-## Version Notes:
-- 5.0.12: DEVELOPMENT
+## Version History
+
+#### Development Build:  5.0.13
+  - Added coverage test to `OS_TimerCreate` for `OS_ERR_NAME_TOO_LONG`.
+  - Externalize enum for `SelectSingle`, ensures that pointers passed to `SelectFd...()` APIs are not null, ensures that pointer to `SelectSingle` is not null.
+  - Command to run in shell and output to fill will fail with default (not implemented) setting.
+  - Builds successfully using the inferred OS when only `OSAL_SYSTEM_BSPTYPE` is set. Generates a warning when `OSAL_SYSTEM_BSPTYPE` and `OSAL_SYSTEM_OSTYPE` are both set but are mismatched.
+  - See https://github.com/nasa/osal/pull/433 for more details
+
+#### Development Build:  5.0.12
   - Use the target_include_directories and target_compile_definitions functions from CMake to manage the build flags per target.
   - Build implementation components using a separate CMakeLists.txt file rather than aux_source_directory.
   - Provide sufficient framework for combining the OSAL BSP, UT BSP, and the CFE PSP and eliminating the duplication/overlap between these items.
   - Minor updates (see https://github.com/nasa/osal/pull/417)
-- 5.0.11: DEVELOPMENT
+
+#### Development Build:  5.0.11
   - The more descriptive return value OS_ERR_NAME_NOT_FOUND (instead of OS_FS_ERROR) will now be returned from the following functions (): OS_rmfs, OS_mount, OS_unmount, OS_FS_GetPhysDriveName
   - Wraps OS_ShMem* prototype and unit test wrapper additions in OSAL_OMIT_DEPRECATED
   - Minor updates (see https://github.com/nasa/osal/pull/408)
