We'll try to make this a monthly blog post in which you'll find out about new features, bug fixes, and a showcase of Svelte projects from around the community. + +## New features +1. `use:obj.method` allows functions defined within objects to be used within actions ([Example](https://svelte.dev/repl/c305722adb4a4545b27b198ea8ff9bde?version=3.27.0), **3.26.0**, warning removed in **3.27.0**) +2. `_` is now supported as a "numerical separator", similar to a `.` or `,` ([Example](https://svelte.dev/repl/844c39e91d1248649fe54af839fab570?version=3.26.0), **3.26.0**) +3. `import.meta` now works in template expressions ([Example](https://svelte.dev/repl/9630de41957a4c80a4fce264360a6bc7?version=3.26.0), **3.26.0**) +4. CSS Selectors with `~` and `+` combinators are now supported ([Example](https://svelte.dev/repl/91ad9257d2d1430185a504a18cc60172?version=3.29.0), **3.27.0**, with a compiler fix in **3.29.0**) +5. The `{#key}` block is now available to key arbitrary content on an expression. Whever the expression changes, the contents inside the `{#key}` block will be destroyed and recreated. For an in-depth explanation and to find out how it's implemented, check out the [new blog post](https://lihautan.com/contributing-to-svelte-implement-key-block/) of Svelte Team member Tan Li Hau. ([More info](https://github.com/sveltejs/svelte/issues/1469), **3.29.0**) +6. Slots can now be forwarded through child components! This used to only be possible by adding extra wrapper `
` tags and will no longer format languages which are not supported by Prettier, like SASS, Pug or Stylus. + + +## Coming up +- [Svelte Summit](https://sveltesummit.com/), Svelte's second global online conference, is taking place on October 18!
