What has changed since

An entry is only as true as the day it was written.

Flags move on the server after a release ships. Anthropic's own notes land days later and their documentation later still. Sometimes an entry turns out to be wrong and gets corrected by hand. All of that is recorded against the entry it happened to, and this is the whole of it in the order it happened.

Nothing here replaces an entry. Every line links to the page its release published, still saying what that release said, because a correction is added and dated rather than swapped in.

v2.1.309--setting-sources Documentation arrivedAnthropic's documentation has since written up --setting-sources, on Claude Code changelog.

the line in the docs

* Improved session auto-titles: a session that starts with a skill or a prompt-based command such as `/security-review` now gets a title from it instead of staying untitled
v2.1.311/design-sync Documentation arrivedAnthropic's documentation has since written up /design-sync, on Claude Code changelog.
the line in the docs

* Improved the `/design-sync` upload prompt to show the folder, the project and the files it will upload or delete
