About Delta Chat
Delta Chat patches a Team Profile regression and moves its Tauri build out of the repo.
The desktop client runs on a roughly weekly cadence. 2.59.0 added reactions on channel posts, a hideable window menu bar and experimental Team Profiles; 2.59.1 followed eight days later to fix messages staying unread when read from another device, a regression affecting profiles created with Team Profile enabled. The same patch adds Arabic, Telugu and Slovenian, and moves the Tauri edition to its own repository.
