I am considering upgrading both Postfix and MailScanner for efficiency purposes (the newer versions of both are purported to be faster), but I am wary about fixing something that isn't broken (so to speak).
The major speed increases were up to 4.50. Is 4.54 much faster than 4.51?

The current differences between 4.54.4 and the proposed 4.54.5 are 
(These give you a good idea of the stability as I have addressed every 
known problem with 4.54.4 in 4.54.5)

5 Added Net::IP Perl module as it is needed for SpamAssassin and Net::DNS.
5 Improved handling of Unicode encoded subject lines with a few trailing 
5 Fresh translation of German languges.conf file.
5 Fixed bug in sophos-wrapper caused by confusion between Sophos V4 and V5.
5 Fixed bug stopping regexp rule /^$/ from working properly in rulesets.

That is the total list of all known problems in 4.54 and improvements 
made to 4.54.5. I will release 4.54.5 as another beta (with no known 
problems at all) if you want me to.

I suspect the only thing you actually might want is the new 
sophos-wrapper which I have posted to the list already, a couple of days
