quill 1.4.2 — 2026-09-30
  Fixed: CJK runs now wrap at the width edge without requiring spaces;
         mixed CJK/Latin paragraphs no longer overflow on narrow -w.
  Added: --join-blank to reunite paragraphs that an author (or an old
         export filter) hard-wrapped with blank lines every N words.
  Fixed: trailing spaces could survive on wrapped continuation lines.
  Tests: battery extended for CJK and hard-split paths.
  Note:  1.3.x (LTS) intentionally does not receive --join-blank.

quill 1.4.1 — 2026-05-11
  Fixed: width below 20 is rejected with a usage error instead of
         producing single-character lines.

quill 1.4.0 — 2026-02-03
  Changed: paragraph model tightened — a paragraph is exactly a run of
           non-blank lines; multiple blank lines collapse to one.
