PR 15082, from Rebecca Richards, fixes a namespace bug where dynamic prop patching during hydration didn't pass SVG or MathML context — so attributes like viewBox got treated as plain HTML properties and threw warnings. PR 15092 from edison1105 stops lazy hydration from running on detached…
Server rendering got similar attention. PR 12601 routes errors from optimized component renders through Vue's standard error handling instead of letting them slip past. PR 15071 from cernymatej fixes a memory leak where a thrown error during slot rendering left rendering blocks improperly closed. And PR 15045 closes…
Second theme: reversals. Edison1105 shipped two straight reverts today — PR 15094 and PR 15095 — walking back changes from PRs 14985 and 14986 that paused reactive tracking inside function template refs. Evan's original guidance said that tracking is intentional: refs can run on every render, and reactive state can…
