Hi folks,

I've been wanting to upgrade my version of SpamAssassin from
stable/Sarge to testing/Etch for a while now.

I've already upgraded MailScanner from 4.41.3-2 (stable) to 4.51.5-1.1
(testing) without any issues.

However, looking through the archives I've stumbled on many posts
mentioning problems with MailScanner after updating from SA 3.0.x to 3.1.x.

So my question is pretty straightforward, will I run into problems when
upgrading SpamAssassin from 3.0.3-2sarge1 (stable) to 3.1.7-1 (testing)?
Ie. different config file formats, different defaults, buggy behaviors,
etc? (I've just have a nice surprise when upgrading Dovecot which
grounded me all morning yesterday ... )

Basically, should I plan this when I have loads of time on my hands or
can I trust the upgrade to be smooth?

Thanks for the tips
