MicroPython 2.0 Migration Guide
4+
===============================
5+
6+
MicroPython 2.0 is the (currently in development, not yet available) next major
7+
release of MicroPython.
8+
9+
After maintaining API compatibility for almost a decade with the ``1.x`` series, in
10+
order to unblock some project-wide improvements MicroPython 2.0 will introduce a
11+
small number of breaking API changes that will require some programs to be
12+
updated. This guide explains how to update your Python code to accommodate these
13+
changes.
14+
15+
This document is a work-in-progress. As more work is done on MicroPython 2.0,
16+
more items will be added to the lists below.
17+
18+
**Note:** There are currently no MicroPython 2.0 firmware builds available for
19+
download. You can build it yourself by enabling the ``MICROPY_PREVIEW_VERSION_2``
20+
config option. As it gets closer to being ready for release, builds will be
21+
provided for both ``1.x.y`` and ``2.0.0-preview``.
22+
23+
Hardware and peripherals
24+
------------------------
25+
26+
Overview
27+
~~~~~~~~
28+
29+
The goal is to improve consistency in the :mod:`machine` APIs across different
30+
ports, making it easier to write code, documentation, and tutorials that work on
31+
any supported microcontroller.
32+
33+
This means that some ports' APIs need to change to match other ports.

40+
OS & filesystem
41+
---------------
42+
43+
Overview
44+
~~~~~~~~
45+
46+
The primary goal is to support the ability to execute :term:`.mpy files <.mpy
47+
file>` directly from the filesystem without first copying them into RAM. This
48+
improves code deployment time and reduces memory overhead and fragmentation.
49+
50+
Additionally, a further goal is to support a more flexible way of configuring
51+
partitions, filesystem types, and options like USB mass storage.
52+

58+
CPython compatibility
59+
---------------------
60+
61+
Overview
62+
~~~~~~~~
63+
64+
The goal is to improve compatibility with CPython by removing MicroPython
65+
extensions from CPython APIs. In most cases this means moving existing
66+
MicroPython-specific functions or classes to new modules.
67+
68+
This makes it easier to write code that works on both CPython and MicroPython,
69+
which is useful for development and testing.
