0.60.0 - a serial console, and logs
The target's serial console in the browser, the target's kernel log over the network, the device's own log live, and images the device downloads by itself.
-
0.52.2 - Fixed: no picture on the M5Stack PoE-P4 after the target switches to a text console
The picture vanished when the target switched to a text console, and the firmware had an answer for exactly that - behind a check the board could never pass.
-
0.52.1 - Fixed: after an update the device rolled back to the old version
An update would install, reboot, and come back as the old version. The new image was never the problem - it never ran. The firmware on its way out broke the boot behind it.
-
Compiled for a debugger all along
0.46.2 is the first build at -O2. Also why a device with 314 KB of free RAM could not find 155 KB of it, and a watchdog that now reboots instead of writing a warning.
-
Twelve minutes of blocks, then twelve minutes of fine
The still-screen fault was an int32 overflow in the H.264 rate controller. Why raising the bitrate made it worse, how the arithmetic was checked on hardware, and why the fix is a one-line version bump.

Four releases at once - crash dumps, a hotspot, four more boards
0.42.2 to 0.45.0 in one post: a panic now leaves a file you can read, a device with no password and no cable puts out its own hotspot, any key press wakes a sleeping target, and four more ESP32-P4 boards have images.
-
0.42.1 - the keyboard that died while the machine slept
A target woke from sleep with no power on its USB port, and the device could only say "USB is not active". It tells the two silences apart now.
-
A serial monitor, and readers for firmware images, panics and EDIDs
A serial monitor that needs no terminal, and three readers: a firmware image, a panic dump, an EDID. All in the browser, nothing uploaded.
-
0.41.0 - more of the KVM in Home Assistant
An update entity, a camera holding a still of the target's screen, the jiggler as a switch, and the numbers worth having when something is wrong.
-
0.28.0 - reading the screen as text, and watching it while you are away
Select and copy the words off a BIOS screen instead of typing them out, and let the device raise an alert when a phrase you care about appears.
-
0.25.0 - the device keeps its own log
A log that survives a restart, so the boot that failed is still readable after the device has come back on something that works.
