+### 4.0.16
+
++ The `ignoreHosts` argument of [`networkProxySettingsNew`](https://hackage.haskell.org/package/gi-webkit2/docs/GI-WebKit2-Structs-NetworkProxySettings.html#v:networkProxySettingsNew) was being represented as `Maybe Text`, but it should have been `Maybe [Text]`. This fixes [issue 154](https://github.com/haskell-gi/haskell-gi/issues/154).
+
 ### 4.0.15
 
 + Remove enable-overloading flags, and use instead explicit CPP checks for 'haskell-gi-overloading-1.0', see [how to disable overloading](https://github.com/haskell-gi/haskell-gi/wiki/Overloading\#disabling-overloading).
