+Changes
+   * The ECP module, enabled by `MBEDTLS_ECP_C`, now depends on
+     `MBEDTLS_CTR_DRBG_C` or `MBEDTLS_HMAC_DRBG_C` for some side-channel
+     coutermeasures. If side channels are not a concern, this dependency can
+     be avoided by enabling the new option `MBEDTLS_ECP_NO_INTERNAL_RNG`.
+
+Security
+   * Fix side channel in mbedtls_ecp_check_pub_priv() and
+     mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a
+     private key that didn't include the uncompressed public key), as well as
+     mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL
+     f_rng argument. An attacker with access to precise enough timing and
+     memory access information (typically an untrusted operating system
+     attacking a secure enclave) could fully recover the ECC private key.
+     Found and reported by Alejandro Cabrera Aldaya and Billy Brumley.

+   * Fix issue in Lucky 13 counter-measure that could make it ineffective when
+     hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT

+ *
+ * When this option is disabled, mbedtls_ecp_mul() will make use of an
+ * internal RNG when called with a NULL \c f_rng argument, in order to protect
+ * against some side-channel attacks.
+ *
+ * This protection introduces a dependency of the ECP module on one of the
+ * DRBG modules. For very constrained implementations that don't require this
+ * protection (for example, because you're only doing signature verification,
+ * so not manipulating any secret, or because local/physical side-channel
+ * attacks are outside your threat model), it might be desirable to get rid of
+ * that dependency.
+ *
+ * \warning Enabling this option makes some uses of ECP vulnerable to some
+ * side-channel attacks. Only enable it if you know that's not a problem for
+ * your use case.
+ *
+ * Uncomment this macro to disable some counter-measures in ECP.
