About this release.

Keep project backups and review changes. Very long sessions can grow history and logs; unattended multi-hour runs are still being evaluated. Unsigned builds are identified next to the download. Checksums confirm file integrity, not publisher identity.

When reporting a problem, include your platform, version and steps to reproduce. Remove keys and private project details before sharing logs.

The CLI is in development.

Terminal downloads are temporarily paused while we redesign the client. The Windows desktop app above is the current download.
