RIOT-2025.01 - 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 2025.01 release includes:
More work done to update the legacy `netdev` API to its new version `new_netdev_api`
(#20978, #21012, #21015, #21016, #21020, #21028, #21091, #20991). This means
that if you are still using the legacy `netdev` API, start thinking about
updating!
We documented the community processes in a `GOVERNANCE.md` file.
This new file now clearly states all previously undocumented community procedures and
governance, and defines community roles, to further our goals of openness and transparency
within the community.
We also added the `same51-curiosity-nano` board along with some configuration
improvements "across the board" :wink:.
144 pull requests, composed of 280 commits, have been merged since the
last release, and 0 issues have been solved. 32 people contributed with
code in 65 days. 665 files have been touched with 75661 (+) insertions and
6329 deletions (-).

RIOT-2024.10 "FlexTape" - 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
==================
Highlights of the 2024.10 release:
This release fixes some long-standing packet buffer leaks that occurred when using
`gnrc_netif_pktq` and 6LoWPAN or `netdev_new_api` (#20983, #20834).
A long standing-bug in the CC2538 radio driver has been fixed when processing
corrupted frames, that before could render the device unresponsive. This can be
triggered due to radio interference, but we also believe that an attacker within range
of the radio could send crafted frames to reliably trigger the issue. We therefore
consider this a denial of service vulnerability and advise all users of the CC2538 to
upgrade to 2024.10 or cherry-pick 1b61216da734fcd40ae0d832b800e4e67975bdc8. More
details are published in the [security advisory](https://github.com/RIOT-OS/RIOT/security/advisories/GHSA-m75q-8vj8-wppw).
With SUIT it is now easier to accept firmwares signed with different keys,
e.g., a node build and signed with a development key can be configured to
accept images signed with either the development key or the production key (#21019).
The public keys are now also stored on the developer's machine, so if a
encrypted private key is used, you don't need the decryption password to build
a firmware, only for signing it (#20862).
`THREAD_CREATE_STACKTEST` is now the default when `DEVELHELP` is used.
This release saw the addition of the `adafruit-metro-m4-express` board.
129 pull requests, composed of 255 commits, have been merged since the
last release, and 5 issues have been solved. 29 people contributed with
code in 119 days. 502 files have been touched with 142126 (+) insertions and
