The typo-retrieval layer now ships prebuilt matrices for all six full-feature languages, setup backfills them on existing installs, and the engine records how it armed - plus a weekly guard against stale extension pins. The Rust crate follows at 0.2.1.
release 14 September 2026 read the entry →
A 0.481 MB character bi-encoder now retrieves the twenty nearest vocabulary entries for a misspelling and the fastText full tier rescores them, with the layer wired end to end: registry v1.7.0 carries the artifacts, kotoshu 1.0.3 fetches them with one setup flag, and the Rust crate and WebAssembly package expose the same engine.
release 14 September 2026 read the entry →
gem install kotoshu now resolves a precompiled native platform gem on Linux, macOS, and Windows, so the Rust engine runs with no compiler toolchain, and the backend default became auto: use the native engine when it loads, fall back to pure Ruby when it does not.
release 12 September 2026 read the entry →
The gem now embeds the frozen Kelly frequency tiers, so a machine with a cold cache ranks suggestions exactly like the frozen conformance vectors, without any download, CI seeding, or dataset switch at cache expiry.
release 12 September 2026 read the entry →
Four new 5,000-pair dictionary-grounded typo corpora, a published per-tier error budget, one-click wrong-suggestion reporting in the playground, and a rebuilt Docker CI image.
12 September 2026 read the entry →
The coordinated 1.0 cut: the Ruby gem, @kotoshu/wasm, and kotoshu-server all reach 1.0.0 with the public surface frozen and the 2,630-vector Ruby==Rust conformance contract gated in CI on both sides.
release 10 September 2026 read the entry →
The baseline command now accepts directories and globs, ignores the personal dictionary, and skips the suggestion sweep, and check --baseline no longer generates suggestions for the occurrences it suppresses.
release 10 September 2026 read the entry →
A single language pack now carries the dictionary, the embedding tier, the vocabulary, and the bucket table, and one loadPack call turns one fetch into the complete set of engine handles.
release 10 September 2026 read the entry →
One fetch now loads a whole language through KPK1 packs for English, German, and Portuguese, and the typo-biencoder hybrid becomes the first alternative model to beat the full tier on every gate.
release 10 September 2026 read the entry →
The playground worker protocol ships on npm as createEngine, covering load, check, suggest-batch, semantic, and detect, with the same pinned resources, the same caching, and no install step.
release 9 September 2026 read the entry →
Model-generated candidates now reach out-of-vocabulary misspellings in 45 more languages, and eight languages were rejected on measurement with full evidence ladders.
release 8 September 2026 read the entry →
setup no longer gates on a module, so 95 staged languages work out of the box with script-aware fallbacks, and Korean and Nepali join the full-feature 35.
release 7 September 2026 read the entry →
Detection prefers the lid-176 model through the gem 0.10.0 native path, and the engine field reports which detector served the answer.
release 7 September 2026 read the entry →
kotoshu check finally consults the personal dictionary, and Kotoshu.detect_language identifies 176 languages through the pure-Rust lid reader.
release 7 September 2026 read the entry →
Full-feature batch 3 reaches RubyGems with 32 languages carrying modules and keyboards, plus the right-to-left tokenizer fix, on the 0.9.2 indexed-sweep base.
release 7 September 2026 read the entry →
loadLid and detectLanguage bring 176-language identification, and bucket-backed out-of-vocabulary embedding lets Teh reach The through the model path.
release 7 September 2026 read the entry →
Arabic, Indonesian, Persian, Hebrew, and eight European languages join the full-feature set: gem modules, national keyboards, and engine-verified specimens.
release 7 September 2026 read the entry →
The files input now walks the whole repository tree, and baselines, include/exclude, and SARIF suppression notes ship in the wrapper that CI actually runs.
release 7 September 2026 read the entry →
Per-word sweep invariants now live in a lazily memoized per-dictionary index, which gives 2.2x on the English average and up to 6x on short words, with byte-identical outputs.
release 7 September 2026 read the entry →
Per-word sweep invariants now live in a per-dictionary index built once at the first sweep, so heavy dictionaries gain another 1.2 to 6x, Portuguese foremost.
release 7 September 2026 read the entry →
Pure-Ruby suggestions drop from tens of seconds to under a second on full dictionaries, and the Damerau sweep ships for gem users, so Teh suggests The in first place.
release 7 September 2026 read the entry →
The suggestion sweep is 10 to 200x faster on full dictionaries, returning the same suggestions byte for byte in milliseconds instead of seconds.
release 7 September 2026 read the entry →
The Damerau edit sweep and model-generated candidates reach the browser: Teh now suggests The first, definately suggests definitely, and the playground shows every load and inference step.
release 7 September 2026 read the entry →
The two ecosystem gems republish with their actual contents after the empty 0.1.0 cuts: kotoshu-server brings semantic models over HTTP, and kotoshu-lsp brings a personal dictionary that un-flags words.
release 6 September 2026 read the entry →
Norwegian Bokmål and the no alias join the twenty language modules, and the long-reported remove_word corruption bug is fixed on RubyGems.
release 6 September 2026 read the entry →
The wave-1 program reaches RubyGems in one cut, bringing Unicode word detection for Greek and Cyrillic, directory-mode checking, baselines, inline ignores, and framework integrations for Rails, RSpec, Rake, and Jekyll.
release 6 September 2026 read the entry →
The wasm engine gains the semantic path with loadModel and rerank over the int8 tiers, and CORS-open mirrors put all 55 languages within reach of a browser tab.
release 6 September 2026 read the entry →
The registry adds Norwegian Bokmål, with nb converted from fastText’s cc.no while nn keeps cc.nn, for a total of 55 languages and 165 tiered models behind the same eval gates.
