Features
* Add new config.h flag MBEDTLS_CHECK_PARAMS that enables validation of
more of the parameters by public API functions (see its documentation in
config.h for details). Disabled by default - requires users to provide an
implementation of the callback function or macro.
* Add a new config.h option of MBEDTLS_CHECK_PARAMS that enables additional
validation of parameters in the library's public interface. This does not
change the API of existing functions, but additional clarity has been
added to the defined documentation interface to make clearer what the
interface is designed to accept. See the corresponding API documentation
for each function to see what parameter values are defined as invalid.
This feature is disabled by default. See its API documentation in
config.h for additional steps you have to take when enabling it.
New deprecations
* Deprecate mbedtls_ctr_drbg_update and mbedtls_hmac_drbg_update
