+   * 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.

+Bugfix
+    * Switch to milliseconds as the unit for ticket creation and reception time
+      instead of seconds. That avoids rounding errors when computing the age of
+      tickets compared to peer using a millisecond clock (observed with GnuTLS).
+      Fixes #6623.

+/** \file metatest.c
+ *
+ *  \brief Test features of the test framework.
+ *
+ * When you run this program, it runs a single "meta-test". A meta-test
+ * performs an operation which should be caught as a failure by our
+ * test framework. The meta-test passes if this program calls `exit` with
+ * a nonzero status, or aborts, or is terminated by a signal, or if the
+ * framework running the program considers the run an error (this happens
+ * with Valgrind for a memory leak). The non-success of the meta-test
+ * program means that the test failure has been caught correctly.
+ *
+ * Some failures are purely functional: the logic of the code causes the
+ * test result to be set to FAIL. Other failures come from extra
+ * instrumentation which is not present in a normal build; for example,
+ * Asan or Valgrind to detect memory leaks. This is reflected by the
+ * "platform" associated with each meta-test.
+ *
+ * Use the companion script `tests/scripts/run-metatests.sh` to run all
+ * the meta-tests for a given platform and validate that they trigger a
+ * detected failure as expected.
