+portage-2.1.4
+==================================

+* Visibility filtering is now supported for binary packages, so masking behavior
+ is essentially equivalent to that of ebuilds.
+* There is no need to have a complete portage tree available when installing binary
+ packages or uninstalling packages, but a warning message will still be displayed if
+ it appears that a valid profile is not available.
+* The emerge --search action supports searching of both installed and binary packages
+ The --usepkg and --usepkgonly options control which repositories are searched.
