We will be implementing the new LeftHandNav style during the period from 12/15 through 1/15. During that period we will not update your navigation entries. If you wish to have them updated, please contact us with your changes before 12/15.

Also be aware that your LeftHandNavigation may appear wrong or strange on the integration server during that time period. The navigation should remain unaffected on your live sites. Please let us know if that is not the case.
