 ## What's New
 
-### `--json` flag for `list`, `status`, and `doctor`
-Machine-readable JSON output via `-j`/`--json` on the commands that produce tabular data:
-- `gw list -j` — all workspaces as JSON array
-- `gw list <name> -j` — single workspace detail
-- `gw list -sj` — workspace summaries with git status
-- `gw status -j` — repo status for current workspace
-- `gw doctor -j` — health issues as JSON array
+### MCP server for cross-workspace communication
+New `gw mcp-serve` command exposes a stdio JSON-RPC server that lets Claude Code instances in different workspaces communicate via announcements. Auto-configured via `.mcp.json` in workspace directories.
+
+### End-to-end test suite
+Comprehensive e2e tests covering init, create, delete, sync, rename, doctor, presets, MCP server, and more. Runs in Docker locally (`just e2e`) and natively in CI.
+
+### Bug fixes
+- `gw list --json` now returns `[]` instead of a text message when no workspaces exist
+- Git operations no longer hang when SSH key requires a passphrase
+- Repo URL normalization for consistent matching across SSH/HTTPS variants
+- Announcement TTL pruning to prevent unbounded state growth
