 ## Release history:
 
+* 0.12.0 (2017-12-31):
+  - New API for learning negotiated cipher suite.
+  - Move TLS1.3 support from draft 18 to 22.
+  - Allow server-side MTU configuration.
+  - Tested against latest BoringSSL test suite.
+  - Support RFC5705 exporters.
+  - Provide `ResolvesServerCertUsingSNI` for doing SNI-based
+    certificate switching.
+  - Allow disabling SNI extension on clients, for use with
+    custom server certificate verifiers where the hostname
+    may not make sense.
+  - DNS names are now typesafe, using `webpki::DNSName`.
+  - Update dependencies.
 * 0.11.0 (2017-08-28):
