Preserving model outputs during optimization
Folding BatchNorm into Gemm ignored Gemm’s beta coefficient, changing the output of optimized ONNX models. The fix includes beta in the fused bias and adds parameterized regression coverage.

Filesystem events on Windows
Renaming a file to a different case made Windows report a deletion that never happened, so anything watching the folder saw a file vanish and come back. The false event is coalesced away now.
Rank correlation that depended on row order
Whenever two values tied, the same paired data gave a different answer depending on the order the rows arrived in. Ties now share an average rank. Three further fixes followed, including line endings that broke linting on a fresh Windows clone.
Paths that were not plain ASCII
Three fixes to a film-negative tool. The Windows updater broke on any profile path containing a non-ASCII character, script generation assumed POSIX paths, and the tests read source files in whatever codepage the machine happened to use.
