[Qgis-developer] API break

Hi all,

I noticed an API break has been introduced after 2.2:

2.2: void QgsSingleSymbolRendererV2::startRender( QgsRenderContext& 
context, const QgsVectorLayer *vlayer );
2.3: void QgsSingleSymbolRendererV2::startRender( QgsRenderContext & 
context, const QgsFields &  fields );

I was using this in a plugin to determine if a feature was rendered or not.

This was introduced by Martin for multi-threading

Although I believe that for such a change, some breaks were acceptable. 
Anyway, it would be nice to have this documented at some place. If it 
is, I did not find it.
