The first fix pack for DB2 10.5 has been released, it is available on the
DB2 fix pack page (FPs by version). The DB2 Information Center has been updated and you find the so-called
Fix Pack Summary here. There are not many entries in what is new, but there are many improvements "under the cover". If you have never tried DB2 10.5 you can
download a DB2 evaluation copy - it is on the new code level 10.5.0.1 as well.
