+### Fixed
+
+- **Windows session saving**: finalizing a recording (`Session.pack_to_zip`)
+  assumed POSIX file semantics and failed on Windows with
+  `PermissionError: [WinError 32]` — open zarr / `ZipStore` handles can't be
+  deleted or renamed there. Packing now releases handles, retries the folder
+  cleanup, and uses `os.replace`, so saving a recording works on Windows.
+- **Leaked session file handles**: reading a session (`open_session_store`,
+  `ReplaySource`, `iter_labeled_windows` / `iter_aligned_windows`) left the
+  `.session.zip` open, which locks the file on Windows. `Session` is now
+  closeable (and usable as a context manager) and every reader releases the
+  handle when it is done.
+- **VHI connection robustness**: while the Virtual Hand is disconnected, the
+  gRPC state poll backs off and uses a short probe deadline, and repeated
+  failures are deduped/quieted — a closed or absent VHI no longer floods the log
+  or stutters the render loop.
+
 ### Changed (internal)
 
 - CLI tools (`emg_generator`, `lsl_dummy`, `install_vhi`, `webcam`) migrated
   from `argparse` to Typer.
+- Tests + CI: documentation code blocks are parse-checked (and the tagged ones
+  executed) and the example scripts are smoke-run, with the full test suite now
+  running on Linux **and Windows** (previously CI only built the docs).
