haskell-gi-0.20.3: ChangeLog.md

### 0.20.3

+ Make the overloading code protected by a CPP conditional, depending on ENABLE_OVERLOADING being defined. See [issue 107](https://github.com/haskell-gi/haskell-gi/issues/107).

+ Wrap boxed structs/unions as transient [ManagedPtr](https://hackage.haskell.org/package/haskell-gi-base/docs/Data-GI-Base-BasicTypes.html#t:ManagedPtr)s in callbacks. This is needed to fix a number of issues, including [issue 96](https://github.com/haskell-gi/haskell-gi/issues/96) and [issue 97](https://github.com/haskell-gi/haskell-gi/issues/97).

### 0.20.2

+ Fixes for GHC 8.2.1.

### 0.20.1

+ gtk-doc parser and haddock generator: while by no means perfect,
now the autogenerated bindings come with some reasonable
autogenerated documentation.

+ Many bugfixes. A particularly important one is for
[issue 82](https://github.com/haskell-gi/haskell-gi/issues/82), which
made compilation of
[gi-glib](http://hackage.haskell.org/package/gi-glib) fail, for
the latest version of gobject-introspection.
