+## v0.7.0
+
+### Breaking changes
+
+- Removed `ConnectionPool` constructor, use `Store.initConnectionPool()` instead
+- Removed `Storable.prototype._id`, use `Storable.prototype.id` from now on
+
+### Possibly breaking changes
+
+- Restructured the whole package, most notably the "lib/sqlstore" directory is gone. If your application directly requires modules of ringo-sqlstore you'll need to adapt the module paths.
+
+### Bugfixes and Improvements
+
+- Switched to [HikariCP](https://github.com/brettwooldridge/HikariCP) as connection pool exclusively. All configuration options accepted by HikariCP can be specified in the configuration hash passed as argument to `Store.initConnectionPool()`.
+- Added support for auto incremented IDs. From now on ID mappings can define either `autoIncrement: true` or `sequence: <name>`. The default is auto increment.
+- Added basic support for `json` and `jsonb` PostgreSQL data types (contributed by [@botic](https://github.com/botic/)). Note that currently the sqlstore query language doesn't support JSON queries.
+- Primitive or object mapping definitions can now contain a `unique` flag. [#33](https://github.com/grob/ringo-sqlstore/issues/33)
+- `Store.prototype.syncTables()` creates a sequence only if it doesn't already exist. [#35](https://github.com/grob/ringo-sqlstore/issues/35)
+- Fixed whitespace matching the empty string in query grammar [#32](https://github.com/grob/ringo-sqlstore/issues/32)
+- Data types are now database specific, fixing [19](https://github.com/grob/ringo-sqlstore/issues/19)
+- Added special SQL generator for Oracle, fixing [#27](https://github.com/grob/ringo-sqlstore/issues/27)
