Bump dependencies

#7674 Upgrade dependencies

Bug Fixes

1.1.0

No changes, version bump only.

1.0.1

Bug Fixes

#7259 Fix diagnostic for PatchOptions.implicitOptionality, which refers a non-existing property and the incorrect value. To keep the old behavior, you will need to use @patch(#{ implicitOptionality: true }) instead.

1.0.0

Breaking Changes

#7230 Changed @patch so that it does not apply the "implicit optionality" transform by default anymore.
```
@patch op update(@body pet: Pet): void;
```
To use JSON Merge-Patch to update resources, replace the body property with an instance of MergePatchUpdate as follows:
```
@patch op update(@body pet: MergePatchUpdate<Pet>): void;
```
Or, keep the old behavior by explicitly enabling implicitOptionality in the @patch options:
```
@patch(#{ implicitOptionality: true }) op update(@body pet: Pet): void;
```

Features

#7207 Implemented JSON Merge-Patch wrappers. This allows converting a type to a JSON Merge-Patch compatible update record using the MergePatchUpdate and MergePatchCreateOrUpdate templates.

Bug Fixes

#7168 Replace optional param validation requiring use with path expansion and replace with a warning when the resulting url might have a double /

1.0.0-rc.1

Features

#7049 Updates $.httpOperation.get to be a diagnosable - use $.httpOperation.get.withDiagnostics to get diagnostics
#6949 Improved types for HTTP multipart payloads for more precise guarantees and additional information about the resolution of individual parts.

Bug Fixes

#6962 Fixes issue where each variant of a @discriminated union was treated as a separate response instead of the whole union being treated as a single response.
#7069 Handle types without node
#7065 Handle tuples without nodes

1.0.0-rc.0

Breaking Changes

#6557 Remove support for deprecated implicit multipart, migrate to explicit part with @multipartBody and HttpPart<T>

op upload(
  @header contentType: "multipart/form-data",
-  @body body: {
+  @multipartBody body: {
-    name: string;
+    name: HttpPart<string>;
-    avatar: bytes;
+    avatar: HttpPart<bytes>;
  }
): void;

#6563 Separate file bodies into their own bodyKind.

The HTTP library will now return a body with bodyKind: "file" in all cases where emitters should treat the body as a file upload or download. Emitters that previously attempted to recognize File bodies by checking the type of an HTTP "single" body may now simply check if the bodyKind is "file". This applies to all HTTP payloads where an HttpOperationBody can appear, including requests, responses, and multipart parts.

Features

#6559 [API] Expose property? on HttpOperationPart
#6652 Add validation when using path or query options with the default value while the parameter is referenced in the uri template

Bump dependencies

#6595 Upgrade dependencies

Bug Fixes

#6542 Query parameter with - will be correctly represented in the resulting uri template
#6472 Path parameters can now be optional under specific circumstances. This fix updates the validation to ensure it doesn't trigger in these scenarios.

An optional parameter should have a leading / inside the {}.

For example:
```
@route("optional{/param}/list")
op optional(@path param?: string): void;
```
Another supported scenario is using @autoRoute:
```
@autoRoute
op optional(@path param?: string): void;
```

0.67.0

Breaking Changes

#6387 Removing deprecated items
isContentTypeHeader
setLegacyStatusCodeState

Moved to internal

setStatusCode
#6305 Remove deprecated items:

format option from @header and @query decorators. Use explode option instead.

-@header(#{ format: "multi"})
-@query(#{ format: "multi"})
+@header(#{ explode: true })
+@query(#{ explode: true })

shared option from @route decorator. Please use @sharedRoute instead.

-@route("/doStuff", { shared: true })
+@sharedRoute
+@route("/doStuff")

