Latest version of mbedtls is 3.5, but is still 2.x in the PlatformIO registry. Since mbed officially claims not to maintain the configuration of any of the package management tools, it may have been released by ivan in the registry before.
However the last update in the repository was four years ago. Also the github repository for mbedtls has changed from
Mbed-TLS/mbedtls. Can anyone provide an update for it?
GitHub - Mbed-TLS/mbedtls: An open source, portable, easy to use, readable and flexible TLS library, and reference implementation of the PSA Cryptography API. Releases are on a varying cadence, typically around 3 - 6 months between releases.
