 NCS Navigator MDES Module history
 =================================
 
+0.12.0
+------
+
+- Add `#diff` methods to all levels in the specification tree. They produce
+  a computable difference between two instances. (#10)
+- Add `TransmissionTable#child_instrument_table?` and
+  `TransmissionTable#parent_instrument_table?`. The values they return are
+  manually extracted from several sources and stored in files in each version's
+  documents directory. (#28)
+- Drop support for Ruby 1.8.7.
+- Rename `NcsNavigator::Mdes::VariableType::CodeList` to
+  `NcsNavigator::Mdes::CodeList` and
+  `NcsNavigator::Mdes::VariableType::CodeListEntry` to
+  `NcsNavigator::Mdes::CodeListEntry`. In the unlikely event that you had code
+  referring directly to either of these classes, you'll need to adjust it.

 0.11.0

 - Introduce MDES 3.2 support using specification version 3.2.00.00. (#24)
