Release notes for 327

Add support for Windows Mixed Reality devices

Text scraper re-uses the same GeneratedLocalizationTable over multiple runs.

Improved the look and visibility of glass on low quality mode to be more consistent with medium quality.

Significantly reduce amount of data that needs to be sent during join for terrain-heavy places

Added a button to the localization tools plugin for toggling play mode to use Spanish

Added GuiBase.RootLocalizationTable and GuiBase.AutoLocalize. Deprecated LocalizationTable.Root, which will be disabled soon.

Any Gui under PlayerGui or Workspace can use any LocalizationTable that is a child of LocalizationService to translate. If RootLocalizationTable is set that table will be used to translate that object and it's children instead. The RootLocalizationTable does not need to be a descendant of LocalizationService.

Made the purpose of the language testing buttons in the Game Locliazation Tools plugin more clear by splitting the "Spanish" button into two buttons, "Play in English" and "Play in Spanish"

Consolidating behavior of string.format across 32 and 64 bit applications (there are some combinations of format specifiers and values that are inconsistent at the moment). We will be gathering impact metrics to determine if it is safe to enable this before changing ANY behavior in game / studio, please follow posts on the dev forum for specifics.

When inserting Gui Objects, it will follow this behavior:
Insert Gui Object Behavior
If there is multiple selection, it will act on the first selected object.
If there is a selection that is ScreenGui, make it a child of ScreenGui.
If there is a selection that is any other GuiObject, make it a sibling of that GuiObject.
If no selection, insert it into first ScreenGui under Starter Gui

Fixed a bug where dragging a model out of Workspace would cause joints to sometimes be deleted.

Big places should load faster. workspace::assemble should take less time.

Fixes a crash when using a WeldConstraint that has at least one part not in the Workspace.

Fixed an issue where the sound cache would get incorrectly cleaned up, leading to errors when trying to play sounds.

User input remote events should now work for FilteringEnabled games

This method is asynchronous and returns an `Operation`, which represents the current state of the operation. It contains an endpoint path that you can poll to obtain the real response and applicable metadata. See the [documentation]({longRunningOperationsLink}) on long-running operations for more information.
            
The following sections describe the response and metadata objects that are provided when an operation completes.

Beta endpoints are ready for public use. Breaking changes are possible but rare.

These Open Cloud documentation pages will be removed on March 31, 2026. You will be automatically redirected to the new Open Cloud documentation at that time. {linkStart}Learn more{linkEnd}

These old Open Cloud pages will be removed and redirected on March 31, 2026. {linkStart}Learn more{linkEnd}

Experimental endpoints are ready for public use, but may experience breaking changes occasionally as the API contract is finalized.

This endpoint can be called in-experience through {httpServiceLinkStart}HttpService{httpServiceLinkEnd} with an API key.

This field may be set when creating a resource, but may not be modified by subsequent requests.

These fields may be set when creating a resource, but may not be modified by subsequent requests.

This field may be provided in requests, but will never be included in responses.

Legacy authentication method. Always prefer using API Key or OAuth 2.0 when available.

Per API Key: {maxInPeriod} requests every {periodInSeconds} seconds per IP Address

Requires no authentication to call. Typically has significantly lowered rate limits. Always prefer using API Key or OAuth 2.0 when available.

For each grouping, only one of the following fields in the schema has to be provided, the remaining can be excluded.

You can opt back in at any time. {linkStart}Provide feedback.{linkEnd}

You are viewing the old docs. {linkStart}Provide feedback.{linkEnd}

You can opt out at any time and be redirected back to the old reference pages. {linkStart}Provide feedback.{linkEnd}

You are viewing the revamped docs. {linkStart}Provide feedback.{linkEnd}

This field may be set on responses, but will be ignored in requests.

Note: Rate limits can be lower during high-traffic periods. Certain endpoints have additional rate limits. [Learn more about rate limits]({link}).

{limit} requests per day across all API keys for a user or group

{limit} requests per hour across all API keys for a user or group

{limit} requests per minute across all API keys for a user or group

{limit} requests per second across all API keys for a user or group

{limit} requests per minute per API key owner

{limit} request(s) per second per API key owner

Scopes control what permissions your credentials have. Your credentials can only access the endpoints supported by the scopes you selected.

Stable endpoints are production-ready and will almost never experience breaking changes during their lifetime.

This target enables you to limit your key's access to selected {requiredParts}

This target enables you to limit your key's access to selected {requiredParts} and {optionalParts}

Target types are used to restrict the resources that your credentials have permissions on. Only the selected resources can be acted on even if your account has permissions on additional resources. Some scopes do not have target parts. In these cases, all of your relevant resources can be acted on.

The universe Top Level Part does not need to be selected for user-owned API Keys. In this case, your API Key will have access to all of your user-owned experiences and group-owned experiences that you have the right group permissions on.

Try It Out is not yet supported for endpoints requiring API key or OAuth 2.0 authentication

Cookie authentication is disabled for high risk operations for safety.

Critical risk endpoints are extremely sensitive and Try It Out is disabled for safety

Note: Authentication headers are not included in this code sample. You may need to add an authentication header for this command to work.

This is a high risk endpoint that can modify or delete critical data. Use extreme caution when testing.

This API endpoint has been classified as HIGH RISK and may affect live data or user accounts.

Authenticated requests to high-risk APIs can make changes that cannot be undone. Please review your request parameters carefully before proceeding.

Please login to use cookie authentication

This is a low risk endpoint that retrieves data. This is generally safe to test.

This is a medium risk endpoint that modifies data. Test carefully with non-critical accounts, as changes may be permanent.

To keep your account safe, never paste text here from other sources or send information from this page to others.

You are about to test live API endpoints using your actual account credentials.

Only proceed if you understand the implications of the API calls you're about to make. Review the API documentation carefully before testing.

API calls will be made using your authenticated session

These are real API calls that may affect your account or data

Rate limits and other API restrictions apply

Some operations may modify or delete data
