 mbed TLS ChangeLog (Sorted per branch, date)
 
+= mbed TLS x.x.x branch released xxxx-xx-xx
+
+Bugfix
+   * Fix compilation warnings with IAR toolchain, on 32 bit platform.
+     Reported by rahmanih in #683
+   * Fix braces in mbedtls_memory_buffer_alloc_status(). Found by sbranden, #552.
+   * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
+     configure the maximum length of a file path that can be buffered when
+     calling mbedtls_x509_crt_parse_path().
+   * Fix redundant declaration of mbedtls_ssl_list_ciphersuites. Raised by
+     TrinityTonic. #1359.
+   * Fix an issue with MicroBlaze support in bn_mul.h which was causing the
+     build to fail. Found by zv-io. Fixes #1651.
+   * Fix for redefinition of _WIN32_WINNT to avoid overriding a definition
+     used by user applications. Found and fixed by Fabio Alessandrelli.
+
+Changes
+   * Support TLS testing in out-of-source builds using cmake.
