Note: I strongly recommend upgrading to this release if you already have the v4 beta1,

The Visual artifacts fix makes it worth the effort to upgrade if your cameras show speckles and dropouts with large frame sizes, and OTA should make it easy.

Beta 2 of the 4.0 branch is a bugfix/roundup release fixing:

  • Visual artifacts caused by a very high clock frequency when talking to the camera module. I have lowered the frequency (following advice seen in other projects) to 16.5MHz and this has produced a notable improvement in video quality on all of my camera modules.
    It lowers the maximum framerate/quality that can be achieved, but you can still use fullHD mode at full quality, so the limit is not very low.
    You can revert to the original (20MHz) frequency in your myconfig.h.
  • Bugfixes; including a nasty one where a badly flashed SPIFFS partition could lockup the module during boot (before WiFi Connect). The firmware now tests for truncated files while reading and avoids entering an infinite loop, instead it erases the damaged file and reverts to defaults.
  • A nice clear warning in the console if PSRAM is not enabled
