    Additionally, the following non-security issues have been fixed:

    - Add external helper ext_session_acl to package. (bsc#959290)
    - Update forward_max_tries to permit 25 server paths With cloud sites
    becoming more popular more CDN servers are producing long lists of IPv6
    and IPv4 addresses. If there are not enough paths selected the IPv4 ones
    may never be reached.
    - squid.init: wait that squid really dies when we kill it on upgrade
    instead
    of proclaiming its demise prematurely (bnc#963539)
