The changelogs are currently being added, and some versions are missing.
Today we are releasing 1.21.4 Release Candidate 2 to activate Blending around the Pale Garden Biome.
If no further critical issues surface, this is the version we are planning to ship as Minecraft: Java Edition 1.21.4.
Happy Mining!
