+     setting the CMake variable of the same name at configuration time.
+
+Bugfix
+   * Fix crypt_and_hash decryption fail when used with a stream cipher
+     mode of operation, due to the input not being a multiple of the block
+     size. Resolves #7417.
+   * Fix a bug where mbedtls_x509_string_to_names() would return success
+     when given a invalid name string, if it did not contain '=' or ','.
+   * Fix missing PSA initialization in sample programs when
+     MBEDTLS_USE_PSA_CRYPTO is enabled.
+   * Fix clang and armclang compilation error when targeting certain Arm
+     M-class CPUs (Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M23,
+     SecurCore SC000). Fixes #1077.
+   * Fixed an issue that caused compile errors when using CMake and the IAR
+     toolchain.
+   * Fix the build with MBEDTLS_PSA_INJECT_ENTROPY. Fixes #7516.
+   * Fix builds on Windows with clang.
+   * Fix compilation warnings in aes.c for certain combinations
