 #### Added
+- Support for local DNS resolution. [#194](https://github.com/Mashape/kong/pull/194)
+- Support for Debian 8 and Ubuntu 15.04.
 - DAO
   - Cassandra version bumped to 2.1.5
-  - support for Cassandra downtime. If Cassandra goes down and is brought back up, Kong will not need to restart anymore, statements will be re-prepared on-the-fly. This is part of an ongoing effort from [jbochi/lua-resty-cassandra#47](https://github.com/jbochi/lua-resty-cassandra/pull/47), [#146](https://github.com/Mashape/kong/pull/146) and [#187](https://github.com/Mashape/kong/pull/187).

 Queries effectued during the downtime will still be lost. [#11](https://github.com/Mashape/kong/pull/11)
   - Leverage reused sockets. If the DAO reuses a socket, it will not re-set their keyspace. This should give a small but appreciable performance improvement. [#170](https://github.com/Mashape/kong/pull/170)
   - Cascade delete plugins configurations when deleting a Consumer or an API associated with it. [#107](https://github.com/Mashape/kong/pull/107)
   - Allow Cassandra hosts listening on different ports than the default. [#185](https://github.com/Mashape/kong/pull/185)
+- CLI
+  - Added a notice log when Kong tries to connect to Cassandra to avoid user confusion. [#168](https://github.com/Mashape/kong/pull/168)
+  - The CLI now tests if the ports are already being used before starting and warns.
+- Admin API
+  - `name` is now an optional property for APIs. If none is being specified, the name will be the API `public_dns`. [#181](https://github.com/Mashape/kong/pull/181)
+- Configuration
+  - The memory cache size is now configurable. [#208](https://github.com/Mashape/kong/pull/208)
 
 #### Fixed
-- Admin API: responses now have a new line after the body. [#164](https://github.com/Mashape/kong/issues/164)
-- DAO: keepalive property is now properly passed when Kong calls `set_keepalive` on Cassandra sockets.
 - Resolver
   - More explicit "API not found" message from the resolver if the Host was not found in the system. "Api not foun with Host: %s".
   - If multiple hosts headers are being sent, Kong will test them all to see if one of the API is in the system. [#186](https://github.com/Mashape/kong/pull/186)
+- Admin API: responses now have a new line after the body. [#164](https://github.com/Mashape/kong/issues/164)
+- DAO: keepalive property is now properly passed when Kong calls `set_keepalive` on Cassandra sockets.
+- Multipart dependency throwing error at startup. [#213](https://github.com/Mashape/kong/pull/213)
+
+> **internal**
+> - Separate Migrations from the DAO factory.
+> - Update dev config + Makefile rules (`run` becomes `start`).
+> - Introducing an `ngx` stub for unit tests and CLI.
+> - Switch many PCRE regexes to using patterns.
