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.

- **fixed** — Fixed registerFileProtocol and registerHttpProtocol returning readable responses to cross-origin no-cors fetches; they now return opaque responses like protocol.handle
- **fixed** — Fixed a WebContentsView staying blank after its window is shown when setBackgroundThrottling(false) was called while the window was hidden
- **fixed** — Fixed a crash when resolving a path inside a malformed ASAR archive that contains cyclic link entries
- **fixed** — Fixed downloading files that live inside an asar archive, including saving a packed PDF from the built-in PDF viewer
- **fixed** — Fixed windows opened by a sandboxed top-level frame not inheriting the opener's sandbox restrictions
- **changed** — <webview> and window.open now inherit nodeIntegrationInWorker from the embedder, consistent with the other Node and sandbox preferences
