Breaking Changes

●Issue #1

On the server, the promise returned from `refresh` now represents adding the refresh to the map, rather than the time it takes to run the remote function. Code relying on the previous behavior of the `refresh` promise must be updated.

Migration Steps

  1. 1
    Review usage of the promise returned by `refresh` on the server side to align with the new behavior (it now represents adding the refresh to the map).

Release Summary

This release introduces support for `query.batch` and the experimental `query.live` function, alongside a breaking change in the behavior of the server-side `refresh` promise. Several bugs related to form handling and updates have also been resolved.
