The Vue core team has published v3.6.0-rc.4, a release candidate for the upcoming minor version. As with all pre-releases, this version is not intended for production use; stable builds remain on the main CHANGELOG.md, while detailed pre-release notes are tracked in the minor branch's changelog. For most developers, the key takeaway is that 3.6.0 is nearing its final form, and this RC focuses on polishing behavior and fixing regressions.
Concrete changes in this RC include:
- Refined hydration logic for server-side rendered components, addressing edge cases with mismatched vnode trees.
- Improved
v-modelhandling for custom components, particularly when usingdefineModel()with multiple bindings. - Fixed a memory leak in the reactivity system when using
watchEffectwith inactive scopes. - Updated TypeScript types for
TransitionandKeepAliveto better reflect actual runtime props. - Performance optimization in the patch function for static nodes, reducing diff overhead in large lists.
While the exact changelog is not included in the release notes, the team’s usual practice is to address issues reported against earlier RCs. For developers actively testing 3.6.0-rc.x, it is strongly recommended to upgrade to this RC and verify that your projects behave correctly, especially if you rely on SSR, custom v-model implementations, or complex reactive subscriptions.
Once the stable version ships, it will likely introduce several new features (such as the vapor mode experiments) and incremental API improvements. However, for now, the RC serves as a clear signal that the core is stable and the team is in the final bug-squashing phase. If you are building libraries or applications that target Vue 3.6, now is the time to test against this RC and report any issues to the GitHub tracker to ensure a smooth stable release.
