Hi, Today we are switching our branches around, so that the development branch focuses on Mbed TLS 3.0, to be released mid-year. This will include API-breaking changes. 2.x development work will continue on the development_2.x branch. After merging development_3.0 onto development, the development_3.0 branch will be removed. There is no change to the process for submitting PRs: new PRs should continue to target development, with backports to 2.x and 2.16 as needed. (The exception would be a bug-fix that only affects older branches, which would only need ports to the affected branches and not to development). As part of the 3.0 work, we are looking at various things that can be removed from the library. For some of these, we’ve notified the mailing list – please let us know in the next week if you have a good reason for retaining the feature in question. - Remove support for TLS 1.0, TLS 1.1 and DTLS 1.0 https://github.com/ARMmbed/mbedtls/issues/4286 - Remove support for the "Truncated HMAC" (D)TLS extension https://github.com/ARMmbed/mbedtls/issues/4341 - Remove support for 3DES ciphersuites in (D)TLS https://github.com/ARMmbed/mbedtls/issues/4367 - Remove support for RC4, Blowfish, XTEA, MD2 and MD4 https://github.com/ARMmbed/mbedtls/issues/4084 - Remove support for pre-v3 X.509 certificates with extensions https://github.com/ARMmbed/mbedtls/issues/4386 - Remove the RSA key mutex https://github.com/ARMmbed/mbedtls/issues/4124 - Remove MBEDTLS_CHECK_PARAMS https://github.com/ARMmbed/mbedtls/issues/4313 - 3.0 and 2.x :- Minimum development environment: is it OK to require Python >= 3.6 and/or CMake >= 3.5.2? https://lists.trustedfirmware.org/pipermail/mbed-tls/2021-March/000319.html Dave Rodgman

Mbed TLS 3.0 branching

by Dave Rodgman

Hello Mbed TLS users, As previously announced, we are going to switch the focus of Mbed TLS development onto the upcoming 3.0 release. * We have created the development_2.x branch, currently aligned with the tip of development * For the next two weeks, we will keep development and development_2.x in sync (daily) * On April 22, we will merge development_3.0 into development, and remove development_3.0 This means that after April 22: * development will contain API-breaking changes * new features will not normally be back-ported to development_2.x (unless there is a compelling reason to do so) * relevant bugfixes will be backported as normal Impact for users: * users of development should consider whether they should switch to using development_2.x * authors of PRs requiring backports may require an additional backport to development_2.x Regards Dave Rodgman
