Version 4.3.5 has been released

[Ulf]

Just some minor improvements to keep things running smoothly.

• ICANN no longer requires Whois data to be kept up-to-date, so data quality and quantity will degrade over time; its replacement is RDAP
  
• Subnet Scan was slowed down (fewer parallel threads), so it has more time to find out extra information about each host.
  
• Added DNS4EU v4 and v6 to the default list of DNS servers. See https://www.joindns4.eu/for-public for details.
  
• Removed Quad9 and Quadrant Secure DNS providers. (Note that Secure DNS is largely obsolete at this time, since the regular DNS supports DoH endpoints.)
