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

* 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.

* 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)

* Set a write timeout in pyserial (prevents hanging in sync process if port is unavailable).
* (ESP32) New option elf2image --secure-pad to pad the output binary so once signed it will align to an flash cache page boundary (64KB). Prevents unsigned data from being mapped into the instruction space via the flash cache.

* ESP8266 changes + Move the loader stub to the very end of IRAM (useful when using load_ram command). + elf2image --version=2 is now compatible with recent ESP8266 SDK bootloader and produces the same binary output as ESP8266 SDK gen_app.py. + Remove unsupported flash size 4MB-c2
* ESP32 changes + Print chip frequency rating values in Features list, for chips where these are set. + Working load_ram command. + espefuse.py: Support setting the baud rate. + New --override-vddsdio option allows setting the VDDSDIO regulator to 1.8V, 1.9V or \"OFF\" when connecting (to override the default value read from efuse). + To avoid hardware damage, forcing VDDSDIO to 3.3V is not supported.
* Tue Dec 04 2018 Matej Cepl - Remove superfluous devel dependency for noarch package
