squeal-postgresql-qq-0.1.2.0: changelog.md

### 0.1.2.0

* New features
  * Officially support statement parameters

    They where technically working prior to this version, but now that I realize
    they can't be made monomorphic I have decided to support them officially in
    their polymorphic form. See the Haddocks for more information.

    I am electing to escalate this to a minor version bump when I think it
    could technically be a patch version (from the standpoint of "whether it
    compiles") to reflect the "officially supported" nature of the feature.

* No-Op improvements
  * Expand and improve the documentation
  * Some internal refactors
