Blueprint branch releases

Blueprints can now publish independent releases from multiple Git branches. Declare a branches list in your blueprint spec, and each push to a declared branch produces a release on its own release channel. See the branch deployments docs for the full configuration reference.

Branch tracking on blueprint installations

Pin a blueprint installation to a branch by setting the branch field instead of releaseChannel. The installation resolves to the matching branch channel automatically and upgrades whenever a new commit lands on that branch.
