Release process

Impact: none, no production release yet

Changelog:

• announce new Percona release support strategy in our release
• provide both percona80 (LTS) and percona83 (Innovation) roles
• drop percona81 support

PR release workflow (internal)

• PR has internal ticket
• internal issue ID (PL-…) part of branch name
• internal issue ID mentioned in PR description text
• ticket is on Platform agile board
• ticket state set to Pull request ready
• if ticket is more urgent than within the next few days, directly contact a member of the Platform team

Design notes

• Provide a feature toggle if the change might need to be adjusted/reverted quickly depending on context. Consider whether the default should be on or off. Example: rate limiting.
  • no defaults involved
• All customer-facing features and (NixOS) options need to be discoverable from documentation. Add or update relevant documentation such that hosted and guided customers can understand it as well.

Security implications

• Security requirements defined? (WHERE)
  • pull in updated packages to receive bug and security fixes
  • must not introduce known regressions
  • new package releases need to be covered by tests as well
  • announce version maintenance schedule for Percona
• Security requirements tested? (EVIDENCE)
  • updated docs, built and manually checked the result
  • automated nixos tests need to pass
  • adjusted version number for updated nginx
  • added tests for percona83
