Changes since 2.5x:

- spamd now supports UNIX-domain sockets for low-overhead scanning, thanks
  to Steve Friedl for this.  Strongly recommended if you're running spamc
  on the same host as the spamd server

- DNSBLs overhauled; lots of new lists, including SORBS and SpamCop BL;
  dropped Osirusoft due to their retirement, brought on by a DDOS

- better support for detecting 'invisible text' in HTML messages

- new Bayes tweaks -- tokenization of partial address and URI elements

- RBL timeouts are now handled much more efficiently; if one RBL is taking
  much longer than all the others, it will be cut short and ignored

- now reduces amount of IP addresses queried, by inferring trust relationships
  between Received headers; trust can be manually specified using
  "trusted_networks"

- generalised Received-header parser to more easily detect HELO string
  forgery and faked relay lines

- default report updated to list the hostname of the machine where
  SpamAssassin is running; also asks installer for administrative address
  or URL, to reduce user confusion

- "add_header": more flexible header rewriting, with a simple template system

- workaround for red hat kernel with NPTL reporting "application bug" in
  spamd due to use of waitpid() when SIGCHLD is set to SIG_IGN

- dccifd support added

- Razor 1 support dropped

- support for domain-based blacklists

- new bayes backend, including new database format, ability to learn messages
  to the journal, etc.  Improved expiration mechanism

- lots of bugs fixed and new rules added. ;)


Bayes FYI: 2.60 has a new Bayes backend and database format.  Your old
database(s) will automatically be upgraded the first time 2.60 tries
to write to the DB, and any journal, if it exists, will be wiped out
without being synced.

In addition, we have had to drop support for Bayes databases in formats
other than DB_File, due to a large number of serious issues (including
crash and concurrency bugs) with those formats.

So, what you want to do is something like this:

- stop running spamassassin/spamd (ie: you don't want it to be running
  during the upgrade)
- run "sa-learn --rebuild", this will sync your journal.
- upgrade SA to 2.60
- install DB_File module if necessary
- if you were using another database module, run "sa-learn --import"
  to migrate the data into new DB_File files
- run "sa-learn --rebuild", this will cause the db format to be upgraded
- start running spamassassin/spamd again

Obviously the steps will be different depending on your environment,
but you get the idea. :)

Bayes FYI 2: Because of the new database format, "check_bayes_db" will
no longer function properly.  The functionality from that script was
added to sa-learn via the "--dump" parameter.  Please see the sa-learn
man/pod documentation for more info.


Changes since 2.60 rc2:

- bug 2334: trusted network inference ignores 'local tests only'

- bug 2370: removed support for non-DB_File database modules in Bayes

- bug 2365: Osirusoft rules dropped

- bug 2356: report_safe_copy_headers was broken

- bug 2338: Razor static srand() worked around

- bug 2360: Bonded Sender queries changed zone

- bug 2347: add_header did not support multiple newlines

- bug 2354: header options now more backward-compatible

- bug 2359: "make install" logic for non-standard PREFIXes broken
