-The first version of the attribute store used a different format for
-storing information, we later merged this format with the solv file
-format.

-=== libzypp integration ===
-Integration of the sat-solver into libzypp also started in October 2007 by
-Stefan Schubert and Michael Andres from the YaST team. The first
-versions supported both the old solver and the new one by using the
-old repository read functions and converting the old package data
-in-memory into a sat solver pool. Solvers could be switched with
-the environment variable ZYPP_SAT_SOLVER. The final decision to
-move to the new solver was made in January of 2008, first just by
-making the new solver the default one, later by completely throwing out
-the old solver code. This had the advantage that the internal solvable
-storage could also be done by using the solver pool, something Michael
-Matz already played with in a proof of concept implementation showing
-some drastic speed gains. The last traces of the old database code
-were removed in February.
