+Bugfix
+   * In CTR_DRBG and HMAC_DRBG, don't reset the reseed interval in seed().

+Bugfix
+  * In PEM writing functions, fill the trailing part of the buffer with null
+    bytes. This guarantees that the corresponding parsing function can read
+    the buffer back, which was the case for mbedtls_x509write_{crt,csr}_pem
+    until this property was inadvertently broken in Mbed TLS 2.19.0.
+    Fixes #3682.

+Bugfix
+   * Fix a memory leak in mbedtls_mpi_sub_abs() when the result was negative
+     (an error condition) and the second operand was aliased to the result.
+   * Fix a case in elliptic curve arithmetic where an out-of-memory condition

+API changes
+   * The numerical values of the PSA Crypto API macros have been updated to
+     conform to version 1.0.0 of the specification.
+   * PSA_ALG_STREAM_CIPHER replaces PSA_ALG_CHACHA20 and PSA_ALG_ARC4.
+     The underlying stream cipher is determined by the key type
+     (PSA_KEY_TYPE_CHACHA20 or PSA_KEY_TYPE_ARC4).
+New deprecations
+   * PSA_KEY_TYPE_CHACHA20 and PSA_KEY_TYPE_ARC4 have been deprecated.
+     Use PSA_ALG_STREAM_CIPHER instead.
