## @scalar/snippetz 0.10

### New APIs and options

- HTTP clients can set the multipart boundary. (0.10.6) — [release notes](https://github.com/scalar/scalar/blob/efb009aff3e0dd32bce9399bf71fa99bb8818ac9/packages/snippetz/CHANGELOG.md#0106)
- The exported type accepts custom method strings while retaining known-method editor completion; consumers must handle unknown methods because the type is not exhaustive over fixed HTTP methods.

## @scalar/snippetz 0.9

### Breaking changes

- A plugin’s client type is now constrained by its target, so mismatched clients and display titles where lowercase client IDs are expected produce TypeScript errors.
