1.Added support for organization default models — admins set it in the org console; it shows as "Org default" (or "Role default") in /model when you haven't picked one yourself

1.Added CLAUDECODEDISABLEMOUSECLICKS to disable mouse click/drag/hover in fullscreen mode while keeping wheel scroll

1.The stream-stall hint now reads "Waiting for API response · will retry in …" instead of "No response from API · Retrying in …", and triggers after 20s of silence instead of 10s

1.Improved auto mode safety: destructive git commands (git reset --hard, git checkout -- ., git clean -fd, git stash drop) are now blocked when you didn't ask to discard local work, git commit --amend is blocked when the commit wasn't made by the agent this session, and terraform destroy/pulumi destroy/cdk destroy are blocked unless you asked for the specific stack

1.Added wheelScrollAccelerationEnabled setting to disable mouse-wheel scroll acceleration in fullscreen mode

1.Added `enforceAvailableModels` managed setting — when enabled, the `availableModels` allowlist also constrains the Default model (a Default that would resolve to a disallowed model now falls back to the first allowed model), and user or project settings can no longer widen a managed `availableModels` list

1.Sub-agents can now spawn their own sub-agents (up to 5 levels deep)

1.Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Fable’s capabilities exceed those of any model we’ve ever made generally available. Update to version 2.1.170 for access. https://www.anthropic.com/news/claude-fable-5-mythos-5

1.Sub-agents can now spawn their own sub-agents (up to 5 levels deep)

1.`claude agents --json` now includes `waitingFor` showing what a waiting session is blocked on (e.g. permission prompt)

1.Edit no longer requires a separate Read after viewing a file with `grep`: single-file `grep`/`egrep`/`fgrep` commands now satisfy the read-before-edit check

1.`OTEL_RESOURCE_ATTRIBUTES` values are now included as labels on metric datapoints, so you can slice usage metrics by custom dimensions like team or repo
