- Added constants to Real-Time enumeration RTX64_MONITOR_CONTROL_OP:
- MONITOR_CONTROL_ENABLE_COMPONENTS – transiently toggles generation of monitoring events by one or more RTX64 product components.
- MONITOR_CONTROL_GET_ENABLED_COMPONENTS – retrieves the transient configuration of RTX64 product components that currently have monitoring event generation enabled.
- MONITOR_CONTROL_PAUSE – pauses collection of monitoring events during the current session without having to create a new session file.
- MONITOR_CONTROL_RESUME – resumes the monitoring session from a Paused state.

Notes
General
- Members of RTX64Users cannot stop the RT-TCP/IP Stack. (1386)
Installation
- IntervalZero cross-signs INF files with a SHA-2 certificate, which requires Windows patch KB3033929 on Windows 7 systems. If this patch is not already installed, the RTX64 Runtime will install the patch automatically. Installation of this patch requires a reboot before the RTX64 installation can complete. (6905)
- The Repair feature of the RTX64 SDK installer has been removed. (7412)
Tools and Utilities
- Monitor event Shutdown Handler Call has been deprecated and will be removed from a future release. (5038)
- When the Stack Ideal Processor and/or the Stack Timer Processor value is invalid, the value(s) are automatically reset to their default setting when you navigate to the Configure RT-TCP/IP Stack Performance page in the Control Panel. You are then prompted to restart the RT-TCP/IP Stack. (7731)
NOTE: This behavior may occur elsewhere in the Control Panel with other settings. Please contact Support if similar issues are encountered.
SDK
- When RtCreateProcess is called by a Windows application linked to RTX64, it will return ERROR_NOT_SUPPORTED when parameter dwCreationFlags is set to CREATE_SUSPENDED.
- Managed Code support for the following APIs has been deprecated:
- RtGetTimer (5204, 1306)
- AttachShutdownHandlers (6892)
- Enum IntervalZero.RTX64.RTAPI.Threading.Clock4 (6788)
- Method IntervalZero.RTX64.RTAPI.RTSSEnvironment.EnableInterrupts (7239)
- Method IntervalZero.RTX64.RTAPI.RTSSEnvironment.DisableInterrupts (7239)
- Enum IntervalZero.RTX64.RTAPI.IO.InterruptMode (7239)
- Enum IntervalZero.RTX64.RTAPI.IO.InterruptDisposition (7239)
- Class IntervalZero.RTX64.RTAPI.IO.RTInterruptHandler (6891)
Samples
- The Release and Debug build configurations were not supported in the RDTPerformance sample have been removed from that sample. (7469)
Known Issues
Subsystem
- Starvation timeout does not occur if there are processes on the same core running timers/interrupts with a higher priority than that of the potential runaway thread. The RT-TCP/IP Stack is an example of such a process. If the Stack is running, and a tight loop of a normal priority is running on the same core, starvation timeout will not occur, as the context switch is still occurring to one of the Stack timers. To avoid this problem, run the tight loop on a different core than the one on which the process with the timer/interrupt is run. (7410)
Tools and Utilities
- An unhandled exception occurs when a Windows user who does not have Administrator privileges attempts to restart the Subsystem through the RTX64 Control Panel. (7465)
SDK
- The Visual Studio compiler generates a C4564 warning when the compiler warning level is set to 4 and when using C++/CLI managed code where values are not explicitly specified for default parameters. (4967)
-
The VSIX package for Visual Studio 2017 15.8 support (RTX64VSSupport.vsix) fails to install on German editions of Windows 10 version 1809. To work around this issue, install Visual Studio 2017 15.9. (7535)
