@joepie91 Do we have a source for this?
From what I can see (https://matrix.org/_matrix/federation/v1/version) they run a version that identifies itself as 1.121.0rc1 (b=matrix-org-hotfixes,0fb2633a27) and that's available on https://github.com/element-hq/synapse/commits/matrix-org-hotfixes/ (one of the commits there is indeed 0fb2633a27).
@Peetz0r It was apparently mentioned in a recent Matrix Live, and came up in a TWIM room
@Peetz0r Because money, it seems. Kind of the predictable outcome of their high-spend approach to protocol development (which I'd already warned them about before but they were *sure* wasn't going to be a problem)
