Mellow

• Added a new cloud style: "Blocky"
• Made POM work on blocks with rectangular faces (eg. fences, stairs). POM should be a little more performant too.
• Handheld lights are now centered around the player in 3rd person (iris exclusive)
• Added dynamic image sharpening, which should reduce artifacts when stading still with the "Fabulous" profile
• Made daytime slightly less bright
• Small optimizations for bloom, shadows & lighting
• Fix outline effect appearing on the edges of the screen
• Fix puddles appearing in the nether & end
• Fix "Water Fog" & "Underwater Fog" options
• Many other bugfixes

• Added water puddles after rain option
• Added displacement around grass when the player walks through it
• Added PBR resourcepack reflections
• Fixed specular highlights being too weak
• Added POM shadowing option
• Small tweaks to existing effects
• Lots of changes under the hood, that should allow for more cool effects in the future!

• Added rainbows. By default, they appear after rain
• Added support for PBR porosity & SSS
• Slight improvements to ambient occlusion quality
• Added a few customization options: border fog falloff, selection outline color
• Fix particles not being lit up by handheld lights
• Fix fog being weaker in older game versions
• Fix custom skyboxes in the end
• Fix image sharpening running in the wrong color space
• Small optimizations

• Rework ambient fog & underwater fog. It should look much nicer and behave better with Voxy & DH
• Added POM for labPBR resourcepacks
• Changed clouds shape to feel more "clumped". Clouds should be a bit more performant too
• Optimized raytraced reflections & ambient occlusion
• Add two new tonampper options: AgX Punchy and Khronos PBR Neutral (by @Notritsu)
• For the billionth time, changed how water transitions into DH terrain

• Fix distant horizons rendering
• Added a new style of clouds: Volumetric
• Fix some bugs with distant horizons & voxy on older game versions
• Fix water, end sky, not renering behind the block selection outline
• Fix flipped image reflections with voxy

• Fix block breaking animation
• Fix flipped image reflections with voxy
• Optimized depth of field effect & made it work with lod mods
• Fix seasons with voxy

• Fix compilation error with voxy mod on nvidia hardware
• New end portal effect
• Fix incorrect translucent rendering with voxy

Dynamic Shadows

• This should bring mellow more in line with other shader visually
• While I optimized them as much as I could, they still cost a lot of performance. This is why they are off by default. This might change in the future though.
• You can enable them in the shader settings. I put them right on the front page!

Voxy support

• Voxy is a mod that renders far terrain using lods, with higher detail than Distant Horizons. Mellow now supports it.
• This feature is experimental. Expect some bugs.

Colorwheel support

• This mod gives higher performance with Create and shaders. Mellow now supports it.

PBR support

• Added support for labPBR 1.3 resource packs. Once again, this is off by default for performance reasons
• Normals, specular reflections, texture AO, emissiveness and SSS are supported

More cool effects

• Added chromatic aberration
• Added color balancing options
• Added a channel mixer option
• Added a world outlines option

Season coloring

• Added on option to change the color of foliage based on seasons
• Each season lasts 30 minecraft days, A new world starts with spring

Other

• Switched to glsl version 400. This allows me to write cleaner code, and use advanced functions for more performance (in the future)
• Added settings for border fog and underwater fog strength
• Fix z-fighting on banners and texture overlays
• Improve the aspect of terrain from lod mods with SSAO
• Improved aspect of handheld lighting
• Fix some other minor bugs
