Protect Poutu-te-rangi

Release

v1.1.3 -- Protect Poutu-te-rangi -- is minor version with additional critical Altair test vectors but with zero substantive changes to the Altair specification.

🙌 Huge shoutout to @potuz for identifying a series of critical Altair fork transition tests that were missing in the consensus vectors 🙌

All clients should run these test vectors immediately!

Additionally, there is iterative progress on Merge specifications. For current Merge interop, please continue to target v1.1.2. We'll batch Merge changes at the end of the month for a new interop target.

Astraios

Release

v1.1.2 -- Astraios -- is minor version release that fixes some of the Altair and Merge test generators. All core specifications remain stable, but due to the additional Altair test vectors, it is critical that clients build and run these additional tests as soon as possible.

Release

v1.1.1 -- Is it an Ocean or a Sea? -- is minor version release focused on a couple of critical fixes to Merge interop specs (#2634, #2640).

Additionally, beacon state initialization for pure Altair testnets is modified with a minor fix. This does not affect Mainnet or any current testnet instantiations.

The Great Machine

Release

v1.1.0 -- The Great Machine -- is the mainnet release of Altair specs, including the epoch chosen for the planned mainnet upgrade on Oct 27, 2021 (#2625). This marks the first major upgrade to the Great Machine since genesis in late 2020.

Merge interop specs remain stable from v1.1.0-beta.5 other than the addition of the terminal blockhash override (#2617) [not required for initial interop] and some new consensus tests (#2630). Due to the inclusion of additional consensus test vectors, we recommend targeting v1.1.0 tests prior to initial interop.

KIC 9832227

Release

v1.1.0-beta.5 -- KIC 9832227 -- is a minor release in preparation for initial Merge interop 🏺. Although we still expect much refinement and testing of specifications in the coming months, Merge specs have matured so that client teams now have a stable target.

Huge shoutout to @mkalinin and the many other contributors that have worked so hard getting the Merge specs into clean place for the next wave of engineering 🙏

Altair specifications remain entirely stable and are slated for a mainnet release in the coming days.

The Chandrasekhar Limit

Release

v1.1.0-beta.4 -- The Chandrasekhar Limit -- is a minor release that focuses on expanded test coverage (again!), along with a couple of minor iterations on the Merge spec.

Warning: To facilitate the testing of the scaled validator churn limit while avoiding the use of a >300k validator set, minimal config has been altered to reduce the CHURN_LIMIT_QUOTIENT. To our knowledge, minimal is not currently used for any testnets so shouldn't cause much issue, but be careful to port the config update to your testing infrastructure.

Moon Rock Market

Release

v1.1.0-beta.3 -- Moon Rock Market -- is a minor release that focuses on expanded Altair test coverage, along with major improvements and refinements to the Merge and Sharding specs.

Massive shout-out to @ralexstokes for creating a framework for massively increasing block transition test coverage (#2567) 🐳💪

The Merge has been rebased on both London (#2533) and Altair specifications (#2530), and is now equipped with a first iteration of the p2p spec (#2531). With these core elements in place, the consensus Merge specs are ready for their next wave of client development.

Sharding saw a major redesign in its data market through the separation of block producers and builders. This shifts the economic responsibility of network data availability into the hands of well-incentivized, specialized actors called "builders". This aids in the democratization of shard-data MEV, reduces the bandwidth of data-tx gossip, and eases networking assumptions/requirements for validators. Nice work on this @protolambda 🙌
