Version Packages

Composite files are not allowed to use `noEmit`, however, we need to
prevent TypeScript from compiling the files, as this would override JS
files (in our case, eslint.config.mjs). Seems this can be avoided by
emitting declarations only. It's not like were actually going to use
TSC to build the project...

 # @vintl/nuxt
 
+## 1.9.1
+
+### Patch Changes
+
+- a26c360: Switch to the official Nuxt module template
+
+  This should resolve any issues with our Nuxt-specific imports, e.g., breakage of the Nuxt injections (added through `provide`s in plugins) due to the invalid `Plugin` type specified by our package (sorry for that!).
+
+## 1.9.0
+
+### Minor Changes
+
+- efdcdb9: Replaced Zod validation with a much simpler normalization and assertion 🚀
+
+  This brings a huge TypeScript performance boost for both maintainers and users of the module.
+
+  Developers using the module will also be happy to discover that each option is now documented (they always were, but documentation was erased from Zod inferred types by TypeScript) and each type used in options can be exported if you need to programatically extend the options.
+
+  Better yet? Common mistakes are still checked and pretty printed!
+
+  See the full explanation for decision to switch from Zod in the commit message.
+
+  🐞 If you stumble upon a bug caused by this switch, please [report them on issue tracker](https://github.com/vintl-dev/nuxt/issues).
+
+### Patch Changes
+
+- 9e42c63: Fixed a typo in message about message that cannot be parsed
+
+## 1.8.1
+
+### Patch Changes
+
+- 114d04a: Switched to a slightly more compatible `#app` augmentation
+
+## 1.8.0
+
+### Minor Changes
+
+- 9d939c1: Switched to using module ID markers
+
+  Previously VIntl for Nuxt kept track of files that were used as locale messages and matched module IDs based on them. This, however, was very unreliable in certain environments.
+
+  With this change VIntl for Nuxt now uses ‘markers’, URL parameters added to the end of imported module IDs. This allows it to very quickly test whether a specific module is imported through a message file and should be processed by the VIntl unplugin.
+
 ## 1.7.1
