+Changes
+   * Add extra printf compiler warning flags to builds.
+Requirement changes
+   * The library now uses the %zu format specifier with the printf() family of
+     functions, so requires a toolchain that supports it. This change does not
+     affect the maintained LTS branches, so when contributing changes please
+     bear this in mind and do not add them to backported code.

-Security
-   * Fix a security reduction in CTR_DRBG when the initial seeding obtained a
-     nonce from entropy. Applications were affected if they called
-     mbedtls_ctr_drbg_set_nonce_len(), if they called
-     mbedtls_ctr_drbg_set_entropy_len() with a size that was 3/2 times the key
-     length, or when the entropy module uses SHA-256 and CTR_DRBG uses AES-256.
-     In such cases, a random nonce was necessary to achieve the advertised
-     security strength, but the code incorrectly used a constant instead of
-     entropy from the nonce.
-     Found by John Stroebel in #3819 and fixed in #3973.
