Release Notes

(REQUIRED)

The normalizeFlags function is redundant and causes the value.Set to be triggered for every alias which in turn increments count for flag unnecessarily. This function is a holdover from very very old code and has been removed. This fixes the count issue and also allows multiple aliases of same flag to be used without any errors.
