ISTM that the following changes might be interesting for us:

• addition of hex/fromhex methods to bytes/memoryview/bytearray (so we can drop binascii.{,un}hexlify usage)
• dictionary union (PEP 584)
• UTF-8 validation of all strings
• support for __dict__ on module object
• STM32H723 support

There is now an option to have the GC heap split across more than one pool of memory, although this is not yet in use by the ports.

[matejcik]

also this one is possibly interesting:

A new port has been added, the "embed" port, which is a port of MicroPython that targets the C language and outputs a set of self-contained .c and .h files for embedding into a wider project. An example is provided to show how this works.
