### Known Issues in 6000.6.4f1 - 6000.2.0b2: [Vulkan] Crash on SIGSEGV in vk::OnscreenSwapChain::AcquireNextImage when vkAcquireNextImageKHR returns VK_TIMEOUT ([UUM-153744](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-153744)) - 6000.3.14f1: [Multiplayer Play Mode] Play Mode Scenario stays in the "Deploying" state when entering Play mode with an additional Editor instance and the Vulkan graphics API ([UUM-154645](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-154645)) - 6000.6.0a2,6000.5.0b2: Resources.UnloadUnusedAssets() takes significantly longer to execute when run in a Player build ([UUM-149540](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-149540)) - : Crash on mono_log_write_logfile when more than one copy of bee_backend is running ([UUM-142773](https://issuetracker.unity3d.com/issues/crash-on-mono-log-write-logfile-when-more-than-one-copy-of-bee-backend-is-running)) - : Crash on mono_log_write_logfile when opening specific project ([UUM-150566](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-150566)) - : [WinEditor] Play Mode framerate drops significantly when moving the mouse cursor with high polling rate ([UUM-142550](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-142550)) ### 6000.6.4f1 Release Notes #### API Changes - Scripting: Added: New public API, `Detach(node)` and `DetachChildren(node)` on `Hierarchy` and `HierarchyCommandList`. A detached node keeps its data map entry but is unreachable from Root. - Scripting: Added: New public API, `IHierarchyNodeTypeHandlerViewModelState`, and `GetOrCreateHandlerState`, `TryGetHandlerState` and `DestroyHandlerState` on `HierarchyViewModel`, for node type handler state that belongs to a single view model. `HierarchyNodeTypeHandlerBase.SearchBegin`, `SearchMatch` and `SearchEnd` gained overloads taking the `HierarchyViewModel` running the search. - Scripting: Deprecated: `HierarchyNodeTypeHandlerBase.SearchBegin(HierarchySearchQueryDescriptor)`, `SearchMatch(in HierarchyNode)` and `SearchEnd()` are obsolete. Use the overloads that take a `HierarchyViewModel`, since handlers are shared by every view model on a hierarchy. #### Fixes - 2D: Fixed the Open Tile Palette button and Tilemap Focus dropdown not filling the full width of their Scene view overlay. ([UUM-151417](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-151417)) - 2D: Fixed the Sprite Frame field edit lock override info box in Project Settings > Sprite Editor staying visible after the checkbox automatically unticks itself when the Sprite Editor window closes.

([UUM-152530](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-152530)) - AI: The `sourceBounds` from a NavMeshData object generated far from origin were incorrectly including the origin.
