Issues Resolved

General
Addressed potential PDF File Parsing Vulnerability in Revit. More details.
API Extensible Storage
Fixed an issue where all families in a workshared project were getting borrowed when deleting schema entities through the API.
Improved the stability when using an older Revit 2024 version with incorrect schemas in workshared projects.
Background Processes
Improved the stability of background colorfill operations when the design option is changed.
Content Browser
Improved Load Autodesk Family error messaging.
Graphics
Fixed an issue so that floors overridden with linear surface patterns and transparency display correctly on screen and in print in structural disciplines.
Link RVT Files
Improved behavior for cases where it is not necessary to generate a link model _backup folder when a worksharing-enabled Revit link is only being loaded. If the legacy behavior is preferred, it can be enabled with Revit.ini [Backups] setting DisableSkipBackupFolderCreationWhenLoadingLink=1.
MEP Fabrication
Fixed an issue where users could edit MEP elements in groups without entering the group editor.
Fixed an issue where Loaded Additional Parts were becoming orphaned when updated with MPCE.
MEP Miscellaneous
Fixed an issue where the P&ID drawing failed to load when using the P&ID Modeler.
Print
Fixed an issue where cropped generic annotations nested in model families that touched the crop incorrectly appeared when printing to PDF with the vector option.
Revit Cloud Model (workshared)
Fixed an issue where the application would sporadically close after opening a cloud workshare model.
Schedules
Fixed an issue with schedules that prevented some Revit projects from being upgraded to Revit 2024.
Units
Fixed an issue in which for some models, duplicate unit symbols were shown for some units in the Project Units dialog and parameter values that used the duplicate units could not be modified.
View
Fixed an issue which stopped view references from drawing on placement.
Improved stability when opening cloud projects with links.
