Bifrost follows standard semantic versioning (MAJOR.MINOR.PATCH). The cadence below describes when each release type ships, what it typically contains, and how to decide whether you need to upgrade.

​
Cadence at a glance

​
Patch releases

Patch versions ship every 2 - 3 days. A patch may include:
  • Bug fixes
  • CVE / security patches
  • Small feature previews (gated behind config flags where applicable)
Each patch is independently installable, but every patch is also rolled into the next minor release, so deployments that follow the 3 - 4 week cadence pick them all up automatically.

​
Minor releases

A minor version is cut once every 3 - 4 weeks. It consolidates every patch released since the previous minor, alongside any new non-breaking features that landed in that window. Picking up the latest minor gives you everything from the intervening patches in a single deploy.

​
Major releases

Major versions are reserved for breaking changes or major architectural cuts. Each major release is paired with a migration guide listing every breaking change with before/after examples and a step-by-step checklist.

​
Do you need to upgrade every release?

No. Patch and minor releases are cumulative, so skipping intermediate versions is safe - you can stay on whichever release line matches your deployment cadence. Upgrade immediately only when the release notes explicitly say so. That signal is reserved for high-severity CVEs, data-correctness fixes, or production-impacting regressions. Everything else can ride the regular cadence.
