infochangedSlack calls it: Release

Release: Java Slack SDK v1.49.0

Announced: 2026-06-03
APIs: java-slack-sdk
Endpoints: assistant.threads.setStatus chat.startStream files.completeUploadExternal
Severity: info, set by reef/slack-rule-v1
Source: https://docs.slack.dev/changelog/2026/06/03/java-slack-sdk

We've added authorship arguments (icon_emoji, icon_url, and username) to the assistant.threads.setStatus and chat.startStream API methods.
We've added highlight_type support to the files.completeUploadExternal and filesUploadV2 API methods. The highlight_type parameter allows specifying the file type hint for uploads (e.g., png, jpg, and gif file types), enabling optimistic rendering before the async upload processing job completes.

The text above is Slack's. reef added the severity, the dates it could read from the text, and the endpoints and scopes named in code.
