aniread 0.4.1

New features

• read_octron() gains a properties argument for picking which region-property columns to read ("all" by default; pass a character vector for a subset or NULL to skip them). area is auto-included when method = "weighted".
• read_octron() normalises hyphens to underscores in column names (moments_hu-0 → moments_hu_0).

Performance

• read_octron() is now substantially faster on large multi-segment files, especially when only a few properties are requested.

Bug fixes

• read_octron(method = "weighted") no longer silently recycles v * a when a row's value and area columns have different segment counts; it falls back to the arithmetic mean for those rows and emits a single warning naming the affected frame_idx values.
