# Apple News API Release Notes Learn about new features that require iOS 26, iPadOS 26, and macOS 26. ## Discussion These features were added in the latest Apple News API release: - The [`Create an Article`](/documentation/AppleNewsAPI/POST-channels-_channelId_-articles) endpoint throws a 400 error if you attempt to publish an article bundle exceeding 450 MB. - The [`Update an Article`](/documentation/AppleNewsAPI/POST-articles-_articleId_) endpoint throws a 400 error if you attempt to update an article bundle exceeding 450 MB. These features were added in a previous Apple News API release: - The [`Create an Article`](/documentation/AppleNewsAPI/POST-channels-_channelId_-articles) endpoint throws a 400 error if you attempt to publish an article with a publication date before 1970, and a warning if the publication date is before 2015. - The [`Update an Article`](/documentation/AppleNewsAPI/POST-articles-_articleId_) endpoint throws a 400 error if you attempt to update an article with a publication date before 1970, and a warning if the publication date is before 2015. This field is no longer supported in Apple News API: - `accessoryText` is deprecated in [`Create Article Metadata Fields`](/documentation/AppleNewsAPI/Create-Article-Metadata-Fields) and [`Update Article Metadata Fields`](/documentation/AppleNewsAPI/Update-Article-Metadata-Fields). Use the `authors` property in the Apple News Format [`Metadata`](/documentation/AppleNewsFormat/Metadata) object instead. --- Copyright © 2026 Apple Inc.
