2.9.0-1
  - New upstream version 2.9.0
  - Icinga Studio was removed from upstream
  - The package is no longer a split package as most of the libs are now linked
    into the icinga2 binary

2.8.2-1
  - New upstream version 2.8.2, including security fixes for:
    - CVE-2017-16933: chmod on user-writable symlinks, allowing privilege
      escalation.
    - CVE-2018-6532: Denial of service by memory exhaustion if the API
      component is enabled.
    - CVE-2018-6533: Possible privilege escalation via init.conf.
    - CVE-2018-6534: Denial of service due to a NULL pointer dereference.
    - CVE-2018-6535: API lacks a constant-time password comparison.
    - CVE-2018-6536: (not affected when using systemd) The init.d script kills
      a PID supplied by the icinga user as root.
  - As the update removes /etc/icinga2/init.conf, you have to update
    /etc/default/icinga2 if you changed the user or group in init.conf.