Javascript functions and typescript types:
- HeaderOptions.format
- HeaderFieldOptions.format
- QueryOptions.format
- QueryParameterOptions.format
- MetadataInfo.isEmptied
- includeInterfaceRoutesInNamespace
- getAllRoutes -> getAllHttpServices
- OperationDetails -> HttpOperation
- ServiceAuthentication -> Authentication
- HttpOperationParameters.bodyType -> body.type
- HttpOperationParameters.bodyParameter -> body.parameter
- StatusCode -> HttpStatusCodesEntry
#6433 Stop exposing APIs that were not meant for external users. Please file issue if you had legitmate use of some of those APIs.
- @includeInapplicableMetadataInPayload decorator was moved to Private namespace and stop exposing the accessor.
- Functions used in getHttpOperation to resolve the finalized view of the http operation but shouldn't be used directly.
  - resolvePathAndParameters
- validateRouteUnique internal api used in http library validation
- Moved custom route producer related APIs to experimental with unsafe_ prefix. Those APIs are not ready for public use and will change in future.
  - DefaultRouteProducer -> unsafe_DefaultRouteProducer
  - getRouteProducer -> unsafe_getRouteProducer
  - setRouteProducer -> unsafe_setRouteProducer
  - setRouteOptionsForNamespace -> unsafe_setRouteOptionsForNamespace
  - RouteProducer -> unsafe_RouteProducer
  - RouteProducerResult -> unsafe_RouteProducerResult
  - RouteResolutionOptions -> unsafe_RouteResolutionOptions
  - RouteOptions -> unsafe_RouteOptions
#5977 Minimum node version is now 20
#6357 Changed the default content-type resolution behavior as follows:
As before, if the content-type header is explicitly specified (@header contentType: valueof string), the explicit content type is used (this behavior has not changed).
If the type of an HTTP payload body has a Media Type hint (@mediaTypeHint), that media type is preferred as the default content-type for the request.
The default content-type for TypeSpec.bytes has been changed to application/octet-stream to avoid serializing the data to base64-encoded JSON.
The default content-type for all other scalar types has been changed to text/plain (previously, it was application/json).
For multipart payloads, the default content-type of the payload has been changed to multipart/form-data if the @multipartBody parameter has a Model type and multipart/mixed if the multipart payload has a tuple type.
- The content-type of individual parts in the multipart request has been changed to be the same as for HTTP payload bodies and follows the logic described above.

Deprecations

#6464 Deprecate implicit multipart body

op upload(
  @header contentType: "multipart/form-data",
-  @body body: {
+  @multipartBody body: {
-    name: string;
+    name: HttpPart<string>;
-    avatar: bytes;
+    avatar: HttpPart<bytes>;
  }
): void;

0.66.0

Deprecations

#6130 Updates @header decorator to accept values and adds the explode option. Note that using the model expression syntax to pass in arguments, or using the format field, are now deprecated.

op example1(
-  @header({ name: "ETag" }) etag: string
+  @header(#{ name: "ETag" }) etag: string 
): void;

op example2(
-  @header({ format: "csv" }) list: string[]

```
@route("files{+path}") download(path: string): void;
```

Deprecations

#3932 API deprecation: HttpOperation#pathSegments is deprecated. Use HttpOperation#uriTemplate instead.
#3932 Deprecated @query({format: }) option. Use @query(#{explode: true}) instead of form or multi format. Previously csv/simple is the default now. Decorator is also expecting an object value now instead of a model. A deprecation warning with a codefix will help migrating.
```
- @query({format: "form"}) select: string[];
+ @query(#{explode: true}) select: string[];
```

#3190 Fix @path param mapping when spreading a record in operation parameters
#3218 Fix: @path property shouldn't be applicableMetadata if the visibility contains Read

Bump dependencies

#3169 Update dependencies

Breaking Changes

#2945 Empty model after removing metadata and applying visibility always results in "void" This means the following case have changed from returning {} to no body

op b1(): {};
op b2(): {@visibility("none") prop: string};
op b3(): {@added(Versions.v2) prop: string};

Workaround: Use explicit @body

op b1(): {@body _: {}};
op b2(): {@body _: {@visibility("none") prop: string}};
op b3(): {@body _: {@added(Versions.v2) prop: string}};

#2945 Implicit status code always 200 except if response is explicitly void

op c1(): {@header foo: string}; // status code 200 (used to be 204)

Solution: Add explicit @statusCode

op c1(): {@header foo: string, @statusCode _: 204};
op c1(): {@header foo: string, ...NoContent}; // or spread common model

#2945 @body means this is the body

This change makes using @body mean this is the exact body and everything underneath will be included, including metadata properties. If metadata properties are present on the body, a warning will be logged.
```
op a1(): {@body _: {@header foo: string, other: string} };
                ^ warning header in a body, it will not be included as a header.
```
Use @bodyRoot if you want to only change where to resolve the body from.
```
op a1(): {@bodyRoot _: {@header foo: string, other: string} };
```

#2945 Properties are not automatically omitted if everything was removed from metadata or visibility

op d1(): {headers: {@header foo: string}}; // body will be {headers: {}}

Solution: use @bodyIgnore

op d1(): {@bodyIgnore headers: {@header foo: string}}; // body will be {headers: {}}
