+squid3 (3.5.12-1ubuntu4) xenial; urgency=medium
+
+  * Remove redundant version-guarded restart code from squid postinst, which
+    doesn't do the right thing on Ubuntu upgrades.
+  * Remove duplicated conffile handling from the squid3 dummy package with
+    extreme prejudice.  The conffile moving absolutely *must* be done
+    exclusively in the squid package; trying to do it in the squid3 package
+    causes pristine conffiles to be silently overwritten with any
+    locally-modified version from the squid3 package, with hilarious effect.
+  * Adjust squid.{pre,post}inst to trick dpkg-maintscript-helper into
+    believing we had a previously installed version of this package even if
+    we did not, which appears to be a requirement for mv_conffile to DTRT.
+    This is certainly a dpkg bug that needs to be filed.
+  * Move all Ubuntu-specific dpkg-maintscript-helper delta into
+    debian/squid.maintscript for clarity/sanity.  Among other things,
+    this uncovers a bug where we're trying to call both mv_conffile and
+    rm_conffile for /etc/init.d/squid3.
+  * debian/squid3.{pre,post}inst: drop wrong short-circuiting of various
+    invocations; we always want to call the debhelper block.
+  * debian/squid3.postinst: don't try to stop squid3 again, this is
+    redundant.
+  * debian/squid3.postrm: don't rm -f conffiles in purge when dpkg already
+    handles these.
+  * Add missing pre-depends on adduser
+  * Anchor the Conflicts/Replaces to the version of the package that
+    introduced the name change in Ubuntu, to avoid upgrade ordering problems
+    later.
+  * Include upgrade migration handling for /var/spool/squid3 ->
+    /var/spool/squid.  This won't work if /var/spool/squid3 is a mount point,
+    so fail gracefully, but leaving two full squid cache directories around
+    after upgrade is a nuisance.
+  * Remove empty /etc/squid3 dir on upgrade.
+  * Clean up apparmor links for usr.sbin.squid3 on upgrade.  We don't migrate
+    these apparmor settings over, so at least don't leave stale links behind.
