What happened
WooCommerce 11.1 skips block registration on requests that cannot render blocks, according to the WooCommerce Developer Blog.
The publisher says the change makes Store API and REST requests 40% faster.
Extensions that render Woo blocks on affected requests can opt back in using a new block registration filter.
The available evidence is a single official-source title and summary; no source body or quotation was retained.

Why it matters
For stores and extensions that do not render blocks during Store API or REST requests, less block-registration work may improve request speed.
For an extension that depends on block registration during those requests, the default change could alter expected behavior unless the extension opts back in.
The reported 40% improvement is a publisher claim, so merchants should validate the effect in their own stack rather than assume the same gain.
