+
+Bugfix
+   * Fix crypt_and_hash decryption fail when used with a stream cipher

+   * 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

+
+Changes
+   * Update test data to avoid failures of unit tests after 2023-08-07, and
+     update expiring certififcates in the certs module.
