Inertia.js v3.7.0 adds a cancelOnUnmount attribute and a cancel method to the Form component so in-flight submissions can be aborted when a form unmounts or via a button click. usePoll now exposes a reactive polling value across Vue, React, and Svelte. Once props no longer lose their value during instant visits, and navigation no longer cancels background async visits aimed at other pages. Three fixes address a React back_forward stale-props bug, prop identity issues in replaceProp/appendToProp/prependToProp, and a Form unmount crash in React.
