MBEDTLS_THREADING_C is defined. Found by TrinityTonic, #1095
* Fix a bug in the update function for SSL ticket keys which previously
invalidated keys of a lifetime of less than a 1s. Fixes #1968.
+ * Add missing parentheses around parameters in the definition of the
+ public macro MBEDTLS_X509_ID_FLAG. This could lead to invalid evaluation
+ in case operators binding less strongly than subtraction were used
+ for the parameter.
Changes
* Add tests for session resumption in DTLS.
