Proposal to use this thread as a place to stay up to date with XCM development.
Considering a lot of new developments happening, XCMv3 hopefully being around the corner, and a XCM rebranding being in progress - teams building on Polkadot need a place where they can stay up to date with everything that is going on.
Github PRs are great for tech teams - but a simplified digest in a single place would significantly improve transparency. This also helps us explain and defend XCM in the public, when compared to IBC and other cross-chain protocols.
Calling Parity to kindly post an update here once in a while, and welcoming everyone to share resources (e.g. comparisons with other protocols, external reports about XCM, etc.) that might be useful for the community.
