# Octarine 0.40.0 Changelog Released: 2026-04-01 **Collapsible Lists & Tasks** - Bullet lists and task lists with nested children now show a collapse chevron on hover — click it to fold the nested items out of sight, keeping long outlines manageable. - Collapse state (headings, codeblocks, lists & tasks) are persisted automatically, so collapsed sections stay collapsed when you restart the app. **Performance** - Significantly reduced CPU and memory usage across the app — typing, idle, and workspace switching are all lighter. - Improved workspace watching functions to be more performant and less power consuming. - Reduced CPU spikes during workspace indexing. - Embedding pruning for large workspaces is now much faster. **Improvements** - Date cells in Views now respect your preferred date format. - Ask Octarine & Writing Assistant now shows error messages as toasts when something goes wrong, instead of failing silently. - The task migration flow uses fewer file operations, making it faster and more reliable. **Fixes** - Fixed numeric sorting for grouped Views not ordering correctly. - Fixed an issue where typing `<` or `>` would result in the markdown save converting them to `<` and `>` - Fixed a feedback loop where internal file writes to `.octarine/` would trigger workspace re-scans, burning CPU even when idle. - Fixed editor state from one workspace leaking into another when switching workspaces. - Fixed an issue where corrupt or unreadable config files could silently overwrite valid data on the next save. - Fixed x-callback URL parameters being double-encoded, which broke integrations like Hookmark. - Fixed an issue where tags listed in properties did not appear in the tags tree after switching workspaces until a tag was modified. - Fixed Related Notes not working after a fresh restart until the user opened Ask Octarine during that session. - Fixed properties adding a blank line to the end of the frontmatter when saving.
