Iris Shaders

Iris 1.2.5 is now available for download for Minecraft 1.16.5, 1.17.1, and 1.18.2 (with 1.19 coming soon), fixing a huge number of bugs and mod compatibility issues, massively improving performance with packs using depth of field, and improving performance in some CPU-limited scenarios.

We hope for this to be one of the last big bugfix releases before PBR (Iris 1.3.0). When we release PBR, we plan to drop support for 1.17.1, meaning that the Iris release supporting PBR will only support 1.16.5, 1.18.2, and 1.19. We hope this makes sense, because actively supporting 4 different Minecraft versions would just be too much with our current development team.

This release was developed by coderbot & IMS with additional help from Pepper.
