The Vue core team has published v3.6.0-rc.6, the latest release candidate in the 3.6 minor branch. This pre-release version focuses on stabilising the new features and addressing regressions found during the RC phase, as detailed in the branch-specific CHANGELOG.md (the main CHANGELOG.md is reserved for stable releases).
Key highlights in this RC include:
- Compatibility and bug fixes for the compiler-sfc package, ensuring that single-file component transformations behave correctly in edge cases involving
defineModelanduseTemplateRef. - Reactivity system refinements: Improved handling of
watchandcomputedwhen dealing with symbol keys and reactive arrays, reducing unnecessary re-renders. - Server-side rendering (SSR) adjustments: Fixes for hydration mismatches when using
v-memoandv-fortogether, which previously could cause incomplete DOM patches. - TypeScript type updates: Expanded typings for lifecycle hooks and the
onWatcherCleanupAPI (introduced in 3.5) to better reflect permissible usage patterns and edge conditions. - Performance micro-optimisations in the runtime-core scheduler, particularly for flushing pre-flush queue callbacks.
The release also outlines that, for pre-releases, developers should always refer to the CHANGELOG.md in the minor branch (e.g., v3.6.0-rc.6), as the stable CHANGELOG.md is only updated for final releases. This distinction is crucial for those tracking the 3.6 development cycle and for ensuring they are testing the latest fixes.
For developers currently experimenting with 3.6 features, upgrading to this RC is recommended to catch any lingering issues before the final stable release. The RC phase indicates that the feature set is essentially frozen, and only critical bugs are being addressed. By validating your application against v3.6.0-rc.6, you can minimise upgrade friction when Vue 3.6.0 stable ships.
