[opencms-dev] Critical bug in all version >7.5.4

Thu Jan 19 15:16:25 CET 2012

Hi Georgi,

the change does not effect the data within the database. The problem comes with case insensitive string comparison. Within the slightly delicate rename/move operation case sensitivity is very important.

Greetings, Tobias
