 - Module for mRNA handling, with a function for selecting the primary mRNA from
   a gene or other feature.
 - New CLI command `tag pmrna`.
+- A new `Score` class for internal handling of feature scores. Not yet included
+  in the API, and may not ever be.
 
 ### Changed
 - Modules focused on classes / data structure now support more concise imports
   (for example, `from tag import Feature` and `tag.Feature` now supported and
   preferred over `from tag.feature import feature` and `tag.feature.Feature`).
 
+### Fixed
+- Resolved a bug with the GFF3Writer failing to print `##FASTA` directives
+  before writing sequences to output.
+
 ## [0.1.1] - 2016-12-19
 ### Changed
 - CLI implemented using `entry_points` instead of a dedicated script.
