[QGIS-Developer] Python question: QgsVectorLayer object has no attribute 'pendingFields'

[Etienne Trimaille]

While I'm porting my plugin, I'm usually opening this doc
https://github.com/qgis/QGIS/blob/master/doc/api_break.dox

Then I search for every new exception I have, I often find a solution there.

> pendingFields is gone this morning: https://github.com/qgis/QGIS/pull/6050
> Maybe just use `fields()` ?
