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.
SavvyCal lets Claude or ChatGPT book and move meetings through an MCP server on every plan.
SavvyCal ships about once a month, and its latest release is the largest in a year: an MCP server on every plan that lets AI assistants find times, book or move meetings, block time and run polls. Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.

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.

Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.
For most of the year SavvyCal has added control for hosts and assistants who schedule for others. The MCP server extends that to software assistants: the same booking and rescheduling actions now work from a chat. That puts SavvyCal's scheduling logic inside other tools instead of only on its booking pages.
Expect follow-ups that widen what the MCP server can do, such as more scheduling actions. The single release gives little else to predict from.
