Existing config not compatible with DNSCrypt v2.1.1

The latest build of DNSCrypt fails to load due to config changes that the GUI is unaware of.
This means that the service will fail to load.
Once I enabled the error logging I got his error;
[FATAL] Unsupported key in configuration file: [daemonize]

Once manually removed from the config it will load, but if the UI is used to update the settings it will put it back.
Now it works I see other config error relating to blacklists;
[NOTICE] Use of [blacklist] is deprecated - Update your config file

However, my existing blacklist still seems to be loaded
[NOTICE] Loading the set of blocking rules from [C:\Program Files\bitbeans\Simple DNSCrypt x64\dnscrypt-proxy\blacklist.txt]

Looks like the next update will have to sanitise the config, or notify the users they need to reset the config, or do a clean install.
