Turned on WebView2 for Studio uses on Windows compatible machines.

It is now possible to tie breakpoints to execution contexts: Edit, Client or Server.

Improved accuracy of Explosion radius.

Updated the latest version available label in the About Studio dialog whenever a new version becomes available rather than just when the dialog is first opened.

Migrated Studio specific TToolVerb to RobloxStudioVerbs and made sure its thread safe.

Added BillboardGui support for Gamepad UI navigation.

• Find And Replace Widget - Find…

The colors of these will now be the same as other parts of the Roblox Studio UI: Text boxes and dropdown lists.

Now, select() is faster when used on variadic arguments (when the second argument is ...). The gains scale with the number of variadic arguments, with 10 arguments it’s ~3x faster.

Enabling Publishing CurveAnimation assets to Roblox.

Minor improvements to InterpolationThrottling.

table.create(N, {}) will now produce a static analysis warning since the element is going to be shared for all table entries.

This change allows for a Model to obtain a highlighting effect.
This highlighting effect composes of a solid fill color and a pixel width outline effect. Both effects can have an arbitrary color and transparency.
The effect can also be selected to be visible through closer objects or only visible when the model is visible.

Add “force servers to restart” Rollout Option in “Publish As …” flow.

tostring() now uses a new cross-platform number formatting implementation that produces precise, round-trippable, shortest decimal output and does this 10 times faster than our old implementation depending on the platform and the input number.

Script analysis now warns about adding new properties to tables exported from a module.

In VR in First Person we show a vignette / edge effect to hide the motion in the peripheral vision. We added a menu option to toggle this effect on/off.

Fixed a bug where welding a part to a floor where a character was standing could cause the character to start falling for one frame.

Fixed various crashes in physics APIs.

Mutually recursive types must agree on their type parameters. (This restriction always existed, but caused random behavior if it was broken).

Logpoints now log the script name and line number where they are placed. They are also clickable, bringing them to feature parity with print-based debugging.

Implemented the new Roblox VR system with the following components:

• 3rd person and 1st person comfort camera module with vehicle support
• New in-game menu and player gui interaction
• Support for Oculus Touch and Valve Index controllers

Added a custom action in Pathway point and also did some internal code refactor which should not have impact to user.

Added APIs to override built-in terrain material appearance.

Update CanQuery Beta: Studio will now be able to select/interact with Parts set with CanQuery=false.

Added a fix for FloatCurves crashing on serialization.

The minimum playback speed is now 0.01x (changed from 0.1x).
When loading an animation, or creating a new one, the playback speed is no longer reset to 1x.

With this bugfix, when a script (or part of a script) is copy-pasted onto a selected region with the overall number of lines not changing in the script, the breakpoint markers don’t disappear any more.

Fixed BillboardGui rendering in VR.

Fixed visual issues with Bones when scaling skinned meshes.

With this bugfix, the breakpoint marker sizes follow the font size consistently between font size changes when scripts are closed and opened.

Implemented the new Roblox VR system with the following components :

• 3rd person and 1st person comfort camera module with vehicle support
• new in-game menu and player gui interaction
• support for Oculus Touch and Valve Index controllers

Improved gamepad device support.

Luau now has better heuristics for inferring types for code that has type errors, so users should see fewer unknown types now.

Made explorer scroll to the selected item after clearing filtering.

Implemented the new Roblox VR system with the following components:

• 3rd person and 1st person comfort camera module with vehicle support
• new in-game menu and player gui interaction
• support for Oculus Touch and Valve Index controllers

Implemented bit32.countlz and bit32.countrz; they return the number of consecutive zero bits in the bit representation of the input number starting from the left most (most significant) or right most (least significant) side, respectively; if the input number is zero, both functions return 32.

Added RigidConstraint, a new class of joint forming a rigid connection between two Attachments.

Leaving the tangents unset in a FloatCurve now set them to “auto-tangents”.
Previously saved FloatCurves are not backwards compatible and have to be re-authored.

Added new instance type: MarkerCurve.

Fixed a bug where Save to Roblox is disabled after publishing the current place.

Fixed a bug with how plugin IDs are created. Developers may notice plugins in a different configuration due to changes in IDs.

Fixed an error in Luau’s string.pack implementation that could fail to detect argument overflow on ARM processors.

Fixed a GUI error caused by the “Pathfinding Modifiers” beta feature.

Logpoints now log the script name and line number where they are placed. They are also clickable now, bringing them to feature parity with print-based debugging.

Provided additional details in Luau type mismatch errors pointing to specific table properties, union options or intersection parts.

Type checker now supports FindFirstAncestor when analyzing require() calls.

Additionally, in strict mode require() calls with arguments that don’t have a supported structure will produce a type error, which can be silenced with :: any annotation on the require result.

Fixed a backtrace crash for AnchorVerb on data model closing.

The correct Robux balance is shown in the success dialog after purchasing plugins.

Fixed a bug with Bones that lead to inaccurate TransformedWorldCFrame values.

New Squash property to particles for non-uniform particle stretching, curve controlled for bouncy effects.

Improve PluginManagement loading speed.

Turn off gamepad selection if the current selected button disappears.

Removed age notification in VR mode.

Luau linter now warns when table.move is used with 0 as the index.

Added common static values on Vector2/Vector3/CFrame, E.g.: Vector3.one = Vector3.new(1, 1, 1), Vector2.xAxis = Vector2.new(1, 0), and CFrame.identity = CFrame.new() (but yields the same object reference every time).

Added a new property CFrame/Rotation which is equal to the original CFrame but with the translation component set to zero.

Type checker now supports FindFirstAncestor when analyzing require() calls.

Additionally, in strict mode require() calls with arguments that don’t have a supported structure will produce a type error, which can be silenced with :: any annotation on the require result.

Improved subtyping for Luau tables.

Death state of Humanoids should replicate more consistently to clients.

Fixed a bug with Luau generic type aliases which could sometimes cause confusion between generic types which occurred in both the parameters and arguments.

Terrain Heightmap Importer will now clear the empty space inside the import box. This prevents hard to find problems caused by subtle holes sometimes appearing under the surface when iterating on the same heightmap and reimporting it without clearing the terrain in between.
Note that the pixels with value of 0 in the new heightmap are not imported at all, so this can still be used to “merge” from two heightmaps.

Fixed property display issue for LinearVelocityConstraint.

Humanoid AutoJump will now respect collision groups. The humanoid will not try to jump onto parts it cannot collide with.
