 Changes in version 0.4.5.6 - 2021-02-15
   The Tor 0.4.5.x release series is dedicated to the memory of Karsten
-  Loesing (1979-2020), Tor developer, cypherpunk, husband, and
-  father. Karsten is best known for creating the Tor metrics portal and
-  leading the metrics team, but he was involved in Tor from the early
-  days. For example, while he was still a student he invented and implemented
-  the v2 onion service directory design, and he also served as an ambassador
-  to the many German researchers working in the anonymity field. We loved him
-  and respected him for his patience, his consistency, and his welcoming
-  approach to growing our community.
