The DrizzlePac package includes tasks used for aligning and drizzling images taken with the Hubble Space Telescope imagers. We present this release which includes new features that facilitate image alignment, sky matching, and adds support for new time dependent distortion solutions of the ACS instrument. The TweakReg task now includes capabilities for automatically aligning images which form part of a mosaic. In addition, new parameters make it easier to reject cosmic rays and other contaminants from source catalogs used for alignment. The AstroDrizzle task has been improved with a better sky measuring and matching algorithm which makes producing mosaics easier than ever before. This version of AstroDrizzle is able to implement both the new and old time dependent distortion solutions that the ACS Team has developed. There are also improvements to the GUI interfaces and some behind the scenes bug fixes.
