=====================
**available starting:** Dec 10, 2012
- ``tweakreg`` v1.1.0 source finding algorithm now runs many times faster
(no algorithmic changes). No changes have been made yet to speed
up the 2d histogram source matching code.
- The 'pixtopix' task was updated to make the 'outimage' parameter optional
by using the input image as the default. This required no API changes, but
the help files were updated.
- Very minor update to guard against MDRIZTAB being specified without
any explicit path.
- Update ``astrodrizzle`` to correctly report the exposure time,
exposure start, and exposure end for the single drizzle products,
in addition to insuring the final drizzle values remain correct.
- ``astrodrizzle`` also includes initial changes to safeguard the C code
from getting improperly cast values from the configObj(TEAL) input.
