Yes, it’s the 3rd new version of the android app, which is necessary to converge the ios and android apps together… to fix precisely the sort of stupid bugs which you were highlighting originally. Element X is the new app, which implements the new faster sync and is built for performance from the outset. Element R is an upgrade to the existing separate apps, which converges just the encryption on the new rust implementation, to minimise future encryption bugs by sharing the same code over all 3 platforms. In terms of fixing perf, the solution is to switch to the new sync API (which will be supported on both synapse and dendrite) and use the new client codebase. Synapse and Dendrite are relatively similar in performance in comparison. Synapse dev will continue; Dendrite dev will continue focusing on embedded servers. Dendrite is very close to being stable, and yes there will be migration guides.
