# WorkersPanel 5.0.13

## Path, styling and session isolation repair

- Reworked base path detection so clean URLs like `/management/clock` and `/admin/clock` load assets from the correct install folder.
- Added missing clock routes to the path map.
- Added per-install PHP session names and cookie paths so multiple installs on the same host do not share login state.
- Keeps live database settings, logo and favicon untouched.
