- Previously, any each block parents where used as keys for the sub group. That's wrong, it should only be using each blocks whos declarations contribute to the `bind:group` expression. Fixes#10345
- Only the left-most identifier of the expression was used to determine the binding group. This is wrong, all identifiers within the expression need to be taken into account. Fixes#9947
* fix: don't reuse proxies when state symbol refers to stale value
When somebody copies over the state symbol property onto a new object (you can retrieve the symbol by using `Reflect.ownKeys(...)`), it was wrongfully assumed that it always relates to the current value. This PR adds an additional check that this is actually the case.
This also adds a dev time warning when an object is frozen but contains a state property, which hints at a bug in user land.

We're now on Svelte v5.0.0-next.42 which made one test match the 42 of the next version instead of the number in the code, resulting in that test suddenly failing. This fixes the regex to replace that number with x's instead
* fix: improve unstate handling of non enumerable properties
* Update packages/svelte/src/internal/client/proxy.js

The generated types were invalid TypeScript ("cannot use unique symbol at this position"). Use utility types to ensure the types are not unpacked during type generation.

If you had `on:` directives listening to the same name (through multiple on:click on the same element or indirectly through multiple `<svelte:window>` elements with event listeners of the same name) there was a bug of delegation firing too often. This PR fixes that by tweaking the "should I continue with the given path index" logic.
