He may have got busy I haven't seen him on here in awhile (geekmug, I think on these forums). I think in an earlier post DataGhost said when he completes the 1.01b he may have a look at the 1.01a. I luckily have 1.01b on my S5.
Don't forget though, these guys do this for free when they have time to do it. He might have gotten busy with work, family or just don't feel like programming for awhile. I hope I can learn enough to eventually contribute to such efforts, but until then, I have to be patient and thankful that they do this to begin with.
