 _New/Updated Syntax_
 
-- `<svelte:boundary>` is a new special element that can capture errors that occur from within its subtree during client rendering (**5.3.0**, [Docs](https://svelte.dev/docs/svelte/svelte-boundary), [#14211](https://github.com/sveltejs/svelte/pull/14211))

Any time the function re-runs as part of an effect or a derived, information will be printed to the console about which pieces of reactive state caused the effect to fire (**5.14.0**, [Docs](https://svelte.dev/docs/svelte/inspect#inspect.trace()), [#14290](https://github.com/sveltejs/svelte/pull/14290))
