Hi all - we've released a fourth release candidate for Riot 1.6 at http://riot.im/staging, incorporating lots of feedback and bug reports from last week's RCs. The more you help test cross-signing & E2EE search (via http://packages.riot.im/nightly) the sooner we'll be able to ship! :D
I started working on cross-signing in @Matrix.org with the initial spec proposal submitted in September 2018. Over a year and a half later, it's nearly ready to go live in Riot.im. We had a video-conferenced key-signing party today at work, which involved us yelling emoji over each other. It's nice to have people stress-testing something that you've worked on for so long, and have it hold up.
Lots of new homeserver development happening atm - between Dendrite having implemented V2 state res, Conduit rising from Ruma's ashes, and Maelstrom forming too! So no better time to publish a new guide for understanding V2 state res from @email@example.com: https://matrix.org/docs/guides/implementing-stateres
