Vue's experimental Vapor compiler just broke event handling to make it faster: event delegation is now opt-in, not automatic.

Vue-jsx-vapor v3.2.21 landed with a compiler overhaul that replaces the logicalIndex system with block placeholders [1], a fundamental shift in how the compiler tracks component structure. The same release flips event delegation from on-by-default to opt-in [1], giving you control over performance versus convenience. This tracks closely with upstream changes copied from vue/core [2] that fix event modifier preservation and quoted attribute spacing. The patch also resolves slot fallback behavior across multiple roots [3], addressing a corner case that would have bitten production code. In 8 commits across the experiment, zhiyuanzmj has been steadily pulling fixes from the mainline, suggesting Vapor is moving closer to stability.
