- version 3.0
* Breaking changes

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.

+ 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)

* 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
