+2020.81 - 29 October 2020
+
+- Fix regression in 2020.79 which prevented connecting with some SSH 
+  implementations. Increase MAX_PROPOSED_ALGO to 50, and print a log 
+  message if the limit is hit. This fixes interoperability with sshj 
+  library (used by PyCharm), and GoAnywhere.
+  Reported by Pirmin Walthert and Piotr Jurkiewicz
+
+- Fix building with non-GCC compilers, reported by Kazuo Kuroi
+
+- Fix potential long delay in dbclient, found by OSS Fuzz
+
+- Fix null pointer dereference crash, found by OSS Fuzz
+
+- libtommath now uses the same random source as Dropbear (in 2020.79 
+  and 2020.80 used getrandom() separately)
+
+- Some fuzzing improvements, start of a dbclient fuzzer
+
 2020.80 - 26 June 2020
 
 - Don't block authorized_keys logins with no-X11-forwarding or no-agent-forwarding
