- Fixed share button color contrast (now matches your accent color too!)
- Now support more file types (text/code files)
- (android) New quick-tools menu from composer
- (android) Simplified composer into a unibar
- (ios) Many performance fixes to make the app faster
- Many reliability improvements to cut long “Thinking” chat failure rates by more than half

Lots more to come in the coming weeks both in terms of polish to make the app quicker and shipping long-requested features
