## 0.15.0 - 2020-09-14

* Upgrade to use modern mongo by upgrading to use the mongo 2.0 driver.

  This update means MongoMapper should work with any version of mongo after (2.6+).

  Many thanks to Frederick Cheung <frederick.cheung@gmail.com> for his contribution.

  Note that MyModel.collection now returns a mongo 2.0 driver collection object which does not mirror the shell methods.

  Patches welcome for a compatibility layer!

* Support for ruby 2.4+, rails 5.0+
* Dropping support for all older rubies, older rails.

## 0.14.0 - 2017-01-19
## 0.14.0 RC1 - 2016-03-16

### Enhancements:

* Only partially update objects (using $set and $unset) when updates occur.

  Partial Updates can be turned on or off per class (by default they are off):

    ```ruby
    class Person
      include MongoMapper::Document
      self.partial_updates = true
    end
    ```

  [smtlaissezfaire]

* (Optionally) allow only static (defined) keys, and raise errors for keys that haven't been defined (mimic Mongoid's allow_dynamic_fields = false).

  Turn this on, per model, with:

    ```ruby
    class Person
      include MongoMapper::Document
      self.static_keys = true
    end

    p = Person.new
    p['non_defined_key'] = 'foo' # => MissingKeyError
    ```

* Fix issues with set_collection_name nullifying SCI on 1.8 [cheald]
* Disable SCI when an inherited model explicitly changes its collection. Closes [cheald][#396]
