Is 'Bug Fixes and Reliability Improvements' Even a Changelog?
Claude Code 2.1.220 is a maintenance release described only as bug fixes and reliability improvements, with no new features listed.
What it is
Claude Code 2.1.220 is the release immediately following 2.1.219's Opus 5 default and strict allowlist changes.
What it does
The release notes list only "bug fixes and reliability improvements" with no itemized changes, unusually terse compared to the detailed changelogs of recent point releases.
Why it matters
It's worth flagging mainly so users on 2.1.219 know an update exists, even though there's nothing specific to act on beyond upgrading.
How to use it
Update via your normal Claude Code update mechanism; no configuration changes are needed.
Claude Code 2.1.218 Moves /code-review to a Background Subagent

Claude Code 2.1.217 Adds Emoji Autocomplete and Fixes an MCP Memory Leak
Claude Code 2.1.217 adds emoji shortcode autocomplete, warns when transcript writes fail instead of losing sessions silently, and fixes a memory leak from truncated MCP tool outputs.
Claude Code 2.1.215 makes /verify and /code-review opt-in again
Claude Code 2.1.215 stops automatically invoking the /verify and /code-review skills, requiring users to run them explicitly with the /verify or /code-review commands.
