[mbed-tls] New releases: Mbed TLS 3.4.1 and 2.28.4 LTS

Hi Mbed TLS users,

We are releasing Mbed TLS 3.4.1 and 2.28.4 LTS.

As the point release suggests, this is a small update which primarily addresses some expiring test certificates.

Full details are available via the release notes:

https://github.com/Mbed-TLS/mbedtls/releases/tag/v3.4.1

https://github.com/Mbed-TLS/mbedtls/releases/tag/v2.28.4

We recommend all users to consider whether they are impacted, and to upgrade appropriately.

Thanks,

The Mbed TLS team
