@ -33,6 +33,16 @@ 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.
* Fix the build on ARMv5TE in ARM mode to not use assembly instructions
that are only available in Thumb mode. Fix contributed by Aurelien Jarno
in #2169.
* Fix undefined memset(NULL) call in test_suite_nist_kw.
* Make NV seed test support MBEDTLS_ENTROPY_FORCE_SHA256.
* Fix propagation of restart contexts in restartable EC operations.
This could previously lead to segmentation faults in builds using an
address-sanitizer and enabling but not using MBEDTLS_ECP_RESTARTABLE.
Changes
* Make it easier to define MBEDTLS_PARAM_FAILED as assert (which config.h
