About this release
==================
The 2022.07 release includes:
The 2022.07 release includes many changes, some highlights of which are:
## List of notable changes here ##
### GPIO Low-level drivers
GPIO_LL
A new API, `gpio_ll`, has been introduced for highly efficient access to GPIO
pins grouped in ports.
18167
The API is limited to internal use for the time being, but still paves the way
towards using port multipliers like local GPIO pins, and for improved
bit-banging implementations (e.g. around WS281x-style LEDs).
SUIT
### Improved serial port selection
Rust modules
When using multiple boards simultaneously, a new serial port selection
algorithm can be activated by setting `MOST_RECENT_PORT=1`. Of all serial ports
whose metadata matches the board's known properties, it selects the most
recently connected one.
### ESP support
The ESP IDF (IoT Development Framework; the vendor's provided tools) has been
upgraded to version 4.4, and many peripheral drivers are now implemented using those.
