+Core:
+
+* Non-functional changes: some configuration warnings suppressed in Web Builder builds, delta kinematics updated to not use deprecated functionality.
+
+Drivers:
+
+* ESP32: fixed typos and incorrect preprocessor code in some untested board maps.
+
+Plugins:
+
+* SD card, YModem protocol: changed to use local input buffer due to not working when Laserburn cluster plugin was enabled. Ref. [ioSender issue #443](https://github.com/terjeio/ioSender/issues/433).
