+- [ADDED] `include.seperate` with `include.limit` support for HasMany associations.
+- [ADDED] Added default validation based on attribute types. [#3472](https://github.com/sequelize/sequelize/pull/3472). The validation _cannot_ be disabled. If you really want to completely disable it, you can remove the `validate` function from the corresponding datatype, but know that this permanently disables the validation.
+- [ADDED] `describeTable`  now marks the primary key (Reroll of [#3703](https://github.com/sequelize/sequelize/pull/3703))
+- [ADDED] Automatically determine the version of the database upon first connection [#4192](https://github.com/sequelize/sequelize/pull/4192). This will be useful going forward in order to provide support for older database versions.
