Cutting a release

A release is a tag on the branch that owns the line: <branch> below is main for the current major and release/3.x for 3.x maintenance. Every step runs against that branch, including the docs PR, so a maintenance entry lands in the maintenance branch's own changelog above its newest 3.x entry. The tag triggers Publish fastmcp-slim to PyPI; its success fans out to fastmcp-tasks, fastmcp-remote, and fastmcp, and the fastmcp publish job opens the published-docs PR that makes gofastmcp.com reflect the release. Two hand-maintained docs files mirror every release and must be on the tagged commit, so the docs PR always lands first. PyPI releases are immutable; a bad one gets a follow-up patch, never a re-tag.
