As T139254#2425734 and T139181 made clear updates to our Phabricator installation are not communicated to the community. I'm not saying all of them should be but the example issue made a fairly large change and I can't have been the only one wondering why I suddenly had lots of "added substask" in my history which I never remembered doing.
- Tech News
- The Phame blog embedded in our Phabricator.
- Some mailing list
If there is a mailing list for this already... Then maybe document it on the starting page... and still consider communicating larger changes wider?
