Couldn't say really. At the time of this post, there were still 13 reports assigned (in work) with another 17 awaiting community feedback on whether fixes were successful. This is per the
road map and
change log respectively. There's quite a few spin-off issues that came up as well and some are still in-work.
It seemed logical that Alpha-22 would be where BugBash-1 leaves off, but I haven't seen confirmation either way. Still seems like there's a good amount of meaningful work to be completed. As for the spring cleaning, it'll expand into summer and fall cleaning easily. We still have a lot of reports to organize ahead of any future BugBash/BETA activities.
By all means, keep the suggestions coming and help us find reports in need of action. For those leaving comments on Mantis directly, it would be helpful if you could attach the tag "updaterFollowup" tag to any past posts and new ones going forward that require attention. Those that prefer the forums can still leave feedback here as well. Everything helps.
