Model or tool update? Pair official notes with a small test

Use this thread to discuss a model or tool update with enough context for others to evaluate its relevance. There is no specific release claim in this opening post; add the update you want to discuss.

A useful contribution includes:

• The official announcement or release-note link and publication date.
• The exact product and version or model identifier.
• The change described by the maintainer.
• The workflow you think could be affected.
• A small test you ran or propose to run.
• Observed results, limitations, and questions still open.

If you compare before and after behavior, record both environments and use the same inputs. Label reports from other people as second-hand and link the original source.

What would you need to verify before adopting the update in your own project?
