The next release of the js sdk is planning to bump the supported #matrix spec version to 1.5 or 1.6. This means it and as a result also Element Web will refuse to start on current versions of #conduit and #dendrite. This is an intentional decision resulting from a discussion between several SCT members.

I think that approach is bad and it should check for a range of supported versions instead of arbitrarily bumping the minor version to make the ecosystem move, but this is a heads up, that now is the time to contribute to both of those servers, if you use them and want to use the Element Web client on them going forward. (I already had my discussion with the SCT and I won't tell other projects, what they should do.)
