Whats New
Alert Output support for JSON and ZeroMQ
Syscheck improvements
Report file deletion, even without realtime enabled
Report modifications made on directories
Corrects bug so that files created between the first and second scan are reported as new files
Corrects bug that made changes reverting a file to the state it was in when ossec started unreported
Avoids computing hashes multiple times to improve performance
Make the time between two syscheck wakeups configurable in internal_options
Add support for the “nodiff” option when using report_changes, sensitive files tagged with in ossec.conf will not have their contents included in an alert.
IPv6 support
Support to call an external mailer. This solves the problem of supporting encryption when sending mail alerts in OSSEC. The <smtp_server> field can now be prepended with “/” to designate a local binary. Example: “<smtp_server>/usr/sbin/sendmail -t</smtp_server>”.
