So I like and use Spectra (aka “ultimate addons for gutenberg”) on some of my WordPress sites.
If you use Spectra as well, you might want to be know that Spectra 2.12 has a significant performance regression, sucking in almost all of wp-includes/js/dist.
Here’s hoping this was not intentional and that it’ll get fixed soon 🙂

Update Feb. 15th: the regression is due to the new AI features, as a workaround go to Spectra -> AI features -> Manage AI features and disable “AI Assitant” (and “AI Copilot” if you don’t need/ want that either).
