Then the preparations of the "wheezy" release began right before we uploaded the first 2.0.x packages to Debian. We honestly told the Debian security and release teams of our problems and hoped to find a way to keep Zabbix in Debian. And we told them that the known security problems were indeed fixed by the 2.0.x packages. But of course we were all scared to see history repeating and ship a vulnerable software with "wheezy". And the 2.0.x package was so brand new und not well tested that the release team didn't like to put it into the new release yet.
