[Qgis-developer] Change vector layer data source

[Andreas Neumann]

Hi,

I am working on the Visual changelog for QGIS 2.10 and I came across 
http://changelog.qgis.org/qgis/2.10/entry/allow-changing-vector-layer-data-source/update/

However, this does not work for me, or I can't figure it out how to 
change a vector data source.

Also - does it only work for files or also for database sources?

Could someone please explain how this works?

Thanks,
Andreas

PS: could someone please accept my entries so that they appear in the 
public list?
