+- update to 2.15:
+  Fix a bug where the name constraint extension did not constrain the alternative
+  DN field which can be included in a subject alternative name. This would allow
+  a corrupted sub-CA which was otherwise constrained by a name constraint to
+  issue a certificate with a prohibited DN.
+
+  Fix a bug in the TLS server during client authentication where where if a
+  (disabled by default) static RSA ciphersuite was selected, then no certificate
+  request would be sent. This would have an equivalent effect to a client which
+  simply replied with an empty Certificate message. (GH #2367)
+
+  Replace the T-Tables implementation of AES with a 32-bit bitsliced version. As
+  a result AES is now constant time on all processors. (GH #2346 #2348 #2353
+  #2329 #2355)
+
+  In TLS, enforce that the key usage given in the server certificate allows the
+  operation being performed in the ciphersuite. (GH #2367)
+
+  In X.509 certificates, verify that the algorithm parameters are the expected
+  NULL or empty. (GH #2367)
+
+  Change the HMAC key schedule to attempt to reduce the information leaked from
+  the key schedule with regards to the length of the key, as this is at times (as
+  for example in PBKDF2) sensitive information. (GH #2362)
+
+  Add Processor_RNG which wraps RDRAND or the POWER DARN RNG instructions. The
+  previous RDRAND_RNG interface is deprecated. (GH #2352)
+
+  The documentation claimed that mlocked pages were created with a guard page
+  both before and after. However only a trailing guard page was used. Add a
+  leading guard page. (GH #2334)
+
+  Add support for generating and verifying DER-encoded ECDSA signatures in the C
+  and Python interfaces. (GH #2357 #2356)
+
+  Workaround a bug in GCC’s UbSan which triggered on a code sequence in XMSS (GH
+  #2322)
+
+  When building documentation using Sphinx avoid parallel builds with version 3.0
+  due to a bug in that version (GH #2326 #2324)
+
+  Fix a memory leak in the CommonCrypto block cipher calls (GH #2371)
+
+  Fix a flaky test that would occasionally fail when running the tests with a
+  large number of threads. (GH #2325 #2197)
+
+  Additional algorithms are now deprecated: XTEA, GOST, and Tiger. They will be
+  removed in a future major release.
