Knock adds single-step test runs and retries for failed workflow runs.
Knock is a notification infrastructure platform that spent September and October wiring itself into AI assistants (Claude, ChatGPT/Codex, Cursor) and Stripe Projects. Its latest two releases turn to the workflow debugger: a failed run can now be retried from where it stopped, and a single channel step can be tested in sandbox without running the whole workflow.
Payload's v4 beta.9 keeps every past image crop and raises the Node floor again.
Payload has tagged nine v4 betas since October 10. Beta.9 reads saved crops and focal points from the new _transforms store, serves historical upload variants when a version is restored, adds labels and device details to sessions, and exports standalone CSS tokens from the UI package. It also bumps the minimum Node version to 24.22.3, the second Node floor raise in the cycle.

With distribution through AI tools in place, Knock is now improving the day-to-day build-and-debug loop for workflows, following the September analytics tab. The pattern points to more operational tooling around runs, not new channels.
Expect further debugger and test-runner features, such as bulk retries or replays with edited data, given two debugging releases in three days.

It also bumps the minimum Node version to 24.22.3, the second Node floor raise in the cycle.
Three betas in a row have reworked file uploads around one stored original plus replayable transforms, and two have tightened sign-in and sessions. The v4 cycle is now finishing those two systems rather than adding new surfaces, which is the usual shape of a beta nearing a release candidate.
Expect more betas that close out the transforms and session work, with a release candidate once the fix lists shrink; the entries do not show a date.
