- Upgrade to 4.15-2 tarball with the following release notes:
 - Fix SQUID_COMPRESS_LOGS=false, which was broken since 4.13-3.  Change
    it to also use the external logrotate command instead of the squid
    builtin log rotation.

- Filter out unneeded python3 dependency added by rpm's automatic
  dependency generation, by overriding /usr/lib/rpm/redhat/find-requires macro.

- Upgrade to 4.13-1tarball with the following release notes:
 - Update to squid-4.13 with release announcement at
     https://www.mail-archive.com/squid-announce@lists.squid-cache.org/msg00117.html
    It includes a couple of relevant security advisories related to
    cache poisoning.
 - Remove patch for bug 5051 since it is included in the 4.13 release.
- Remove the recursion on the restorecon for SELinux in the %post install
    step, to avoid taking a long time when going through a large cache.

- Upgrade to 4.12-2 tarball with the following release notes (from 4.12-1
   and 4.12-2):
 - Update to squid-4.12 with release announcement at
     https://www.mail-archive.com/squid-announce@lists.squid-cache.org/msg00114.html
    It includes a couple of security advisories, but the are on
    features that as far as I know are not used by frontier-squid users.
 - Remove patches for bug #5030 and #5041 which are included in 4.12
 - Slightly update patch for bug #5051 as recommended by squid consultant
 - Note that an additional, more relevant squid advisory fixed in 4.12 was
    published late:
     https://www.mail-archive.com/squid-announce@lists.squid-cache.org/msg00116.html
 - Support the "stdio:" prefix for access_log

- Upgrade to 4.11-3 tarball with the following release notes:
 - Apply patch for bug #5051 which prevents a negative cache from
    persisting indefinitely with if-modified-since and collapsed forwarding.
 - Fix shoal when there are multiple squid workers.
 - Add cc.*\.in2p3\.fr to MAJOR_CVMFS.  It was already in ATLAS_FRONTIER
    so it was included for installations that accept both, but not for
    those that accept only MAJOR_CVMFS.

- Upgrade to 4.11-2 tarball with the following release notes:
 - The 4.11 release announcement is now at
     https://www.mail-archive.com/squid-announce@lists.squid-cache.org/msg00108.html
    The announcement was delayed because security vulnerabilities were
    being double-checked.
 - frontier-squid was not susceptible to the ESI vulnerability, because of
    missing libraries on the build machine.  Add --disable-esi to make
    sure it doesn't get accidentally enabled.

- Upgrade to 4.10-3 tarball with the following release notes:
 - Update patch for squid bug #5022 to final version.
 - Add patch for squid bug #5030 which reported that negative caching
    was not working.  This is an important feature for keeping load
    down on CVMFS stratum 1s that are not hosting a repository.

- Upgrade to 4.10-1 tarball with the following release notes:
 - Update to squid-4.10, with release notes at
    https://www.mail-archive.com/squid-announce@lists.squid-cache.org/msg00103.html
   including a fix for a serious security vulnerability affecting
   reverse proxies and a potential information leak when proxying ftp.
 - Remove patch for bug #4735, as it has been included in the 4.10 release.
 - Change compressing log rotation back to use copytruncate when there
   are multiple workers, because the reconfigure signal triggers an
   SNMP bug when there are multiple workers (squid bug #5022).
 - Disable log rotatation when SQUID_MAX_ACCESS_LOG=0.  Using this is
    highly discouraged since standard logrotate is usually unable to
    keep up with the high volume of logs typically generated by squid.
    It also interferes with frontier-awstats support.
 - Change log rotating cron scripts to ignore commented lines in
    /etc/sysconfig/frontier-squid

- Upgrade to 4.9-2 tarball with the following release note:
 - Fix bug in daily cron that prevented it from rotating any logs

- Upgrade to 4.8-2 tarball with the following release note:
 - Add support for starting and stopping shoal-agent when installed and
   enabled by SQUID_AUTO_DISCOVER=true
- Add compilation and installation for shoal-agent

- Upgrade to 4.8-1 tarball with the following release notes:
 - Update to squid-4.8 with release notes at
    https://www.mail-archive.com/squid-announce@lists.squid-cache.org/msg00096.html
   There was no 4.7 announcement but here's the ChangeLog:
