0.5.1.0 (2022-05-10)

GHC 9.0.2 and 9.2.2 compatibility.

0.5 (2020-03-18)

GHC 8.8 (and possibly 8.10) compatibility.
safecopy-0.10 compatibility.

0.4.0.1 (2018-10-01)

containers-0.6 compatibility.

0.4 (2018-03-18)

GHC 8.4 compatibility.
Drop compatibility with GHC 7. GHC 8.4 introduces Semigroup as a superclass for monoid, and Semigroup is not in base prior to GHC 8. To avoid a conditional interface or a dependency on the semigroups package, we drop compatibility with GHC 7. There are not other changes in this version, so ixset-typed-0.3.1.1 remains usable with GHC 7.

0.3.1.1 (2017-08-14)

GHC 8.2 compatibility.

0.3.1 (2016-06-21)

GHC 8.0 compatibility.

0.3 (2014-07-23)

IxSet internals are now more strict
The empty method of Indexable is now called indices and has a slightly different path; to migrate your code, if you were using Template Haskell, you probably do not have to change anything. Otherwise, wherever you have an instance of Indexable that looks like this
```
 instance Indexable MyIndexSet MyType where  -- OLD
   empty = mkEmpty ...
```
change it to
```
 instance Indexable MyIndexSet MyType where  -- NEW
   indices = ixList ...
```
