Version 12.0.0
The primary breaking change is to the format of the imported/exported biblio, in #425. Using this version with the ecma262 biblio will require major version 2 of @tc39/ecma262-biblio.
A secondary breaking change in #426 is that the "user code" annotation is only rendered when using the --mark-effects cli flag or putting markEffects: true in the programmatic options or metadata.
