In the past, I've emailed my team to alert them to manual updates, new Q&A responses, and blog posts. I thought these summaries might help some other teams, as you could check this one thread instead of many other places, and figured I might as well post them since I'm already writing them.
I usually try to post each time a new manual update comes out, unless there's a really important Q&A response. Disclaimers that I may not always be this frequent, and that although I try to ensure summaries (Q&A responses in particular) are accurate, I have made mistakes, and always check the official update/response. Also, I'll link to all the relevant CD threads for blog posts/updates/etc. and would appreciate it if discussions could stay there to avoid confusion, although corrections are always welcome here.
