API Changes
- * Add a common error code for a feature that is not supported by the
- underlying alternative implementations.
+ * Add a common error code of `MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED` for
+ a feature that is not supported by underlying alternative
+ implementations implementing cryptographic primitives. This is useful for
+ hardware accelerators that don't implement all options or features.
New deprecations
- * All the current module specific errors that mean a feature is not available
- are deprecated, so the platform error should be used.
- * All the module specific generic hardware accelaration errors that existed
- are deprecated, so the platform error should be used.
+ * All module specific errors following the form
+ MBEDTLS_ERR_XXX_FEATURE_UNAVAILABLE that indicate a feature is not
+ supported are deprecated and are now replaced by the new equivalent
+ platform error.
+ * All module specific generic hardware accelaration errors following the
+ form MBEDTLS_ERR_XXX_HW_ACCEL_FAILED that are deprecated and are replaced
+ by the equivalent plaform error.
Bugfix
* Fix wrong order of freeing in programs/ssl/ssl_server2 example
