New Features

This week's release focused on reliability and quality improvements across the product.

Bug Fixes

  • Images display more reliably — Images in the chat that occasionally failed to load will now automatically retry and appear correctly instead of showing a placeholder.

  • User preferences save correctly — In some cases, preference changes were being saved as organization-wide settings instead of per-user. This is now fixed.

  • Admin panel seat revocation — After revoking a user's access, the admin panel now displays the correct user name instead of "undefined."

  • Longer multi-step tasks no longer stop early — The assistant can now carry out longer, more complex design operations without stopping partway through.

  • Sessions with unavailable attachments open correctly — Sessions where some file previews couldn't be loaded were sometimes failing to open. They now load correctly even if individual attachments are inaccessible.

  • High-resolution images are now accepted — Images larger than 2,000px were previously rejected. They are now automatically resized so the assistant can reference them in the chat.

  • STEP file analysis is more reliable — Complex STEP files that were timing out during review will now automatically retry using a fallback approach, reducing failures when importing geometry.

  • New messages interrupt generation immediately — Sending a new message while the assistant is still generating a response now cleanly stops the previous reply right away.

  • Document export timeouts reduced — Large document exports are less likely to fail due to a timeout.

  • Expanded geometry for generated designs — Leo can now generate designs that include regular polygon profiles (hexagons, octagons, etc.), slot features, and rotated work planes, broadening the range of shapes available in a single session. A crash that could occur during final model cleanup is also fixed.
