• The SDK constraint is now ^3.5.0, so the package resolves on older stable Dart releases. No API or behaviour changes.

• The LICENSE file is now the plain MIT text so pub.flutter-io.cn recognizes it; the pattern-file notices moved to NOTICE.md.
• The package ships example/example.dart.
• Hyphenator.cacheSplitParts, an opt-in bound-sharing cache of the parts split returns. Off by default: it retains each word's text a second time, cut up, in exchange for turning a repeated split into a map lookup.
• split allocates its result once at its final size, and marking a word no longer allocates a lower-cased copy of it to probe an empty exception map.
• Cached break offsets are retained in the narrowest integer width that holds them, rather than one tagged word each. They are still unmodifiable.

Initial release.

• Hyphenator, splitting words with a compiled TeX pattern set, with an LRU cache over the words it has already seen.
• Hyphenator.fromSource and TexHyphenationPatterns, compiling pattern file text into a trie held in flat typed arrays and shareable between hyphenators.
• HyphenLineBreaker, greedy width-aware line breaking driven by a caller supplied measurement function.
• DanglingWords, an allocation-free probe table of words to keep with the word that follows them.
• minifyTexPatterns, stripping a pattern file down to its \patterns and \hyphenation groups.
