Happy February, everyone! Over the last month or so, we've seen Svelte and SvelteKit develop at rapid speed, new community rules across the [Reddit](https://www.reddit.com/r/sveltejs/comments/s9n8ou/new_rules/), [GitHub](https://github.com/sveltejs/community/blob/main/CODE_OF_CONDUCT.md) and [Discord](https://discord.com/channels/457912077277855764/831611707667382303/935264550436102315), and quite a few amazing apps, tutorials and libraries.

Let's take a look...

## Highlights from the Svelte changelog
- **3.45.0** brought a [new a11y warning `a11y-no-redundant-roles`](https://svelte.dev/docs#accessibility-warnings-a11y-no-redundant-roles), destructring and caching fixes
- **3.46.0** added the much requested [`{@const}` tag](https://svelte.dev/docs#template-syntax-const) and [`style:` directive](https://svelte.dev/docs#template-syntax-element-directives-style-property)
- Check out **3.46.1 - 3.46.3** for fixes to the `{@const}` tag and `style:` directive, along with a number of fixes to animations

## What's new in SvelteKit
- `inlineStyleThreshold` allows you to specify where inline stylesheets are inserted into the page ([#2620](https://github.com/sveltejs/kit/pull/2620))
- `beforeNavigate`/`afterNavigate` lifecycle functions lets you add functionality before or after a page navigation ([#3293](https://github.com/sveltejs/kit/pull/3293))
- Content Security Policy (CSP) is now supported for increased security when using inline javascript or stylesheets ([#3499](https://github.com/sveltejs/kit/pull/3499))
- `kit.routes` config allows you to customise public/private modules during build ([#3576](https://github.com/sveltejs/kit/pull/3576))
- `prerender.subfolders` config lets you prerender index.html files as their subfolder's name ([#2632](https://github.com/sveltejs/kit/pull/2632))

## Community Showcase

**A quick note before diving into the Showcase:** The 2021 [State of JS](https://stateofjs.com/) survey is now live (yes, in 2022). A lot of newcomers to Svelte saw it for the first time in the State of JS survey and, every year, Svelte gets more and more attention through it. If you've got a few minutes, please share your honest opinion about Svelte in the survey. It means a lot!
