Breaking Changes

@azure-tools/typespec-autorest: Config interpolation

output-file now use config path interpolation. Existing value must be change to include the values to interpolate. e.g. custom.json -> {azure-resource-provider-folder}/{service-name}/{version-status}/{version}/custom.json

@azure-tools/typespec-autorest: Remove deprecated decorator

Removed deprecated @collectionFormat decorator. Use @header({format: }) or @query({format:}) instead.

Example:

// Before
op list(@collectionFormat("multi") @query select: string[]): Pet[];

// Now
op list(
  @query(#{ explode: true })
  select: string[],
): Pet[];
