🌵 New Cactusd Release - v.0.1.7
 
Cactusd currently has multiple uses - download > aggregate > compress and sort and then merge to one block and allow domain/IP lists from Internet and finally publish lists in own embeded web server.

Now I want to present new few features:
- Upload server (as example: you can upload own IP lists from servers manually or with ip2drop.py to Cactusd which will merge and publish tis lists as dropped_ip.txt list)
- Now you can view size for published files on web server
- Now Cactusd can configure and ping remote servers with different ports (like as 53, 443, 853 and etc)
- Ping status results displayed on Cactusd web page
- Cactusd written on Go and now you cant simple implement cactusd binary in to systemd unit service
