v26.1.6: Extended Context
You can now use the full 1M context window. Toggle it right from the model selector dropdown - a "1M" badge appears on the chip so you always know when it's active. Opus 4.6, Sonnet 4.6, and Mythos get native 1M support; older Sonnet models use the beta header automatically. Set your default in Settings > AI.
We also added trackpad swipe navigation. Two-finger swipe left or right over the center panel to cycle between tabs - sessions, files, changes, whatever you have open.
