## [fix: removed multithreaded buffer usage]($section.id("2025-06-03T18:28:43+02:00"))
The `project_manger` and `diff` modules run in the background asynchronously. These modules access
buffers, potentially from a different thread to the main buffer manager. While the buffer itself is
technically threadsafe, there is not yet any kind of threadsafe buffer lifetime management. That
means that buffers may get deleted while the differ or LSP is serializing them. At some point the
buffer manager should provide some method of locking buffer lifetimes to prevent them from being
deleted while in use.
For now I have prevented multithreaded buffer access by removing all buffer serialization in
background tasks. This means a very minor increase in latency for these operations, but much
improved stability.
## [added highlight_columns_enabled config option]($section.id("2025-06-03T18:26:44+02:00"))
This new option will disable `highlight_columns` without unconfiguring them entirely. Also, the
command `toggle_highlight_columns` is now persistent.
## [base16 theme collection]($section.id("2025-05-26T11:57:39+02:00"))
Added the entire base16 theme collection to flow-themes.
