Releases are made with Changesets and published from GitHub Actions with an npm provenance attestation. The GitHub releases page lists the tags.

0.4.0

Minor Changes

• 48afdae: - Web Worker inference. provideTransformersWorker() and the new ngx-transformers/worker entry point (runTransformersWorker(), createWorkerPipelineFactory()) run every pipeline off the main thread with the same handles and signals; progress, streamed tokens and tensor results cross the boundary.
  • Text generation. createTextGenerator() runs a small language model (SmolLM2-135M-Instruct by default) with token streaming: an output signal, an onToken callback, chat or plain prompts.
  • Reactive inference. inferenceResource() runs a handle whenever an input signal changes, as an Angular resource with debounce and latest-wins.
  • Overall download progress. progress().overall sums every file of a model and <ngx-model-progress> drives its bar with it, instead of jumping between files.
  • Run errors. A runError signal on handles and the translator holds the error of the most recent run.
  • Every wrapper method accepts a signal (AbortSignal) run option: a run whose signal fired while the model was still loading rejects with an AbortError instead of queueing.
  • TransformersDtype gains int8, uint8, bnb4 and q4f16.

0.3.1

Patch Changes

• d29219f: Fix two PipelineHandle lifecycle races. dispose() during a model download now cancels the load: the model is released when it arrives, the handle stays idle, its progress events are ignored, and a run() that was waiting on that load rejects with a clear error instead of the model leaking and the status flipping to ready after the owning component was destroyed. Overlapping run() calls now keep the status busy until the last one finishes instead of the first one to complete flipping it back to ready. Handles and translators created with create*() are now destroyed, not merely disposed, with their component: destroy() releases the model and makes later load() / run() calls reject, so a stale callback can no longer re-download a model nobody would free. dispose() keeps its meaning and still allows a reload.

  The npm package now ships the LICENSE file and the current README (both copied from the repository root at build time; the package README for 0.3.0 still listed zero-shot classification and translation under "Roadmap").

  Add createDefaultPipelineFactory(), the lazy-importing factory behind PIPELINE_FACTORY, so apps can wrap it (logging, extra options) instead of re-implementing the import.

0.3.0

Minor Changes

• 8062311: Add createZeroShotClassifier() (classify(text, labels, { multiLabel, hypothesisTemplate }), MobileBERT MNLI by default) and createTranslator() (translate(text, { from, to }) with one lazily loaded opus-mt model per language pair, multilingual checkpoints supported through src_lang / tgt_lang, pair-to-model overrides via provideTransformers({ translationModels })). PipelineHandle gains a protected runWith() for tasks that take positional arguments beyond the input.

Patch Changes

• 19e318f: Add hasWebGpu() and detectDevice(), a cached WebGPU probe that also requests an adapter and resolves to the WASM answer on the server, plus an autoDevice option for provideTransformers() that picks 'webgpu' when available for every handle without an explicit device.

0.2.1

Patch Changes

• 5f543b9: Releases are now automated with Changesets and published from GitHub Actions with provenance.
