Thanks Lex. 
Means the plugin can be built for use with a version of Geany that is
built for gtk3, as well as for a version of geany built for use with
gtk2.

What that means needs to be changed in the plugin is specific to the
plugin, if it was known it probably would have been done already,
thats what you need to figure out to port them.

Now I know :) . So all I have to do is build all the orphaned geany-plugin and see if their build is ok and test them individually so that they dont break in geany 1.24 (the latest from git). For time being I can take the ownership of the orphaned geany-plugins that I mentioned in the first mail, in that case do I have to modify the MAINTAINERS file and add my name and email id to it?

Thanks,
