We update our CHEP06 presentation on the ATLAS experiment software infrastructure used to build, validate, distribute, and document the ATLAS offline software. The ATLAS collaboration's computational resources and software developers are distributed around the globe in more then 30 counties. The ATLAS offline code base is currently over 5 MSLOC in 10000+ C++ classes organized into about 1700 packages. More than 600 developers contribute code. Since our last report, we have developed a powerful, flexible system to request code versions to be included in software builds, made changes to our software building tools, created a system of nightly builds to validate significant code changes, improved the tools for distributing the code to our computational sites around, and made many advancements in our tools to document our code.


This talk is intended to be a high level (over arching) talk on the work done
by the ATLAS Software Infrastructure Team (SIT) in the last two years.
