📝 v1.0.11 / Android v1.4.0 Release Notes

Refreshed Android chat interface: simplified header actions, improved account and model selection layout, and added image previews, removal controls, and vision-model guidance.
Smoother desktop streaming: reduced visible jitter during continuous model output so long replies are easier to read.
Android input system rebuilt: inspired by mainstream chat apps, the bottom bar now opens a bottom input sheet for stable editing while keeping chat context visible.
Android data-preserving upgrades: debug APKs now use stable signing, so future versions can install over the previous app and keep chat history/session state.
Android keyboard avoidance fixed: keyboard height is measured from visible screen bounds so the IME does not cover the composer.
Android web search: chat now uses the platform search-chat route with automatic search, plus a visible web-search toggle for forced lookup.
Android streaming display improved: live updates are paced closer to reading speed to reduce flicker and rapid screen churn.
Android long-response scrolling fixed: streaming now follows the measured message height instead of stopping on the first screen, while manual scrolling remains available.
Faster visible Android streaming: the UI render interval is reduced from 180 ms to 100 ms without throttling model or network throughput.
Android image recognition fixed: multimodal image content is preserved by the platform, and image requests on text-only Qwen3.6 automatically switch to GPT-5.6 Terra.
Faster Android startup: signed-in users see cached chat immediately while account, balance and models refresh in the background; temporary network failures no longer erase local history.
