## New Features * Iris 1.8+ * Iris 1.8 removed support for negative block IDs, which were previously used by RenderPearl * The update also added [additional shadow programs](https://github.com/IrisShaders/Iris/issues/2441) and [the ability to disable sky and star rendering](https://github.com/IrisShaders/Iris/issues/2470), which are now used by RenderPearl to improve performance * Light index-based lighting now enabled by default! * Due to significant improvements to the structure of the shader pack as well as the lighting calculations and culling, both Colored Light and Glossy Reflections are now enabled by default * Implicit surface smoothness & improved specular map support * When specular maps are disabled, smoothness values are automatically generated based on surface luminocity. More customization of this feature will be available in the future * Completely custom sky rendering * Significantly faster than the Vanilla Minecraft sky * Still slightly unstable and **may not look right all the time**, which is part of why this release is marked as a beta * Hand Light option ## Improvements * Compute-based post-processing and deferred rendering * This significantly improves performance in many situations due to less unneccessary processing, fast shared memory and asynchronous processing * Translucent terrain is still forward rendered using a technique similar to that in RenderPearl v2.1, though this is subject to change * Fog can now be disabled (requested by Baldous_) ## Fixed Issues * Enchantment glint is broken in the nether (reported by Stonease) * Light Level Visualization is incompatible with some drivers (reported by Paragoumba)
