate.
  • Bugs
    • Check/test if the issue was in previous server version.
  • All sections
    • Check that all sections are written and formatted the same way as in previous Changelogs.
  • API/Websocket/Database
    • Work with Dev Ops on this section.
  • Next version
    • If the Changelog mentions items regarding upcoming versions, move them to the bottom of the Changelog.

Ways to Meet Deadlines

  • Post a list of dates for next release at or soon after T-0 and ping all of the teams.
  • For features and bugs, start pinging early enough before due dates and make public posts.
  • When pinging people, provide a clear due date and give a reason for the due date (e.g., Code Complete on Monday).
  • Ask if people need any help or have any questions.


  • Post a reminder at T-12 for translators about the release translations due date, e.g.,
  • Monitor progress of translations at and ping language maintainers a few days before due date if they’re not getting to 100%.
  • Ask Elias to hold on submitting final translations PR if some translators need more time, or ask him to submit a new one if a translations PR was already submitted.
  • Target date for final translations PR is T-5, but T-3 is acceptable.

Ways That Features/Bugs Guidelines are Currently Enforced

  • Features guidelines:
    • Sometimes features are merged after T-12.
    • Start to ping people already at T-15 or earlier for feature PRs that are still open.
  • Bugs guidelines:
    • Need to focus on fixing only S1 and S2 bugs after T-5 to avoid missing T-2 deadline for cutting the final.

Ways to Ensure Features are Tested for HA/Mobile/Scale

  • Mobile: Added a release checklist item for QAs for T-11.
  • HA: Test server available.
  • Scale: Via loadtests.

Release Marketing

  • Blog post:
    • Follow guidelines.
    • Audience: end-users, admin/tech.
    • Include CTAs and avoid including external links unless they direct to Mattermost website or documentation.
    • Give release outline for all PMs and Rich before giving to Justin.
  • Email:
    • Check that the link on the email banner is correct.
