It's been a busy time of business growth, marketing, sales, etc... but I'm working today and tomorrow on finishing what remains for this beta series, completing testing, then releasing the new final build. We're about 30 days from the last final build, so it's not like it's been a long time, just seems like it to those waiting for X, Y, or Z. Some requests I may still not have got to, though will immediately begin with the next beta series that follows the final.
Generally speaking, there are times when development leaps forward, and times when it settles for a while to focus on sales, marketing, web site (notice the new site?), etc.. - this was one of those brief periods.
