What's new

Lost Signal VHS v1.8.1 — Critical Packaging Hotfix

Fixed
• Iris can now discover the required shaders/ directory.
• Windows-style backslash entry names were replaced with standard portable ZIP paths.
• Automated release validation now checks shader entry points, geometry fallbacks, localization files, unsafe paths, and invalid separators.
• Every v1.8 Analog Fog feature and preset is retained without shader-code changes.

Important: v1.7 and v1.8 were packaged incorrectly and may be rejected as invalid by Iris. Please update to v1.8.1.

Live verified on Minecraft 26.2 with Fabric Loader 0.19.3, Iris 1.11.2, Sodium 0.9.1, NVIDIA RTX 5070, and OpenGL.

Primary targets: 1.20.1, 1.21.1, 1.21.4, 1.21.11, 26.1.2, 26.2.
Extended compatibility targets: 1.18.2, 1.19.4, 1.20.4, 1.20.6, 1.21.5, 1.21.8, 1.21.10. These targets have not all been live-tested across every loader/GPU/driver combination.

Minecraft 26.x requires Iris with OpenGL; do not use the experimental Vulkan backend.
