 Features
-   * Add support to remove decryption operation for cipher type of AES, ARIA
-     and CAMELLIA. A new configuration option, MBEDTLS_BLOCK_CIPHER_NO_DECRYPT
-     can be used to enable this feature.
-     Note that this configuration option is incompatible with MBEDTLS_DES_C,
-     MBEDTLS_CIPHER_MODE_CBC, MBEDTLS_CIPHER_MODE_XTS and MBEDTLS_NIST_KW_C.
+   * Enable the new option MBEDTLS_BLOCK_CIPHER_NO_DECRYPT to omit
+     the decryption direction of block ciphers (AES, ARIA, Camellia).
+     This affects both the low-level modules and the high-level APIs
+     (the cipher and PSA interfaces). This option is incompatible with modes
+     that use the decryption direction (ECB in PSA, CBC, XTS, KW) and with DES.
