Highlights of device support

Switch from wolfssl to mbedtls as default

OpenWrt switched the default cryptographic library from wolfssl to mbedtls. This library is used for HTTPS/TLS in the Webserver providing LuCI and for the cryptographic operations in hostapd. mbedtls provides security updates in their LTS branch without changing the application binary interface (ABI) of the library. wolfssl provides a stable ABI only for a very limited subset of functions. mbedtls allows us to update only mbedtls without the need to recompile and upgrade all users of mbedtls.

Core components update

Core components have the following versions in 23.05.0-rc3:

In addition to the listed applications, many others were also updated.

Upgrading to 23.05.0-rc3

Sysupgrade can be used to upgrade a device from 22.03 to 23.05, and configuration will be preserved in most cases.

:!: Sysupgrade from 21.02 to 23.05 is not officially supported.

Known issues

Final notes

As always, a big thank you goes to all our active package maintainers, testers, documenters, and supporters.

Have fun!
