Johnson from the Vue core team has developed and released a new reactivity system called 'alien-signals' in version 1.0. This system is reportedly 4 times faster than Vue 3.4 and 1.8 times faster than Vue 3.5. Evan You confirmed that this new system will be included in Vue 3.6.

3X Faster Reactivity Arrives in Vue 3.6
