I really really like Astro, but I'm either getting old or it's something else.
I just recently updated my website to Astro 6 and now... there's Astro 7. Maybe by the time I update, Astro 8 will be a few weeks in the future.
We unfortunately released Astro 6 only a few weeks before Vite 8 / Rolldown came out, which is why we did Astro 7 so soon. But there are very few breaking changes compared to Astro 6. That being said, some of these performance improvements (the Sätteri processor) are available in Astro 6 too.
(As an outsider, ) I suspect it's because the Rust rewrite was big enough to bump the main version number.
Cloudflare bought Astro recently, and as it states in docs it previously had cache plugins for 2 companies but not Cloudflare so that may have been a motivation along with the Vite update mentioned
