## 0.4.9.0 [2021.08.30]

* Consolidate the type-synonym expansion functionality with `th-abstraction`,
  which also provides the ability to expand type synonyms. After this change,
  the `th-expand-syns` library is mostly a small shim on top of
  `th-abstraction`. The only additional pieces of functionality that
  `th-expand-syns` which aren't currently available in `th-abstraction` are:

  * `th-expand-syns`' `expandSyns{With}` functions will warn that they cannot
    expand type families (if the `SynonymExpansionSettings` are configured to
    check for this). By contrast, `th-abstraction`'s `applySubstitution`
    function will silently ignore type families.
  * `th-expand-syns` provides a `substInCon` function which allows substitution
    into `Con`s.
  * `th-expand-syns` provides `evade{s}` functions which support type variable
    `Name` freshening that calculating the free variables in any type that
    provides an instance of `Data`.
