Vue

The CHANGELOG.md in vuejs/core is the ongoing known-issues surface for Vue 3 and its successors. Breaking changes appear inline under a consistent header per version entry, alongside deprecation notices and reactive-system edge cases; the file is the right first stop when a minor or patch upgrade produces unexpected behaviour.

The Vue 2 to Vue 3 migration sits in a dedicated guide at v3-migration.vuejs.org rather than in the changelog, which means the two surfaces operate on different cadences. The rewritten v-model semantics, the removal of filters, and the shift to the Composition API are each documented in that guide; a team upgrading from Vue 2 that reads only the changelog will miss the most structurally significant breakage before it reaches runtime.
