Yes the updates will continue. The missing months will likely be captured as part of a larger 'round up' update as we resume. A lot of work has gone into things that, from a user's perspective, are pretty much done (themes, stacks, etc). We have some nice updates to moderator tooling coming out, and some more results and tweaks to talk about for the question wizard soon.
There's an interim sort of product manager that's keeping things we've already got scheduled moving, and we will have at least one new PM starting next month, but we can probably put out an update between now and then. Thanks for pointing out that we hadn't, I'll get with folks heading that up and see about getting something written.
Note, again, expect a lot of 'finishing touches' kinda stuff, but we'd rather bore you than keep you waiting :)
These should resume before the end of this month (February 2019). There will likely be some additional posts about the ask question wizard and moderator tools that, while falling into the category of the round-up I was referring to, really should be broken out on their own. But, we'll reference those posts in the cumulative update.
Then, the update process will continue as announced until we find some way of tying the back-end stuff to the front-end stuff so you can just do a cursory search to get an idea of what's being worked on or recently marked completed.
