 ## Unreleased
 
+* Fix placement of `{@html}` when used at the root of a slot or the root of a component ([#5012](https://github.com/sveltejs/svelte/issues/5012))
 * Fix handling of `import`ed value that is used as a store and is also mutated ([#5019](https://github.com/sveltejs/svelte/issues/5019))
 * Do not display `a11y-missing-content` warning on elements with `contenteditable` bindings ([#5020](https://github.com/sveltejs/svelte/issues/5020))
 * Fix handling of `this` in inline function expressions in the template ([#5033](https://github.com/sveltejs/svelte/issues/5033))
 * Update `<select>` with one-way `value` binding when the available `<option>`s change ([#5051](https://github.com/sveltejs/svelte/issues/5051))
+* Fix published `tweened` types so the `.set()` and `.update()` options are optional ([#5062](https://github.com/sveltejs/svelte/issues/5062))
+* Fix contextual `bind:this` inside `{#each}` block ([#5067](https://github.com/sveltejs/svelte/issues/5067))
