@ -35,6 +35,9 @@ Bugfix
* Enable Suite B with subset of ECP curves. Make sure the code compiles even
if some curves are not defined. Fixes #1591 reported by dbedev.
* Fix misuse of signed arithmetic in the HAVEGE module. #2598
* Update test certificates that were about to expire. Reported by
Bernhard M. Wiedemann in #2357.
* Make NV seed test support MBEDTLS_ENTROPY_FORCE_SHA256.
Changes
* Make `make clean` clean all programs always. Fixes #1862.
