MicroPython version 1.18 released #Python @micropython

The MicroPython dev team has announced MicroPython, v1.18! There were 335 commits since the last release on September 2021, so there were about 2.5 commits per day since then.

This release of MicroPython sees a boost to the overall performance of the VM and runtime… Performance options are enabled on the esp32, mimxrt, rp2, stm32 and unix ports. For esp32 and mimxrt some code is also moved to RAM to further boost performance. On stm32, performance increases by about 20% for benchmarks that are heavy on name lookups, like misc_pystone.py and misc_raytrace.py. On esp32 performance can increase by 2-3x, and on mimxrt it is up to 6x.

All boards in all ports now have a board.json metadata file, which is used to automatically build firmware and generate a webpage for that board (among other possibilities). Auto-build scripts have been added for this purpose and they build all esp32, mimxrt, rp2, samd and stm32 boards.

Source code and firmware can be downloaded from https://micropython.org/download/
