### \[0.1] - 2026-08-14

A substantial reliability and speed release, with finer control over what you extract and
clearer answers when a video can't be transcribed.

#### Added

- **Transcript cleaning levels** — choose `none` for the text exactly as published, `mild` to
  remove filler sounds, or `aggressive` to also strip conversational fluff.
- **Optional timestamps** — turn the per-segment timestamp list off for a lighter result when
  you only need the full transcript text.
- **Transcript word count and covered duration** on every result, returned whether or not you
  keep the timestamp list.
- **Transcript availability reason** — when a video has no transcript you now get an
  explanation (captions disabled, video unavailable, and so on) instead of an empty field.
- **Resume support** — an interrupted or restarted run skips videos it already delivered, so
  you are never billed twice for the same video.
- **Concurrency and batch-size settings** — tune how many videos are processed in parallel and
  how often results are delivered.
- **A comments-focused data view**, alongside the full, transcript and channel views.
- **Documented output** — every field in the results is now described with its type and an
  example, so the output is self-explanatory in the Console and over the API.
- **Result provenance** — each record carries its source and originating URL, so rows stay
  traceable after you merge datasets.

#### Changed

- **Faster runs**, particularly when a video or a network hop is slow: requests that stall are
  now abandoned quickly instead of holding up the rest of the batch, and independent work runs
  in parallel rather than one step after another.
- **Videos without a transcript are delivered free.** They previously produced nothing at all;
  you now receive the full metadata for them at no charge, with a field stating why they were
  not billed.
- **Results arrive in batches as they complete**, rather than only at the end of a run.
- Runs that reach a spending limit now deliver everything already accounted for before
  stopping.
- Runs that produce no results explain why — every URL invalid, duplicated, or already
  processed — instead of finishing with an empty dataset.
- Paid-plan runs now reliably receive the faster processing path.
- The Standby API description now matches the service exactly: request options, response
  fields and streamed events.

#### Fixed

- Transcript cleaning and timestamp settings had no effect; both now work as described.
- Word count and duration were advertised in the output but never populated.
- Requesting full metadata through the Standby API could return only the transcript.
- A comment-extraction failure no longer discards the video's transcript and metadata — the
  video is still delivered, with the comment error recorded on the record.
- Several settings the Actor accepted were missing from the input form and could only be sent
  over the API.
- Long or repeatedly failing videos could stall a run far longer than intended.
