Version Packages

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.

 # @vintl/nuxt
 
+## 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
+
+### Patch Changes
+
+- 6479891: VIntl updated to the latest version
+
+  Latest version of VIntl fixes missing type declarations for global properties, like `$t`, `$fmt` and `$i18n`.
+
+  We might add automatic handling for disabling of `controllerOpts.globalMixin` in the future releases. You can follow the status update in [#74](https://github.com/vintl-dev/nuxt/issues/74).
+
+  For now, if you disable global mixin, use the below augmentation to disable these unusable properties:
+
+  ```ts
+  declare global {
+    namespace VueIntlController {
+      interface Options {
+        globalMixin: false
+      }
+    }
+  }
+  ```
+
+## 1.7.0
+
+### Minor Changes
+
+- a9fdc59: Add support for parsing the messages in the error handlers
+
+  With [update to `@vintl/unplugin`](https://github.com/vintl-dev/unplugin/releases/tag/v1.5.0), it's now possible to use `parseMessage` from the error handler's context to parse custom messages or re-parse the current message with any modified options.
+
+## 1.6.0
+
+### Minor Changes
+
+- 81c23b0: Support for parsing error handling
+
+  `@vintl/nuxt` can now handle errors when parsing message files containing broken messages in a configurable manner.
+
+  You can configure how errors are handled using `onParseError` module option, which can either be a name of the built-in strategy, or a function that takes in context and optionally provides fallback message AST.
+
+  Check out documentation for more information.
+
+### Patch Changes
+
+- 2b5a59b: Unpin FormatJS dependencies
+
+  We proveviously had `@formatjs/intl` pinned because of the broken ESM migration, however this has been fixed for quite some time already, so the pinned version has been to changed to a range, which ensures that `@formatjs/intl` can be updated with latest bug fixes and improvements until the next major version.
+
+## 1.5.0
+
+### Minor Changes
+
+- 979f2bd: Add more SEO options
+
+  Two options have been added to the SEO configuration:
+
+  - `defaultLocaleHasParameter` allows to disable the host language parameter for the default locale.
+
+    This is not recommended and not correct, because lack of the host language parameter instructs VIntl to use user's language (either the one they've used before or browser's one). However, it may be useful in some cases.
+
+  - `xDefaultHreflang` allows to disable the `x-default` hreflang in case it's not useful to have (e.g. you disable the automatic language detection), although this is quite rare.
+
+## 1.4.0
+
+### Minor Changes
+
+- e1c501c: Improve alternate links generation
+
+  Generation of `alternate` `hreflang` links has been improved to properly use absolute URLs.
+
+  Since there's no good way to know the URL of the site, there's now also `seo.baseURL` option which allows to set site's proper domain.
+
+  `hostLanguageParam` option has been deperecated in favour of `seo.hostLanguageParameter`, which functions almost the same way, except it does not accept `null`. If you want to disable generation of such tags or handle them yourself, you can set `seo.enabled` to `false`.
+
+  See [Configuration](https://vintl-nuxt.netlify.app/introduction/configuration#seooptions) documentation page for more details.
+
+## 1.3.0
+
+### Minor Changes
+
+- 951f363: Add graceful fallback for unknown locales in storage
+
+### Patch Changes
+
+- ae71089: Use automatic locale if none returned by the storage
+
+  Fixed a bug where automatic locale would not be restored from the storage properly on the next page reload, despite it being saved properly.
+
+## 1.2.3
+
+### Patch Changes
+
+- db449d4: Fix missing options in the newer Nuxt versions
+
+## 1.2.2
+
+### Patch Changes
+
+- 2590b2f: Downgrade and pin versions of FormatJS packages
+
+  Newest versions of FormatJS packages contain exports map that result in illegal ESM as CJS imports. This downgrades them
+
+  For more details see the issue at https://github.com/formatjs/formatjs/issues/4126.
+
+## 1.2.1
+
+### Patch Changes
+
+- f62ae92: Adapt to new export conditions of the parser
+
+  `@formatjs/icu-messageformat-parser` has been updated and now has export conditions, this change adapts and fixes the error caused by the previous direct import of the file for `no-parser` alias.
+
+- 47f1739: Fix consola not being actually listed as a dependency or used
+
+## 1.2.0
+
+### Minor Changes
+
+- 3d41dd1: Update VIntl to 4.2.0
+
+  Previously VIntl was depending on Vue directly, which caused issues, and wasn't correct, as Vue is not its implementation detail. 4.2.0 made Vue a peer dependency, fixing this issue. It also brought updates to other dependencies like `@formatjs/intl`.
+
+### Patch Changes
+
+- 9756d4a: Upgrade `import-meta-resolve` to v3
+
 ## 1.1.4
