Internal features

These features are intended for use inside Espressif:

  • Preview support for ESP32-H2 and ESP8684 has been added. These SoCs are not generally available, so they are unsupported in this release. Official support will be added in a later esptool release.
  • Added automatic delay for boot time after ESP32 reset in FPGA.

Bug Fixes

  • Fixed build from sources (require wheel only when installing from pip). (#632)
  • Fixed failing flashing process on some supported chips. (#635)
  • Fixed ESP32-C3 package detection. (#638, #639)
  • Fixed test child processes being blocked waiting for the OS pipe buffer to accept more data. (#637)
  • Fixed MacOS USB PID detection on tty and cu ports.
  • Fixed erroneous comparison when handling deflated data. (#650)

Miscellaneous Changes

  • Changed unnecessarily alarming error to a warning. (#631)
  • Removed ESP32 rev0 connection workaround.
  • Added a readable error and a use example to merge_bin.
