RIOT-2024.01 - Release Notes
============================
RIOT is a multi-threading operating system which enables soft real-time
capabilities and comes with support for a range of devices that are typically
found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as
light-weight 32-bit processors.
RIOT is based on the following design principles: energy-efficiency, soft
real-time capabilities, small memory footprint, modularity, and uniform API
access, independent of the underlying hardware (with partial POSIX compliance).
RIOT is developed by an international open-source community which is
independent of specific vendors (e.g. similarly to the Linux community) and is
licensed with a non-viral copyleft license (LGPLv2.1), which allows indirect
business models around the free open-source software platform provided by RIOT.
About this release
==================
The 2024.01 release includes:
- Breaking change for board definition due to XFA for pointers to defined MTD.
This means users will need to:
- remove the `MTD_NUMOF` definition from `board.h`
- add `MTD_XFA_ADD(<mtd_dev>, <idx>);` to the definition of `<mtd_dev>`.
- `MTD_0`, `MTD_1`, … defines are no longer needed. Use `mtd_dev_get(0)`,
`mtd_dev_get(1)`, … instead.
- Many fixes to peripherals due to the periph testing shield
- The AVR-8 now has power management
- The ESP32 family is now supported by the SDMMC peripheral driver
- `native` now is supported in pyterm
- `tests/periph/uart_locate_pins` helps discover which pins are where
- the `periph_timer` API supports `periph_timer_query_freqs`
- The GNRC boarder router application supports ZEP topology
- Removal of Kconfig dependency modelling (but still configurations supported)
194 pull requests, composed of 475 commits, have been merged since the
last release, and 4 issues have been solved. 30 people contributed with
code in 64 days. 1083 files have been touched with 36196 (+) insertions and

RIOT-2023.10 - Release Notes
============================
RIOT is a multi-threading operating system which enables soft real-time
capabilities and comes with support for a range of devices that are typically
found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as
light-weight 32-bit processors.
RIOT is based on the following design principles: energy-efficiency, soft
real-time capabilities, small memory footprint, modularity, and uniform API
access, independent of the underlying hardware (with partial POSIX compliance).
RIOT is developed by an international open-source community which is
independent of specific vendors (e.g. similarly to the Linux community) and is
licensed with a non-viral copyleft license (LGPLv2.1), which allows indirect
business models around the free open-source software platform provided by RIOT.
About this release
==================
The 2023.10 release includes:
- PSA Crypto API implementation, one step closer to a secure IoT!
- A bunch of default drivers for boards
