From 2925d8357319c9872d570fe045c883a25891b59e Mon Sep 17 00:00:00 2001 From: Michael Adam Date: Sun, 20 Jan 2008 03:24:13 +0100 Subject: Add a registry backend current_version that replaces the former dynamic overlay. Make sure to only respond to the exact current version key since subkeys are registered by other backends (printing and - soon - perflib).
