+
+## Highlights
+
+- **Getting started checklist** — A new checklist in the sidebar helps users complete initial setup. Its visibility can be controlled in settings.
+- **Workspace paths in Files** — The Files view now shows the workspace path, making it easier to identify the folder currently being explored.
+- **Script-bundle automation installs** — Automation catalog entries can now install a bundled script along with the automation, supporting more complete automation setups.
+- **LLM provider connections** — Local agent-server users can manage LLM provider connections from a dedicated interface.
+- **Automation dashboard and discovery** — The automations dashboard, recommendations rail, and Add/Import flow have been updated to make finding and adding automations easier.
+- **Conversation overview and commits** — Conversations now include an overview panel and a unified commits drawer, bringing key conversation information and Git commits together.
+
+## Improvements and fixes
+
+- Agent profiles are no longer silently downgraded.
+- Grouped workspace views now show all folders even when pagination is in use.
+- The LLM selected from the home dropdown now takes precedence over an agent profile's pinned LLM.
+- The `Cmd`+`Enter` build shortcut now applies only in plan mode.
+- Long skill descriptions no longer hide modal actions.
+- PDF previews now render in the built-in viewer.
+- Agent Canvas no longer persists ACP model selections to agent settings when profile discovery fails.
+- The events socket stays alive across refetches and has a bounded handshake, improving connection reliability.
+- Streaming deltas are batched so the UI can keep up with faster models.
