+Bugfix
+   * Fix redundant declaration of mbedtls_ssl_list_ciphersuites. Raised by
+     TrinityTonic. #1359.
+   * Fix for redefinition of _WIN32_WINNT to avoid overriding a definition

+   * Fix braces in mbedtls_memory_buffer_alloc_status(). Found by sbranden, #552.
+   * Fix an issue with MicroBlaze support in bn_mul.h which was causing the

+   * Fix compilation warnings with IAR toolchain, on 32 bit platform.
+     Reported by rahmanih in #683
+
+Changes
+   * Support TLS testing in out-of-source builds using cmake. Fixes #1193.
+   * Changed CMake defaults for IAR to treat all compiler warnings as errors.
