Mushin

v1.1.4 -- Mushin -- is minor version release containing no substantive changes to mainnet released Phase 0 and Altair specs. Instead this is an iterative (and breaking) release of Merge specs.

v1.1.4 serves as the stable target for the Kintsugi🍵 Merge development sprint in November 2021.

Warning: Additional minor releases might be made throughout if/when issues are discovered during the sprint.
