This one will be probably the last major feature update for a while.
Access List functionality has been added.
Each domain and subdomain can have its own access list added, which restricts access to it via a static list of IP addresses
Useful if you want certain domains to only be accessable internally, or externally via a CDN or specific sources.
Only static IP addresses are supported.
There have been a few small bug fixes and readability fixes, nothing major though.
There is one change in functionality, in v1.2.0 the empty handles have been placed last automatically. This functionality had to be removed in v1.3.0 in favor of nested access lists. You have to order your handles in the right order yourself in the GUI. If you only had empty handles before this change doesn't affect you.
