Just went after an upgrade for the windows version from 0.71 to 0.80 - anything fine, apart for one thing. I didn't see any hint on how to preserve former configurations, so I copied my configuration files from /program files/config to /application data/../config.
When I try to load one of them, all "replace" renamings have disappeared - only one empty "replace" is present. Subsequent "insert" do not show up as well.
Attached you'll find a very simple 0.7x version of one of my configs: it contains 3 modifications (all fine), 5 replaces (all missing) and 1 insert (missing as well). Attached as well, an extract from the logfile, showing some rants about a missing ReplaceToolsPanel attribute.
