 ## Version History
 
+### Development Build: 5.1.0-rc1+dev49
+
+- Adds an event callback mechanism to certain state changes in OSAL. This allows the CFE PSP to be notified at these points, and therefore it can add platform-specific functionality.
+- Correct issues involving recent OS_Milli2Ticks change.
+- See <https://github.com/nasa/osal/pull/612>
+
 ### Development Build: 5.1.0-rc1+dev44
+
 - Removes OS_Tick2Micros and internalize OS_Milli2Ticks.
 - Adds ut_assert address equal macro.
 - See <https://github.com/nasa/osal/pull/607>
 
 ### Development Build: 5.1.0-rc1+dev38

 ### Development Build: 5.1.0-rc1+dev34

-function.
+- Move this existing function into the public API, as it is performs more verification than the OS_ConvertToArrayIndex function.
 - The C library type is signed, and this makes the result check work as intended.
 - See <https://github.com/nasa/osal/pull/596>
 
+
 ### Development Build: 5.1.0-rc1+dev16
 
  - In the next major OSAL release, this code will be no longer supported at all. It should be removed early in the cycle to avoid needing to maintain this compatibility code. This code was already conditional on the OSAL_OMIT_DEPRECATED flag and as such the CCB has already tested/verified running the code in this configuration as part of CI scripts. After this change, the build should be equivalent to the result of building with OMIT_DEPRECATED=true.
