Details

Languages & speech

• French (fr) — new
• Greek (el) — new
• Hungarian (hu) — new
• Polish (pl) — new
• Russian (ru) — new; speech changes merged (#689)
• Norwegian (nb) — speech + navigation enhancements; navigation zoom no longer says “in” for prefix/silent intents (e.g. “b” instead of “in b” for -b)
• Swedish (sv) — translation update (#682); same navigation zoom fix as Norwegian
• German (de) — digit rules, units, and other speech fixes; set grammar; unit plurals and definitions; absolute-value ending; integral/logical symbols; “ray” → “Strahl”; “ruthe” → “Rute”; inverse grammar fixes
• Traditional Chinese (zh-tw) — navigation / related rule updates; translation refresh from English (2026-06-15 baseline, #618)
• English — core concept names (#381); principal Log vs log; identity / augmented matrices; black circled Latin letters; circled-number support; unit-definition cleanups
• Navigation rules — initial multi-language translation of navigation command names
• Cross-language — column and row separator announcements in matrices/tables (#679); multi-line script positions (mtable or nested munder/mover) separated by commas; uptack (⊥) speaks as “perpendicular” (#330); non-terse square root speech restored (#668); lg recognized as ASCIIMath function; better speech for missing/parse-error characters
• Intent — inference tweaks; richer definitions.yaml format with | alternatives; intents aligned to core concepts with tests

Braille

• Russian — new
• French braille — new braille code with rules, unicode tables, and chemistry tests (initial release; some open questions remain)
• Nemeth — 2022-oriented updates (ellipses, multipurpose between scripts, currency, typeform prefs cleanup, bugfixes); fixed braille for ⋄ (diamond operator, #703)
• UEB — updated to latest BANA/ICEB guidance:
  • Grade-1 indicator rules revised; new G1 BANA/GTM mode preference
  • Expanded grade-2 contractions; fixed be / con / dis contractions at word starts
  • mtable row-start and row-terminator handling for linear braille (some rules provisional, pending ICEB feedback)
  • New accented-letter patterns (e.g. Ñ) and Hebrew alphabet indicator
  • Narrowed overly broad pseudo-script rule (also cleaned up in other braille codes)
• Unicode tables — collapse to ranges + range fixups
• Refactor — BrailleCode trait + registry
• Table-related braille/rules work
• Remove incomplete ASCIIMath-fi packaging that broke builds

Canonicalization, chemistry, robustness

• Chemistry — mmultiscripts/scripts merge, atomic-number scoring and lookup table, chem-element intent/heuristics, chem test fixes; prescripts matching atomic number boost chemistry detection; primes on chem symbols (e.g. R') no longer rejected
• Arc-like symbols — merge under restricted conditions (#698); arc look-alike chars fixed after canonicalization change
• Bad mmultiscripts / empty bases / data-split cleanup
• Currency symbols split out of mtext / mi / mn; less aggressive ? fill-in
• Empty <mi> / degree edge cases; mtext-as-number → mn where appropriate
• Stronger panic/error reporting (tests + containers)
• SSML — stopped incorrectly escaping SSML (#585)

Internals

• Rust edition 2024; lazy_static → LazyLock; API cleanups (AsRef<str>, etc.)
• anyhow instead of error-chain
• Optional no-unsafe via sxd-document-no-unsafe / sxd-xpath-no-unsafe (default = classic mode)
• Rules packaging — unified Rust package-rules for CI, include-zip, and release zips; Rules-minimized.zip (flow-style YAML) for smaller downloads
• CI — build/test/clippy for default and no-unsafe; fuzz both configs; CI on all branches and PRs; Python tooling CI; coverage; pre-release fixes
• cargo-fuzz harness, dictionary, corpus cache, regression helpers
• audit-translations and related Python/uv tooling; new --exclude option with tests
• Parallel tests — serialized rules unzip/YAML reads to avoid races

Docs

• README / product-page copy; AT notes (JAWS, Orca, Kurzweil, etc.)
• User guides / translators’ guide work; example HTML for translator testing
• New logo with hi-DPI rendering, dark-mode contrast pill on many pages.
• User guide and translator’s guide revisions; updated acknowledgements; MathCAGT demo link in developer docs
