 - Build: chiaki's build script starts the native build clean when chiaki's build files change. The OpenSSL upgrade otherwise failed on a machine that had built before (old configured headers left in the cache).
 
 ## Unreleased
+- **Home: one tile per PC (handheld, Saleh):** Home shows each paired PC as one tile (its name, Running when a game runs, Offline when it's off) instead of every PC game. Pressing it opens All games on that PC's games; long press (or X) opens the PC's menu (Show its games, Wake, Pair, Resume, …). A PC game played recently brings its PC's tile forward. PlayStation, Xbox and added apps keep their own tiles. All games has a tab per PC when there's more than one.
 - **PS5 decode latency (Saleh: PXPlay decodes in under 1 ms on the Odin 2, MoonCast showed up to 5 ms):** the Odin's Snapdragon 8 Gen 2 has a separate low-latency HEVC/H.264 decoder (`c2.qti.hevc.decoder.low_latency`) next to the default one, and the PS5 player always got the default one, which holds frames back. With Decoder set to Low latency or Ultra low latency, MoonCast now uses the low-latency decoder when the device has one (Snapdragon `.low_latency`, MediaTek `.lowlatency`). Also: Qualcomm decoders run at full speed (operating-rate), and the thread that hands frames to the screen has display priority.
   - **Measured the same way as other players now:** Decode time is from a frame being queued to the decoder until the decoder hands it back, taken before the frame goes to the screen (it included the hand-off before). Detailed stats add **Render wait**: from decoded to really on screen (the wait for the next refresh, plus Frame pacing's hold), on Android 13 and newer.
   - Measured on the Odin 2 Portal (PS5-423 home screen, 1080p60 HEVC, mostly still, ~0.3 Mbps): decode Standard 3.9 ms, Low 3.7 ms (low-latency decoder), Ultra 2.8 ms; render wait 0.2 ms with Frame pacing Lowest delay, 7.4 ms Balanced, 12.3 ms Smoothest. The PS5's earlier "up to 5 ms" also counted handing the frame to the screen. Frame pacing is the bigger delay: keep Lowest delay for the quickest picture.
