26.2.0

• Added statsutils.mode to return the most common value, breaking ties by first appearance (#453)
• Fixed setutils.IndexedSet.update adding the iterables themselves instead of their elements when given multiple inputs (#474)
• Fixed strutils.iter_splitlines and strutils.indent splitting dates containing 28 or 29 instead of recognizing Unicode line separators (#475)
• Added strutils.ellipsize for word-boundary-aware text truncation with an ellipsis
• Fixed funcutils.wraps passing arguments positionally to wrappers that only accept them as keywords (#261)
• Fixed tableutils.Table.to_text crashes on empty tables, None headers, and short header rows; empty headers now render no header row, matching to_html
• Fixed timeutils.isoparse misreading fractional seconds (.851 parsed as 851µs instead of 851000µs); >6-digit fractions now truncate instead of raising
• Fixed timeutils.daterange looping forever on non-advancing steps: zero and self-cancelling month/day steps now raise ValueError, wrong-direction steps yield nothing like range()
• Fixed strutils.MultiReplace raising KeyError on empty substitution maps (now a no-op)
• Fixed jsonutils.JSONLIterator hanging when a seek lands past the last newline, and negative rel_seek values seeking past EOF (sign bug)
• Fixed iterutils.xfrange yielding nothing for descending ranges; now shares frange's count-based semantics, so both agree at inexact float boundaries
• Fixed urlutils.parse_qsl ignoring its encoding argument when decoding keys and values (#455)
• Fixed dictutils.OrderedMultiDict.addlist dropping values from one-shot iterables, including the vendored copy in urlutils (#458)
• Fixed ecoutils.get_profile looking up identifying host, username, and working-directory information when scrub=True (#461)
• Fixed namedutils.namedtuple and namedutils.namedlist raising IndexError instead of ValueError for empty type and field names (#462)
• Fixed iterutils.GUIDerator error text to reflect the inclusive minimum size of 20 (#451)
• Fixed timeutils.decimal_relative_time and relative_time rejecting aware datetimes when the comparison time is omitted (#469)
• Fixed timeutils.USTimeZone handling of repeated and missing DST hours, including fold on UTC conversion (#441)
• Fixed mathutils.Bits negative indexing (#450)
• Fixed mathutils.Bits empty binary, hexadecimal, and byte round trips (#468)
• Sped up setutils.IndexedSet bulk difference and intersection updates with a single-pass rebuild (#440)
• Fixed listutils.BarrelList out-of-range indexing returning unrelated values (#440)
• Fixed listutils.BarrelList insertion clamping across multiple internal lists (#440)
• Fixed listutils.BarrelList popping after an internal list was emptied by indexed removals (#440)
• Fixed listutils.BarrelList.iter_slice slice normalization and reverse steps (#471)
• Fixed listutils.BarrelList.del_slice deletion across internal lists and through the end of the list (#472)
• Fixed jsonutils.JSONLIterator rejecting the documented rel_seek=1.0 endpoint (#465)
• Fixed jsonutils.JSONLIterator relative seeking in binary streams (#464)
• Fixed statsutils.Stats.get_histogram_counts division by zero for data with no interquartile spread (#467)
• Fixed jsonutils.reverse_iter_lines ignoring explicit and stream encodings (#463)
• Fixed jsonutils.reverse_iter_lines detaching the caller's text stream, preventing later reads and context-manager cleanup (#466)
• Fixed cacheutils.ThresholdCounter.update ignoring mapping and keyword counts (#476)
• Fixed cacheutils.LRI.update and 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 returning no pairs when the limit is omitted (#460)
• Fixed strutils.bytes2human failing to use the Y suffix for yottabyte-sized values (#459)
• Fixed urlutils.URL.get_authority dropping passwords when the username is empty (#477)
• Fixed strutils.args2sh and strutils.args2cmd ignoring the sep argument (#454)
• Fixed statsutils.Stats.pearson_type raising RuntimeError instead of classifying Pearson types IV, V, and VI (#434)
• Fixed statsutils.Stats.pearson_type division by zero at the exact coefficient boundary, preserving the existing Normal and Gamma cases (#434)
• Fixed setutils.complement subset and superset comparisons raising AttributeError (#438)
• Fixed mathutils.Bits accepting values too large for the requested bit length
• Fixed tbutils.ParsedException dropping Python 3.11+ traceback anchor lines during round trips (#333)
• Fixed strutils.pluralize handling of words ending in x, such as box
• Fixed iterutils.backoff_iter division by zero with factor=1.0 and no count; equal bounds yield once, and unequal bounds raise ValueError
