Hi Mbed TLS users,
We have released Mbed TLS version 3.6.5.
These releases of Mbed TLS address several security issues, provide bug fixes, and bring other minor changes. Full details are available in the release notes https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-3.6.5.
We recommend all users to consider whether they are impacted, and to upgrade appropriately.
I am happy to announce the joint-release of Mbed TLS 4.0.0-beta & TF-PSA-Crypto 1.0.0-beta
PSA-Crypto now lives in its own repository while TLS and X.509 remain in Mbed TLS.
This beta release breaks compatibility with earlier versions of Mbed TLS.
Please do not use it in production.
It’s intended for the community to verify codebase integrations against the split and API changes, and for early adopters to experiment and provide feedback.
For full details, please see the release pages:
Mbed TLS 4.0.0-beta: https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-4.0.0-beta
TF-PSA-Crypto 1.0.0-beta: https://github.com/Mbed-TLS/TF-PSA-Crypto/releases/tag/tf-psa-crypto-1.0.0-…

Dear Mbed TLS users,
We have released Mbed TLS versions 3.6.3 and 2.28.10. These releases provide bugfixes, security fixes and minor improvements.
This release of Mbed TLS provides the fix for the TLS compatibility issue of handling fragmented handshake messages. This release includes fixes for security issues.
Full details are available in the release notes:

Dear Mbed TLS users,
The next release of Mbed TLS (3.6.3 and 2.28.10) is scheduled on Monday
2025-03-24. It will include a security fix for a vulnerability with a
high impact to affected applications.
Due to the nature of the vulnerability, which involves an insecure
default in current versions of Mbed TLS, fixing it may require a small
change in application code. We will provide instructions in the release
notes. Without this change, affected applications will fail at runtime
with Mbed TLS 3.6.3 or 2.28.10. Applications that are currently secure
will generally not require any change.
We apologize for the inconvenience.
Best regards,
--

Dear Mbed TLS and PSA Crypto users,
We would like to update you on the release timeline for Mbed TLS 4.0/TF-PSACrypto1.0 release.
As a reminder, the key objectives of the release are a separate TF-PSA Crypto repo., PSA Crypto becoming the de facto Crypto API and Mbed TLS using PSA Crypto APIs as the crypto API by default.
While TF-PSA Crypto repository is now available, the remaining effort to be ready for the release is more than we originally planned for.
Based on remaining effort estimates, we plan to make Mbed TLS 4.0-Beta and TF-PSA Crypto 1.0-Beta release around end of June. The Mbed TLS 4.0, and TF-PSA Crypto 1.0 release is expected around end of September.
We don’t expect users to integrate the Beta release. Beta is aimed to pipeclean the separate Mbed TLS and TF-PSA Crypto release process and get any early feedback. The release in September is expected to be integrated by users to their projects.
We wanted to provide these revised release dates so that the users can plan accordingly. In the meantime, bug fixes and security fixes will continue to be provided via. Mbed TLS 3.6.x LTS releases.
Thanks,
Mbed TLS/PSA Crypto Maintainers.
Dear Mbed TLS users,
Mbed TLS has contained the reference implementation of the PSA Crypto API since the early days of the standard. This implementation was experimental at first, but over years of development it reached maturity, and the experimental status was removed three years ago (in version 3.6.1.).
Shortly after that, in 2022, the TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> repository was created just for the PSA Crypto API implementation to make it more accessible for users only interested in that. This repository was only a mirror of the main one and the development of the PSA Crypto API implementation remained integral part of Mbed TLS.
In the background, work has been started to make this repository the place where the development of the PSA Crypto API reference implementation happens. This work has finally been completed and from now on TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> is ready to receive contributions, bug reports and enhancement requests. TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> will now be the development repository for the PSA Crypto reference implementation.
Mbed TLS will continue to rely on TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> and will be using it as a submodule.
Many thanks,
