sgolay 1.0.4 (2026-07-09)

• Fix a crash on R >= 4.3 in sgolayfilt() when a plain (unclassed) filter coefficient matrix is passed as p (dim(p) > 1 errored inside && for any matrix; replaced with is.matrix(p)).
• sgolayfilt() now validates that a custom filter coefficient matrix p has an odd number of rows, instead of silently producing incorrect boundary values.
• sgolayfilt() now errors with a clear message when x is shorter than the filter length, instead of an obscure “subscript out of bounds” error.
• Added regression tests for the “auto” engine’s filter-length threshold and the fft-to-filter NA fallback.

sgolay 1.0.3 (2023-03-30)

• Fix warning on bitwise comparison in my_isok() macro
• Fix lossy conversion on indices from long to int
