(September 7, 2026)

• Added [statsutils.mode][statsutils.mode] to return the most common value, breaking ties by first appearance (#​453)
• Fixed [setutils.IndexedSet.update][setutils.IndexedSet.update] adding the iterables themselves instead of their elements when given multiple inputs (#​474)

• Fixed [listutils.BarrelList][listutils.BarrelList] out-of-range indexing returning unrelated values (#​440)
• Fixed [listutils.BarrelList][listutils.BarrelList] insertion clamping across multiple internal lists (#​440)
• Fixed [listutils.BarrelList][listutils.BarrelList] popping after an internal list was emptied by indexed removals (#​440)
• Fixed [listutils.BarrelList.iter_slice][listutils.BarrelList.iter_slice] slice normalization and reverse steps (#​471)
• Fixed [listutils.BarrelList.del_slice][listutils.BarrelList.del_slice] deletion across internal lists and through the end of the list (#​472)
• Fixed [jsonutils.JSONLIterator][jsonutils.JSONLIterator] rejecting the documented rel_seek=1.0 endpoint (#​465)
• Fixed [jsonutils.JSONLIterator][jsonutils.JSONLIterator] relative seeking in binary streams (#​464)
• Fixed [statsutils.Stats.get_histogram_counts][statsutils.Stats.get_histogram_counts] division by zero for data with no interquartile spread (#​467)
• Fixed [jsonutils.reverse_iter_lines][jsonutils.reverse_iter_lines] ignoring explicit and stream encodings (#​463)
• Fixed [jsonutils.reverse_iter_lines][jsonutils.reverse_iter_lines] detaching the caller's text stream, preventing later reads and context-manager cleanup (#​466)
• Fixed [cacheutils.ThresholdCounter.update][cacheutils.ThresholdCounter.update] ignoring mapping and keyword counts (#​476)
• Fixed [cacheutils.LRI.update][cacheutils.LRI.update] and [cacheutils.LRU.update][cacheutils.LRU.update] rejecting empty and keyword-only updates, and ignoring keywords when the source is the cache itself (#​478)
• Fixed [cacheutils.ThresholdCounter.most_common][cacheutils.ThresholdCounter.most_common] returning no pairs when the limit is omitted (#​460)
• Fixed [strutils.bytes2human][strutils.bytes2human] failing to use the Y suffix for yottabyte-sized values (#​459)
• Fixed [urlutils.URL.get_authority][urlutils.URL.get_authority] dropping passwords when the username is empty (#​477)

• Fixed [statsutils.Stats.pearson_type][statsutils.Stats.pearson_type] raising RuntimeError instead of classifying Pearson types IV, V, and VI (#​434)
• Fixed [statsutils.Stats.pearson_type][statsutils.Stats.pearson_type] division by zero at the exact coefficient boundary, preserving the existing Normal and Gamma cases (#​434)
• Fixed [setutils.complement][setutils.complement] subset and superset comparisons raising AttributeError (#​438)
• Fixed [mathutils.Bits][mathutils.Bits] accepting values too large for the requested bit length
• Fixed [tbutils.ParsedException][tbutils.ParsedException] dropping Python 3.11+ traceback anchor lines during round trips (#​333)
• Fixed [strutils.pluralize][strutils.pluralize] handling of words ending in x, such as box
• Fixed [iterutils.backoff_iter][iterutils.backoff_iter] division by zero with factor=1.0 and no count; equal bounds yield once, and unequal bounds raise ValueError
