Change Stack shipped as a new code review interface that reorganizes pull requests from a flat file list into a guided, layer-by-layer walkthrough.1
Reviewing AI-authored PRs got a dedicated surface. Change Stack groups a diff into cohorts and layers, each with a range-specific summary and inline diagrams — sequence diagrams for new call flows, ERDs for data model changes.2 Code Peek landed shortly after: click any variable, function, or type name to look up its definition and usages via GitHub code search without leaving the review.3 A Semantic diff view (alongside Unified and Split) groups related code movement and token-level changes.4 Change Stack is in early access on all plans and moving to Pro+.
The CLI gained diagnostics and agent-pipeline improvements. coderabbit doctor checks local setup and surfaces configuration or connectivity issues before a review runs.5 Browser-based sign-in now handles organization selection in one step (v0.5.0). CLI v0.5.2 added coderabbit review findings to replay locally cached results, per-severity breakdowns in plain-text output, and heartbeat events during long reviews in agent mode.6
Slack Agent automations can now trigger on external webhook events. Datadog, PagerDuty, and Pylon are natively supported; any other service connects via a custom webhook with payload field and event-type matching.7 Message-triggered automations also landed, letting automations react to new top-level channel messages.8 An Automation admin role was added for delegated automation management without full workspace-admin access.9
Enterprise teams on private GitHub Enterprise Server can connect without inbound firewall changes. The Reverse Tunnel Connector dials out over WSS to a CodeRabbit-managed gateway.10
GitLab project Owners and Maintainers can now install from the Repositories page without top-level group Owner access.11 Microsoft Presidio Analyzer (PII detection) is now opt-in via reviews.tools.presidio.enabled.12
