KiCAD has come on a way since the last stable release, I do weekly updates from source on Windows, and it always seems to run fine, I have even made a few boards with a development release in May this year, no worries!
Eagle isn't dying, the latest release 7.3 wasn't that long ago.
As Bassman said, there is a new stable release in the next month or so.
Libraries can be difficult sometimes to produce with a package, because there are so many,you can't tailor them all, which is why the likes of Altium have a footprint wizard built in, and you can also get these multi tool PCB library editors based on IPC, your best bet is to start creating your own libraries.
