[Qgis-developer] Synergy of QGIS Enterprise and QGIS 2.0/Master branch

[Pirmin Kalberer]

Hi all,

There were some discussions about the relation of the recently announced QGIS 
Enterprise [1] and the upcoming QGIS 2.0 release.
QGIS Enterprise was born out of the needs of our customers for a stable QGIS 
branch with frequent bug fix releases similar to the Ubuntu LTS model. Almost 
all of the professional QGIS users we know, have many custom plugins in use. 
Some of these plugins are applications with 10'000's lines of code! So API 
compatibility has absolutly hightest priority for them.
That's the reason we branched 1.9 before the API break to give our customers 
most of the features of 2.0 but let them more time to migrate their plugins to 
the new API.
We fixed many major bugs reported by our customers and applied them also to 
QGIS master [3]. The QGIS projects benefits from this model directly, since it 
finances at least Marco working 100% on QGIS core development. And there are 
not only bug fixes flowing back into QGIS master, but also major performance 
improvements [2],[4].
We hope very much that we can carry on this synergy for the coming years and 
look forward to see you in Maptember to work together on QGIS 2.1!

Regards
Pirmin
