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** — Fixed concurrent cold-start requests from intermittently losing authentication or transaction context due to an async storage initialization race
- **fixed** — Fixed automatic organization assignment via email domain to require both a verified provider domain and a verified stored user email, preventing social sign-in from joining an organization whose SSO provider merely claims that domain
- **fixed** — Fixed domain verification to snapshot the provider's domains at request start, returning 409 with SSO_PROVIDER_CHANGED if the provider changes during DNS resolution so callers can reload and retry
