  script_tag(name:"insight", value:"This update for chrony fixes the following issues:
  Chrony was updated to 4.1, bringing features and bugfixes.
  Update to 4.1

  * Add support for NTS servers specified by IP address (matching Subject
         Alternative Name in server certificate)

  * Add source-specific configuration of trusted certificates

  * Allow multiple files and directories with trusted certificates

  * Allow multiple pairs of server keys and certificates

  * Add copy option to server/pool directive

  * Increase PPS lock limit to 40% of pulse interval

  * Perform source selection immediately after loading dump files

  * Reload dump files for addresses negotiated by NTS-KE server

  * Update seccomp filter and add less restrictive level

  * Restart ongoing name resolution on online command

  * Fix dump files to not include uncorrected offset

  * Fix initstepslew to accept time from own NTP clients

  * Reset NTP address and port when no longer negotiated by NTS-KE server

  - Ensure the correct pool packages are installed for openSUSE and SLE
       (bsc#1180689).

  - Fix pool package dependencies, so that SLE prefers chrony-pool-suse
       over chrony-pool-empty. (bsc#1194229)

  - Enable syscallfilter unconditionally [bsc#1181826].
  Update to 4.0

  - Enhancements

  - Add support for Network Time Security (NTS) authentication

  - Add support for AES-CMAC keys (AES128, AES256) with Nettle

  - Add authselectmode directive to control selection of unauthenticated
           sources

  - Add binddevice, bindacqdevice, bindcmddevice directives

  - Add confdir directive to better support fragmented configuration

  - Add sourcedir directive and 'reload sources' command to support
           dynamic NTP sources specified in files

  - Add clockprecision directive

  - Add dscp directive to set Differentiated Services Code Point (DSCP)

  - Add -L option to limit log messages by severity

  - Add -p option to print whole configuration with included files

  - Add -U option to allow start under non-root user

  - Allow maxsamples to be set to 1 for faster update with -q/-Q
           option

  - Avoid replacing NTP sources with sources that have unreachable
           address

  - Improve pools to repeat name resolution to get 'maxsources' sources

  - Improve source selection with trusted sources

  - Improve NTP loop test to prevent synchronisation to itself

  - Repeat iburst when NTP source is switched from offline state to
           online
