This is mostly a maintenance and features update.
There are however a couple of FreeBsd specific issues:
1) sa-update now puts files into /var/db/spamassassin/{version} where it
belongs rather than in the non-standard /var/lib/spamassassin.
Thanks to uhlar@fantomas.sk (see PR: ports/108934
2) security, version minimum updates:
Compress-Zlib needs to be minimum 1.04, HTML-Parser, 3.3.1, Tar.pm,
1.2.3, gnupg >=1.4.7 (gnupg 2.x preferred)
3) additional files needed: Detect.pm for encoding, p5-Mail-SPF replaces
p5-Mail-SPF-Query, newer DKIM replaces DomainKeys
4) sa-compile is broken (need re2c >=.11.3 or it segfaults)
5) tools directory removed (find it in SVN if you need it)
6) patch files added: patch-ImageInfo.pm and patch-sa-compile.raw
7) patch files REMOVED (ports, please note:
don't need patch-sa-learn-raw anymore!
