## @glint/tsserver-plugin 2

### Breaking changes

- The v2 CLI binary is a thin wrapper around tsc for type-checking .ts, .gts, and .gjs files; it may require additional tsc-style arguments compared with v1 glint. (2.0.0) — [upgrade guide](https://typed-ember.gitbook.io/glint/v2-upgrade)
- Add this ambient import to provide Glint v2 types. (2.0.0) — [upgrade guide](https://typed-ember.gitbook.io/glint/v2-upgrade)
- Glint v2 no longer supports Handlebars templates, including .hbs files backed by separate .ts or .js component classes. (2.0.0) — [upgrade guide](https://typed-ember.gitbook.io/glint/v2-upgrade)

### Tooling

- Glint v2 is provided as a sibling extension rather than an upgrade to the v1 extension, enabling a hybrid upgrade path; only one version may be enabled in a workspace. (2.0.0) — [upgrade guide](https://typed-ember.gitbook.io/glint/v2-upgrade)
