> Can anyone who have started using 8.3.1 list out the pros and cons. I upgraded to 8.3.1 yesterday from 8.3.0. I've used 8.3.0 since it was released and it's working fine. I upgraded from 7.4 (dump/restore) and it was working out of the box. We have somewhat simple sql-queries so there was no need to change/alter these. The largest table has approx. 85 mill. records (image-table). One thing I had newer seen before was that duplicate rows was inserted into our order-table but I don't know whether this is due to changes in the web-app or 8.3.0. Now that I upgraded to 8.3.1 I will wait a few weeks and see if I get the same error before I alter the column and add a unique contraint. So from a 7.4-perspective and fairly simple queries I don't see any issues. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare
