+Features
+   * AES-NI is now supported with Visual Studio.
+   * AES-NI is now supported in 32-bit builds, or when MBEDTLS_HAVE_ASM
+     is disabled, when compiling with GCC or Clang or a compatible compiler
+     for a target CPU that supports the requisite instructions (for example
+     gcc -m32 -msse2 -maes -mpclmul). (Generic x86 builds with GCC-like
+     compilers still require MBEDTLS_HAVE_ASM and a 64-bit target.)
