General

• Suppress command line progress bars for non-interactive terminals.
• Added Python API environment setup instructions to the documentation home page. 
• Added sample script for creating architecture in CMake
• Reduced row height in Project Configuration tables and updated the width of the first column.

Language - C/C++

• Add support for Cyclomatic Strict Modified metric collection in fuzzy C analysis
• Add Accessed By field in the Information Browser for c++ macros

Language - Fortran

• Add references to dummy arguments when named association is used in a function or subroutine call.
• Add 'local component variable' for components of local derived types.
• The Information Browser now lists a file's program units and groups a routine's nested locals under a Local section.

Language - Visual Basic

• Improved Information Browser member visibility and parameter display. Friend and Protected Friend members are now shown correctly, and Protected members no longer include Protected Friend members.
• The Information Browser now displays the containing namespace for types.
• The Parameters field now renders function signatures correctly.
• Default and parameterized properties, as well as generic classes, now display their parameters.
• Property parameters are now shown in a dedicated Parameters field instead of being grouped with Accessors.

Rust

• Add "features" settings interface

Bug Fixes

CodeCheck

• Fix issue where inspection errors weren't being restored on Windows
• Fix codecheck comment ignore parsing to strip leading and trailing whitespace.

CodeCheck Checks

• Fix: false positives in MISRA12_21.2 for reserved identifiers introduced by library macro expansion
• Fix: false positive in MISRA12_14.2 when a for loop uses different struct members in the bound and body
• HIS_02 Fix possible failure when 'CountPath' metric returns NULL
• Fix: Script error in EXP-44
• Fix MISRA23_8.9.1 false positive on pointer members vs array members

General

• Fix Information Browser visit next/previous keyboard shortcuts not working when drawered.
• Fix possible crash on exit
• Fix brace style in ExampleProjects class declaration

Language - Fortran

• Fix bug where some local entities were given long names that included the full path to the parent entity.
• Add 'local' kinds for procedures, derived types, and enumerators defined within procedures. This change fixes a bug where some unknown entities could merge with these nested entities.

Language - C/C++ Strict

• Fix invalid references to type names introduced by using declarations

Known Issues

• Loading a custom GGUF model may incorrectly report the file as corrupted. This issue does not affect the GGUF models included with Understand.
  
• AI generation may incorrectly state it has been disabled due to insufficient specs
• AI generation may use more than 6 GB of RAM in some cases. Systems with 8 GB of RAM may encounter out-of-memory errors. If this occurs, disable AI generation under Tools > Options > Data. 
• Some macros aren't defined when importing VS 2022 SLN and VCXPROJ
• Print Preview may not function correctly
