    form.

  * Internal features
    These features are intended for use inside Espressif:
    - Support for ESP32-S3-beta3 & ESP32-C6-beta have 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.

    + Decoupled esptool reset logic for easier monkey-patching (#508)
- version 3.0
  * Breaking changes
    + The default esptool.py write_flash --flash_size argument has changed from detect to keep.
      This means that if no --flash_size argument is passed when flashing a bootloader, the value
      in the bootloader .bin file header is kept instead of detecting the actual flash size and
      updating the header. To keep the old behaviour, add the argument esptool.py [...] write_flash [...] -fs detect
    + espefuse.py command line arguments for ESP32 have changed:
      - BLK1, BLK2, BLK3 is now BLOCK1, BLOCK2, BLOCK3`
      - The key usage secure_boot has been replaced with secure_boot_v1, secure_boot_v2.
        Secure Boot V2 is the new RSA-based Secure Boot mechanism supported on ESP32 V3.
  * New Features
    + Support for ESP32-S2 SoC has been added
    + Support for detecting ESP32-PICO-V3-02 and ESP32-U4WDH have been added
    + New --connect-attempts argument (#464)
    + Fixed scrolling problems when output is redirected (for example in Arduino IDE, see discussion at #482)
    + Produce a meaningful error if the SoC we connect to doesn't match the --chip argument
    + Support different capitalization and spelling for --chip argument (ie -c ESP32, -c esp32-s2, etc.
    + Added dedicated program esp_rfc_2217_server.py for flashing via RFC2217 (i.e. flashing over the network, #383)
  * espsecure.py
    + Added support for Secure Boot V2 (ESP32 V3, ESP32-S2)
    + Secure Boot V1: PKCS8 formatted ECDSA keys are now supported via ecdsa library (not including password protected keys)
  * espefuse.py
    + Added ESP32 ECO3 efuse UART_DOWNLOAD_DIS
    + Added new batch burn mode, support burning more than one eFuse on a single command line
    + espefuse.py internals have been refactored to support multiple chips, produce more information about
      which eFuses are being written to which values.
    + "Virtual" mode added for host-based testing, allows updating eFuse values on a "virtual" chip inside the host.
  * Internal features
    + These features are intended for use inside Espressif:
      Support for ESP32-S3beta2 & ESP32-C3 have been added. These SoCs are not currently available
      outside Espressif, so these SoCs are unsupported in this release. Official support will be
      added in a later esptool release.
      esptool.py --no-stub read_flash is now supported on ESP32 and later. This option
      is slower than using the default stub option to read flash, so it's generally not useful for production SoCs.
  * Bug Fixes
    + Added temporary workaround for a pyserial failure on macOS Big Sur Preview (#540)
    + Fixed gcc9 warning in the stub (#501)
    + Fixed some memory types printed in the memory map output
    + Fixed the check for zero bytes before applying an ELF SHA-256 with elf2image --elf-sha256-offset option (#560)
    + Fixed displaying some single core ESP32 features incorrectly, i.e. ESP32-S0WD
    + Fixed exception on Python 3 if the same flash address was repeated twice (#558)
  * Miscellanous Changes
    + Updated miniz to v2.1.0 (#500)
    + Moved ESP32 stub loader location to facilitate loading large applications direct to IRAM
    + Vendored modules ecdsa, pyaes and optional pycrypto have been removed. Pyaes has been replaced
      with the pyca-cryptography library
