Highlight Featured this release ## PR reviews prove bug fixes with a before/after reproduction The review agent reproduces the original behavior on your base environment before showing it resolved on the preview. For bug-fix pull requests, the [review agent](https://qa.tech/product/pr-testing) derives the failure from the fix itself, drives your app into the state that triggers it, and runs the same check against both your base environment and the [PR preview](https://docs.qa.tech/core-concepts/applications-and-environments). The review comment now opens with a Reproduction section showing the before/after result with screenshots, so a passing review means the behavior was actually confirmed and fixed rather than just a happy path run.

Update 02 of 08 ## Jump straight from your PR list to the review conversation A new icon on the pull request list takes you directly to the review conversation. Rows with an associated review conversation now show a link icon in the pull request table. Click it to go straight to the conversation instead of opening the PR, scrolling to reviews and clicking through. More on [pull request testing](https://qa.tech/product/pr-testing).

Update 03 of 08 ## Knowledge rules open in a shareable side sheet Rules under Settings → Knowledge are now a sortable table, and each one opens in a linkable side panel. Click any rule to open it in a side sheet with its own URL, so you can share a direct link to a specific rule instead of describing where to find it. Editing happens inline in the sheet, and rules with JSON content are pretty-printed in a monospace block instead of rendering as a wall of wrapped text. See [knowledge](https://docs.qa.tech/core-concepts/knowledge). [\# Direct link](#2026-08-26-knowledge-rules-side-sheet) 4. Update 04 of 08 ## PR reviews now test your dependency updates Package and lockfile bumps are now tested against the flows they actually touch. When a pull request is primarily a dependency update, the [review agent](https://qa.tech/product/pr-testing) identifies which changed packages affect runtime behavior and tests the flows that exercise them, falling back to a core smoke pass when no specific surface is affected. Purely build and dev-tooling bumps still get a clear "unable to review", so a real behavior change dressed up as a routine bump gets covered instead of waved through.

Update 05 of 08 ## Preview downloaded files without leaving the run The Download Viewer has a dedicated Preview button, so you can check a file an agent downloaded during a test. Every completed download in the Download Viewer now shows a named "Preview" button alongside the file, opening its contents inline. Fast downloads open the preview immediately; slower ones show a clear in-progress state until the file is ready. See [file downloads](https://docs.qa.tech/test-features/file-downloads). [\# Direct link](#2026-08-26-preview-downloaded-files-in-run) 6. Update 06 of 08 ## Steer a running chat with ⌘Enter Press ⌘Enter (Ctrl+Enter on Windows and Linux) to have a message picked up immediately instead of waiting in the send queue. Messages sent while the [chat agent](https://docs.qa.tech/core-concepts/ai-chat-assistant) is mid-turn used to wait for the whole chain to finish. Regular Enter still queues that way. ⌘Enter marks a message for immediate delivery: the running agent picks it up at its next step and works it into the response. A "⌘ + Enter to send now" hint appears next to the send button while a turn is in progress, and force-sent messages show as "Sending now" in the queue. [\# Direct link](#2026-08-26-steer-a-running-chat-with-cmd-enter) 7. Update 07 of 08 ## Faster todo triage: priority sorting and clearer rejection reasons Todos default to urgent-first order, and rejecting one takes a picked reason instead of a blank text box. The Todos list now sorts by priority automatically, with newest-first as the tiebreaker, so the most urgent items surface without any manual sorting. Rejecting a todo starts with a reason picker – including an "Other" option for anything custom – instead of requiring free-form text every time, which makes rejected items easier to scan and compare later.

Update 08 of 08 ## Tracer timeline shows the step numbers your assessment cites Assessment findings reference "Step 5" – the tracer timeline now shows that same number, so you can find it at a glance. Each row in the test-run tracer timeline is now labeled with the step number the assessment report uses, and clicking a "Step N" badge in the report jumps to the matching row. Collapsed step cards show the range they cover, for example "#4–6", until you expand them. [\# Direct link](#2026-08-26-tracer-timeline-step-numbers) ## Your team moves fast.
