+# Iris 1.6.5 Changelog
+
+- Fixed NEC/Sodium screen bypass not working
+- Moved the "Color Space" toggle to Quality options.
+- Added `entity_flame` special ID.
+- Fixed a crash with core profile shaders.
+- Fix mismatched push/pop when in spectator on some packs.
+- Added a fake vertex shader subsystem, to fix *extremely* old packs without vertex shaders.
+- Fixed fake entity shadows on some packs.
+- Fixed lightning bolts not taking on the correct entityId.
+- Enabled smooth triangle (not quad) shading.
+- Added `dimension.properties`.
+- Added `is_on_ground`.
+- Added support for armor trim detection.
+
+### dimension.properties
+
+When `dimension.properties` is added to the shader pack root, behavior relating to dimensions change.
+Iris will no longer resolve any dimensions for you, and you are expected to resolve you own.
+
+The syntax for dimension.properties is as follows:
+
+`dimension.folderName = dimensionNamespace:dimensionPath`
+
+*You can use `*` as a value to fallback all dimensions to.*
