New Tor Stable Release Adds v3 Onion Balance Support, Many Improvements

Tor 0.4.4.5 is the first stable release in the 0.4.4.x series, coming exactly four months after Tor 0.4.3.5. It brings some important enhancements, such as the implementation of the HiddenServiceOnionBalanceInstance option in the torrc configuration file to enable v3 onion services to act as backend instances for OnionBalance, the Tor load balancer. This release also replaces the 148 fallback directories from previous releases with a list of more recent 144 fallbacks generated in July 2020, re-implements support for GUARD NEW/UP/DOWN control port events, and improves the guard selection algorithms to address load balancing issues with older versions and improve security.
