-/*
- * Note about the OS_REVISION value:
- * During development of the "next" version of OSAL (whatever number it might be), the
- * OS_REVISION value should be something high (>90) to indicate the fact that this is a development
- * version and not an official release version.  For instance, at the time of this writing
- * the official version is 4.1.1 and the next version would likely be 4.2.0.  So anyone
- * who uses the "bleeding edge" development branch before 4.2.0 is officially released will
- * get a version that reads e.g. "4.1.91" to show that this is a pre-4.2 build.
- *
- * This still leaves room for patches to be applied to 4.1.1 to produce 4.1.2 if needed.
- *
- * During development, if an API-affecting change is introduced then the OS_REVISION value should
- * be incremented with it to indicate this.  Client code that depends on the new API can do a "#if"
- * against the development version number e.g. "#if OSAL_API_VERSION >= 40191" and this check
- * will still be valid after the version becomes 40200 (although at some point it can be cleaned
- * up to reflect the official version number, it is not going to break the build in the meantime).
