+Subject: [PATCH 9/9] pkg_depends: fix version constraints
+
+* factor parsing version constraint to str_to_constraint and use that
+  from pkg (pkg_version_satisfied) and also pkg_depends (parseDepends)
+* fix constraint_to_str(), for EARLIER and LATER it was using '<' and
+  '>' which is parsed later as EARLIER_EQUAL and LATER_EQUAL
+* show notice when deprecated '<' or '>' is used
