Euh, 20100331 seems to introduce regressions for me compared to 20100328.
scp now seems broken for me,

$ scp -vvvvv somefile user@example.org:/tmp/
Executing: program /usr/bin/ssh host example.org, user user, command scp  
-v -t -- /tmp/

and often just hangs there, while PuTTY's pscp and interactive ssh to the  
same host + login works just fine, and also if I'm using the 20100328  
snapshot.

With gdb attached, it succeeds once in a while.
