  the project.
- Fixed an issue that occurred when using RTE intervention services with enable
  signals.

  threads.
- Startup behavior for multi-core OS simulation in V-ECU FMUs is now
  AUTOSAR-conformant, allows the use of startup code dependent on the currently
  executing core, and waits for all AUTOSAR cores to start the OS before executing.
- Shutdown behavior of the OS for V-ECU FMUs is now AUTOSAR-conformant in terms of
  synchronization and shutdown hook execution.
- Fixed a problem with Eth Code generator, to generate the correct Service_ID for
  the communication with Det Modul.

Validation

  verification to increase flexibility.

  and exported correctly.

  composition diagram used a port interface mapping with an invalid sub element
  mapping.
- Fixed a problem where the EcuConfiguration was not visible in the
  EcuConfiguration Manager when splitting packages in the EcuConfiguration.
- Fixed a problem where the compu method dialog did not displayed the limits of a
  compu scale and set it with -INF..INF by default.
- Fixed a problem that arrays of structured elements had lost their array
  information.
- The A2L export has been extended. Compu methods of the category TAB_NOINTP and
  TAB_INTP can be exported.

- Fixed a problem where SystemDesk could crash when setting the reference to the
  OperationInvokedEvent in an EcuInstance.

  port with the same name as the source port.

Simulation
- Added new FmiAd, Sab, Os and XCP library files to support new VEOS 24.1 GCC
  compilers (Windows and Linux).

Other
- Fixed a problem with the creation of record layout after importing an A2L file,
  in case the relevant application data type of record layout has category val_blk.
- Fixed a problem when the denominator of compuScale of compuMethod is zero.
- The path to the master file list is now stored relative to the SystemDesk project
  file.
- Fixed a problem with hierarchical messages after exporting the A2L file.
- Fixed a problem where RTE generation was not possible when constant references
  with multiple levels of indirection were used (Message: "The specified data type is
  not supported").
