I upgraded to the latest version at home last night and everything ran fine. My home machine is running Ubuntu.
When I did the same on my work machine which is using Arch Linux, I'm getting the following error:
::connect() to existing APserver failed: Connection refused
*** using local Svar_DB cache
*** Failed to start APnnn: processor 1001 will not accept incoming shared variable offers. Expect surprises.
