Update 01 of 02 ## Sonnet 5.5 is the default for pull request reviews Claude Sonnet 5.5 joins the chat model picker and powers pull request reviews on Auto. Pick Sonnet 5.5 from the chat composer alongside Opus 5.5 and Sonnet 5. Chat on Auto stays on Opus 5.5, while pull request reviews now use Sonnet 5.5 by default. The models settings page reflects the change. More on this: [PR testing](https://qa.tech/product/pr-testing) and [product overview](https://qa.tech/product).

Update 02 of 02 ## Visual changes only when there's something to show PR reviews post up to three before/after crops per page and skip the Visual changes section when there are no pictures. When a page has several distinct visual changes, the review now shows up to three before/after crops. Surfaces already covered by the reproduction screenshots aren't repeated, and the "Visual changes" heading is left out when there is nothing to show.
