Dear RIOT community,
we are delighted to announce that version 2023.01 of RIOT has been released. This release marks the tenth anniversary of RIOT! Happy birthday RIOT and many thanks to everyone involved! 
A detailed log of changes, as well as a short introduction to the project, can be found in the release notes , and downloads are available through GitHub .
Given that no of the API changes are breaking user facing API changes and that some bug fixes relevant for security or correct operation have accumulated, an update is highly recommended.
Happy hacking,
Kaspar, Koen and the RIOT developer community
