Happy February, everyone! Over the last month or so, we've seen Svelte and SvelteKit [develop at rapid speed](accelerating-sveltes-development), 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.
