OptiFine's latest development can be tracked on their official Discord server or social media accounts. On their server, they mentioned that the mod for 1.21.9 is 90% complete. They are currently fixing some bugs before releasing a stable version for The Copper Age game drop.

The main reason why OptiFine has not yet started working on 1.21.10 is that it is a hotfix update for Java Edition, released by Mojang a few days after The Copper Age game drop release. The Minecraft 1.21.10 fixes a few small bugs that crept up after the 1.21.9 release on September 30, 2025. Hence, the modding team is focusing on 1.21.9 first.

On OptiFine's website, the developers have released a preview version for the 1.21.9 game version. However, there are no 1.21.10 compatible mods.
