 Bugfix
-   * Add a check if iv_len is zero, and return an error if it is zero. reported
-     by roberto. #716
-   * Replace preproccessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
+   * Add a check if iv_len is zero in GCM, and return an error if it is zero.
+     Reported by roberto. #716
+   * Replace preprocessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
      to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
      always be implemented by pthread support. Fix for #696
-   * Fix resource leak on windows platform, in mbedtls_x509_crt_parse_path.
-     In case of failure, when an error occures, goto cleanup.

+   * Fix a resource leak on Windows platforms in mbedtls_x509_crt_parse_path(),
+     in the case of an error. Found by redplait. #590
    * Add MBEDTLS_MPI_CHK to check for error value of mbedtls_mpi_fill_random.
      Reported and fix suggested by guidovranken in #740
    * Fix a potential integer overflow in the version verification for DER
