[QGIS-Developer] Build new plugin in QGIS 2 or QGIS 3?

[Phil Ribbens]

Hi,

Should I build a new plugin in QGIS 2 or 3? 

I've been tasked with building a new plugin, but given that QGIS 3 just came out I’m not sure whether I should build it in QGIS 2 or 3. 

Basically, the plugin will:
1) clip/extract a raster layer by a vector/polygon layer
2) combine that clipped/extracted raster with some additional data (from a csv I think), resulting in an output of new raster dataset(s) and one large data table

A little more background:
	- I’m pretty much brand new to QGIS (if you haven’t noticed by now :)). I have downloaded both 2.18 and 3 and played around with them a bit, but I’m still pretty new to it all.
	- I do have some programming experience (including some, although not a ton, with Python).
	- I’ll be using a Mac
	- I'm hoping to have the plugin ready by sometime in July 
(also, in a related note, am I crazy to have signed on to do this?)

Thanks for any help you can provide,
Phil Ribbens
