Enhanced Permission System with Source and Behavior Tracking#

What changed: Permission rules now include metadata about their origin and behavior type Previous behavior: Rules were simple objects with just type and rules array New behavior: Rules now track their source (session/localSettings/cliArg) and behavior (allow/deny) Impact: Better debugging of permission issues and understanding of where rules originate from

New Permission Management Operations#

What changed: Added ability to remove and replace permission rules dynamically Previous behavior: Could only add rules and directories to permissions New behavior: Three new operations available: removeRules, removeDirectories, and replaceRules Impact: More flexible permission management during runtime, allowing selective removal of rules from specific sources

Improved Session Notes Extraction#

What changed: Better filtering of system-generated content from session notes Previous behavior: Basic exclusion of note-taking instructions New behavior: Now excludes system prompts, claude.md entries, and past session summaries Impact: Cleaner session notes that only capture actual user conversations

Permission Update Logging#

What changed: Added detailed logging for all permission operations Previous behavior: No logging of permission changes New behavior: Every permission update is logged with details about rules, sources, and behaviors Impact: Easier troubleshooting of permission-related issues with clear audit trail

v1.0.87 does not have its own entry in Anthropic’s official changelog, because prerelease builds are often folded into a neighbouring release. Browse the full changelog for the closest official notes. Everything else on this page came out of the bundle instead, which is why the two lists don't match.
