 # conn
 
+__this branch has been merged into main and is no longer maintained__
+
 quick and dirty server availability check <br> <br>
 basically just a way too complex wrapper for nmap and fping <br>
-the pre-rewrite version is available as conn.sh.old and is no longer maintained <br>
 
 ### features: 
-- ~~multi-input detection~~ (not needed anymore since the rewrite)
-- ~~ipv4 input detection~~ (not needed anymore since the rewrite)
-- ~~ipv6 input detection~~ (not needed anymore since the rewrite)
+- multi-input detection
+- ipv4 input detection
+- ipv6 input detection
 - waiting for availability
 - send notification on availability
 - updater built in
