Sub-agents can now spawn their own sub-agents (up to 5 levels deep)
- Amazon Bedrock now reads the AWS region from `~/.aws` config files when `AWS_REGION` isn't set, matching AWS SDK precedence; `/status` shows where the region came from
- Added a search bar when browsing a marketplace's plugins in `/plugin`
- Added `model` attribute to the `claude_code.lines_of_code.count` OTEL metric
- Fixed sessions using 1M context without usage credits getting permanently stuck — the session now automatically compacts back under the standard context limit
- +26 more changes
