What's new in 3.9.2

This release adds token_fix, a rule-based component that runs after senter to repair sentence boundaries around punctuation that the statistical model mis-splits. It is bundled with the model and registered automatically as a spaCy factory, so spacy.load("la_senter") activates it with no extra imports.

• Parentheticals — a ! or ? inside (...) or [...] no longer ends the sentence: Verba (mirabile dictu!) sunt. stays one sentence.
• Dash asides — the same for em/en/hyphen-delimited asides: Nostraque — me miseram! — timui. stays one sentence.
• Orphaned closing quotes — a sentence-final closing quote is kept with its sentence rather than split onto the next: "Ita est." "Dixit." breaks after the first closing quote, not before it.

3.9.1

Internal development version — first bundled the fixers but was never published to HuggingFace; superseded by 3.9.2 (which corrects the component registration and aligns the version with the latincy-pipelines releases).

What's new in 3.9.0

• Case-insensitive segmentation: correctly handles lowercased and mixed-case input
• Sentence splitting on semicolons and colons
• Bracketed reference handling: [2] O tempora... is treated as one sentence

Training

Trained on five Universal Dependencies Latin treebanks using spaCy's senter component.
