Frozen Warframe SE and other HID panels crash on connect — fixed. Every pip, Fedora and Arch install crashed with AttributeError: 'hid.device' object has no attribute 'nonblocking' the moment one of these panels connected; only Debian escaped it. Two different PyPI packages both import as hid with incompatible APIs, and TRCC drove one against the other. It now detects which one is installed and speaks its API. (#244, #253)
Unplug and replug your panel — it comes back. Before, the device never recovered: TRCC logged a write failure every ~150 ms (one report counted 1800+ in two minutes) and only restarting the app fixed it. Nothing was listening for the unplug, so the dead connection was never released. (#254, #246)
display load-image shows your image instead of a black screen. Unless your file happened to be named 00.png, the panel went black while the command reported success. (#245)
Daemon mode stops crashing on common commands. With TRCC_DAEMON=1, video playback, slideshow, LED play and two API endpoints raised an error instead of working. (#249)
Large backgrounds display on Trofeo Vision panels. Above roughly 512 KB the firmware silently ignored the image and the glass kept showing the previous frame. Big images are now compressed to fit rather than vanishing. (#251)
LED commands aimed at a non-LED device now refuse. trcc led color <lcd-key> ffffff used to answer "LED color set" and exit 0, quietly saving LED settings under an LCD's key. All 21 LED commands now answer in one voice. (#252)
trcc --version works again — plus -V and trcc version. The rebuild dropped it, which made it needlessly hard to say which version you are on when filing an issue. (#247)
The CLI documentation matches the CLI. The reference page is now generated from the commands themselves so it cannot drift again, and 40 stale commands across the guides were corrected — a test checks every documented invocation against the real CLI. (#247)
