Known issues
HQN-386003 - Correct MPS not to exceed the process' maximum number of mappings on Linux
it was found that the default max_map_count on Ubuntu and Red Hat was not sufficient to allow some jobs to complete normally even with a huge memory of 120Gb. The workaround is to set max_mem_count to 1048576, which prevents this stuck loop at the end of the job. Scheduled in 14.1.
HQN-385981 - Cannot use /NumDisplayLists 2 with 'shared memory' backends
When using /NumDisplayLists 2 in conjunction with an HVD TestConfig for GG_HHR_FRAMETIFF_SHM_ERR2 Rip can hang shortly after the HVD scan. We’re advised against doing this see release notes for v14.0r0.
HQN-385923 - Scalable crashes on startup on PCs with CPUs without AVX2 support
Running a scalable RIP on an Ubuntu VM without AVX2 SIMD support can result in a crash from ZeroMQ initialising static data. Checking the CPU flags for the VM revealed it did not have AVX2 enabled.

Changes to Windows Code Signing Process
Harlequin releases will revert to internal signing for Windows builds after this release, 14.0r3. This change does not prevent OEMs from being Windows OS signed later for your customers. More details - https://learn.microsoft.com/en-us/windows/apps/develop/smart-app-control/overview . Code signing will be required if admin rights are needed to run the RIP.
The observed effect on Windows will depend on how the Windows security environment has been configured.
