+### v2.0.0
+* Breaking changes to default AES mode
+  - Moving to [SJCL](http://bitwiseshiftleft.github.io/sjcl/) compatible AES
+  - AES now uses only authenticated modes ("GCM" and "CCM")
+  - Deprecating streaming and file AES encryption. This would be better handled
+    by another library. Gibberish will focus on compatibility with Javascript/Browser encryption.
+  - 1.x CBC encryption/decryption is still available. You can still encrypt and decrypt
+    older Gibberish generated AES ciphertexts, but you must call it explicitly
+* Breaking change to HMAC - User must explicitly choose a digest. No longer defaults to SHA1
+* Deprecating Ruby 1.9.3 since its OpenSSL bindings do not allow for authenticated modes
+
