 ## Unreleased
 
+## [0.10.0]
+
 ### Feature
 
 - Add Orphante diseases (`OrphaDisease`) to Ontology
 - Filter gene and disease annotations in subontology based on association with phenotypes
 - Add binary version 3
 - Add new example ontology
 
+### Documentation
+
+- Change orders of methods in `Ontology` to clean up the documentation.
+
 ### Refactor
 
+- Improve the OBO parser with better error handling
 - [**breaking**] Add `Disease` trait that is needed to work with `OmimDisease` and `OrphaDisease`
 - Update example ontology
 - Update unit- and doctests to align with updated example ontology
