Additionally, Nuxt provided some template utilities (`serialize`, `importName`, `importSources`) for code generation within these templates. These utilities are now being removed. - -### Reasons for Change - -In Nuxt v3, we moved to a 'virtual' syntax with a `getContents()` function, which is much more flexible and performant. Additionally, `lodash/template` has had multiple security issues.
