Hi, Even though OSE 3.3 is still in a beta state, the documentation has been finally updated with the new features of syslog-ng OSE 3.3, so it contains a basic description for the mongo database support and for running syslog-ng in multihreaded mode, and a bunch of error corrections and clarifications. For a list of changes, see http://www.balabit.com/sites/default/files/documents/syslog-ng-ose-3.3-guide... The guide is available at the BalaBit Documentation Page at http://www.balabit.com/support/documentation?&product_line=46&product_type=4... , in PDF, HTML, and single-page HTML format. As always, comments, criticism, error reports, and feedback is welcome here on the list or at the documentation@balabit.com e-mail address. Kind Regards, Robert Fekete
