Svelte 5 bundle size news?

[frederikhors]

I've been impressed by the speed and performance of Svelte 5 from various posts I've read.

However, I'm concerned about its bundle size. Svelte 4's bundle size tends to grow significantly with additional components.

Can we expect improvements in this regard with Svelte 5? Are there any relevant posts discussing this?

We're about to embark on a project with numerous components, and while some team members advocate for Solid, I'm in favor of Svelte. Bundle size is a critical factor for us.

Thanks for your dedication and hard work.

The team mentioned it a few times quite a long ago: the minimal bundle size is bigger, but the further increase is smaller than 4.
E.g. in https://www.reddit.com/r/sveltejs/comments/18jdxht/i_have_migrated_147_components_to_svelte_5_and/ the author got the following result of migrating 147 components to Svelte 5:

The demo build file (JS) was with v4: 382kb - and with v5: 171kb (55% smaller)!
