gi-vte-2.91.19: ChangeLog.md

### 2.91.19

+ Properly annotate the return value of [terminalGetWindowTitle](https://hackage.haskell.org/package/gi-vte-2.91.19/docs/GI-Vte-Objects-Terminal.html#v:terminalGetWindowTitle) as nullable.

### 2.91.18

+ Properly annotate the return value of [terminalGetCurrentDirectoryUri](https://hackage.haskell.org/package/gi-vte-2.91.18/docs/GI-Vte-Objects-Terminal.html#v:terminalGetCurrentDirectoryUri) as nullable.

### 2.91.17

+ 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).

### 2.91.13

Do not generate code for Terminal.event_check_regex_simple, since it has wrong introspection data.
