Tornevall Networks has plans to deprecate v3.x of the current TorneAPI-package. One of many reasons is that many functions are still bound to the netcurl 6.0-series – one other reason is an upcoming RSS-interface. There are also efficiency issues within the API that has been a problem. Not publicly but for internal perfomance. The first plan was to go APIv4, but instead there could be a major change – a reboot. Version 3 will remain in place, to handle DNS requests until there’s a new stable.
With this deprecation change, the DNSBL will got itself a major issue: Removals are now forced. This also means that a full removal procedure will be sent to the DNS even if the requested IP address is not confirmed listed.
