Matrix.org Foundation announced the release of Matrix 2.0, built on four key enhancements. Simplified Sliding Sync (MSC4186) makes login and sync near-instant and runs natively in Synapse since 1.114, so the separate Sliding Sync Proxy is on its way out. Native OIDC (MSC3861) hands login to an OAuth 2.0/OpenID Connect provider, so your password only ever reaches the auth server. MatrixRTC (MSC4143) brings end-to-end encrypted group voice and video calls into Matrix itself instead of leaning on Jitsi. Invisible Encryption (MSC4153) starts by excluding devices that are not cross-signed from getting room keys. All four proposals have since been accepted, MatrixRTC only in October 2026, so “here” took a while.
As for client software, currently only Element X supports Matrix 2.0. Element’s launch post makes Element X the mobile app most Element users should now use, and notes that a login you cannot verify from another session or with your recovery key means resetting encryption, which deletes the server-side key backup. So keep that recovery key somewhere you will actually find it.
