What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **fixed** — Fix readFile writing the API error JSON into the destination when the file response is not an octet-stream by rejecting any non-application/octet-stream response instead of piping it verbatim to the caller's stream

###### Patch Changes

-   Fix `readFile` writing the API error JSON into the destination when the file response is not an octet-stream. The SDK now rejects any non-`application/octet-stream` response (including 2xx with a JSON error body) instead of piping it verbatim to the caller's stream. ([#202](https://github.com/vercel/sandbox/pull/202))
