0.1.0 (06/30/2022)

Initial Commit

0.2.0 (08/20/2023)

New Features

Add differentiable noise generator nodes
Support Pixel Processor and FX-map nodes
Support joint optimization of continuous and integer parameters
Support non-atomic function nodes

Enhancements

Improve the runtime of various filter nodes (particularly gradient map nodes)
Restructure codebase

Bug Fixes

Automatically rerun sbsrender using CPU SSE2 engine if the default engine fails to generate texture output (Issue #1)

0.2.1 (01/01/2025)

New features

Support LPIPS and L*a*b* color space metrics as optimization objectives
Support line search optimizers
Add control over the range of saved data during optimization

Enhancements

Any unsupported/legacy material node types and their preceding subgraphs are frozen during optimization instead of triggering translation errors
Intermediate results during the forward evaluation of material graphs are discarded by default to reduce VRAM consumption
Material nodes now actively report errors on missing required input connections

Bug Fixes

Fix the copying of custom dependencies before generating external input textures using SAT
Correct the translation of certain unsigned integers into negative integers
Miscellaneous minor fixes in material and function node implementations
