+- Typing `?` while the /search bar is open enters it as text instead of opening quick help
+- Add support for Open Plugin Spec v1 plugin manifests and mcp.json configuration
+- IDE integration reconnects reliably when the CLI reloads MCP servers or changes directory
+- Multi-turn subagent timelines show every prompt and response in the correct order after reopening /tasks
+- Subagent timelines identify whether prompts came from the main agent or another subagent
+- Show a first-run splash to opt into the default sandbox
+- Adding support for gemini-3.6-flash
+- The `/mcp add` and `/mcp edit` wizard now preserves `=` characters in environment variable values (such as base64 padding), so secrets and tokens are stored correctly.
+- Remote session uploads stop retrying permanent Mission Control 400/404 responses
+- Show Tab in /settings footer to switch scope tabs
+- Downscale oversized tool-result images so CAPI Responses requests continue
+- When multiplexing sessions, a session's open dialog no longer leaks into another session; eligible pickers reopen when you switch back
+- The `$` interactive shell shortcut now opens a shell even while the agent is working
+- Fully honor the skill disable-model-invocation flag
+- Warn when a participating language server reports a different symbol than the one requested
+- Steering interrupts shell output waits without stopping the running command
+- Increase the Responses request size limit
+- Plan mode now allows session-folder planning artifacts while still blocking clear file mutations outside the session folder.
+- Add `/model plan` (or `/model --plan`) to pick a model used while in plan mode; pass a model id, `off` to clear, or no id to open the picker. Reverts to the session model when you leave plan mode.
+- Resume search matches session titles even when whitespace differs
