Revision History

Version	Description
V2.3.0	Added provisional support for processor affinity in SMP systems: osThreadAttr_t :: affinity_mask osThreadSetAffinityMask, osThreadGetAffinityMask
V2.2.0	Added support for Process Isolation (Functional Safety): Kernel Management: osKernelProtect, osKernelDestroyClass Thread Management: osThreadGetClass, osThreadGetZone, osThreadSuspendClass, osThreadResumeClass, osThreadTerminateZone, osThreadFeedWatchdog, osThreadProtectPrivileged Thread attributes: osThreadZone, osThreadUnprivileged, osThreadPrivileged Object attributes: osSafetyClass Handler functions: osWatchdogAlarm_Handler Zone Management: osZoneSetup_Callback Exception Faults: osFaultResume Additional functions allowed to be called from Interrupt Service Routines: osThreadGetName, osEventFlagsGetName, osTimerGetName, osMutexGetName, osSemaphoreGetName, osMemoryPoolGetName, osMessageQueueGetName
V2.1.3	Additional functions allowed to be called from Interrupt Service Routines: osThreadGetId
V2.1.2	Additional functions allowed to be called from Interrupt Service Routines: osKernelGetInfo, osKernelGetState
V2.1.1	Additional functions allowed to be called from Interrupt Service Routines: osKernelGetTickCount, osKernelGetTickFreq Changed Kernel Tick type to uint32_t: updated: osKernelGetTickCount, osDelayUntil
V2.1.0	Support for critical and uncritical sections (nesting safe): updated: osKernelLock, osKernelUnlock added: osKernelRestoreLock Updated Thread Flags and Event Flags: changed flags parameter and return type from int32_t to uint32_t
V2.0.0	New API Version 2.0 available. See CMSIS-RTOS2 API for a detailed function reference.
V1.02 - only documentation changes	Added: Overview of the CMSIS-RTOS Validation Software Pack. Clarified: Behavior of Timeout Values.
V1.02	Added: New control functions for short timeouts in microsecond resolution osKernelSysTick, osKernelSysTickFrequency, osKernelSysTickMicroSec. Removed: osSignalGet. fv
V1.01	Added capabilities for C++, kernel initialization and object deletion. Prepared for C++ class interface. In this context to const attribute has been moved from osXxxxDef_t typedefs to the osXxxxDef macros. Added: osTimerDelete, osMutexDelete, osSemaphoreDelete . Added: osKernelInitialize that prepares the kernel for object creation.
V1.00	First official Release. Added: osKernelStart; starting 'main' as a thread is now an optional feature. Semaphores have now the standard behavior. osTimerCreate does no longer start the timer. Added: osTimerStart (replaces osTimerRestart). Changed: osThreadPass is renamed to osThreadYield.
V0.02	Preview Release.
