Security issues fixed:
- CVE-2017-7435, CVE-2017-7436, CVE-2017-9269: Fix GPG check workflows,
 mainly for unsigned repositories and packages. (bsc#1045735, bsc#1038984)
Bug fixes:
- Re-probe on refresh if the repository type changes. (bsc#1048315)
- Propagate proper error code to DownloadProgressReport. (bsc#1047785)
- Allow to trigger an appdata refresh unconditionally. (bsc#1009745)
- Support custom repo variables defined in /etc/zypp/vars.d.
- Adapt loop mounting of ISO images. (bsc#1038132, bsc#1033236)
- Fix potential crash if repository has no baseurl. (bsc#1043218)
zypper:
- Adapt download callback to report and handle unsigned packages.
 (bsc#1038984)
- Report missing/optional files as 'not found' rather than 'error'.
 (bsc#1047785)
- Document support for custom repository variables defined in
 /etc/zypp/vars.d.
- Emphasize that it depends on how fast PackageKit will respond to a
 'quit' request sent if PK blocks package management.");
