QV11.2 SR6 Update 1 released due to bug in Hash functions.

The hash functions, Hash128, Hash160 and Hash256 has changed behavior from SR5 and with the same input now gives a different value in SR6. If these hash function are used to create concatened keys to be stored in QVD’s and used in combination with incremental loads this will lead to non-matching keys with older QVD-data. If you have already used SR6 to create QVDs according to above, these have to be recreated to match older QVD’s.

We recommend all customers that have installed SR6 to upgrade.

hi!

does this bug also affects autonumberhash128() and autonumberhash256() ?

If the hash()-functions just return different results, autonumberhash*-functions are probably not affected. Do you aggree, or are there situations where those two function also return different numbers in QV11.20SR6IR!

Thx,

Roland
