+   * In modules that implement cryptographic hash functions, many functions
+     mbedtls_xxx() now return int instead of void, and the corresponding
+     function mbedtls_xxx_ret() which was identical except for returning int
+     has been removed. This also concerns mbedtls_xxx_drbg_update(). See the
+     migration guide for more information. Fixes #4212.

+Rename mbedtls_*_ret() cryptography functions whose deprecated variants
+have been removed
+-----------------
+
+This change affects users who were using the `mbedtls_*_ret()` cryptography
+functions.
+
+Those functions were created based on now-deprecated functions according to a
+requirement that a function needs to return a value. This change brings back the
+original names of those functions. The renamed functions are:
+
+| name before this change      | after the change         |

+
+To migrate to the this change the user can keep the `*_ret` names in their code
+and include the `compat_2.x.h` header file which holds macros with proper
+renaming or to rename those function in their code according to the list from
+mentioned header file.
