What's changed since 2.61?

[Robert Nicholson]

Hi,
I've been out of the loop for a while and I was wondering if any 
signficant changes have happened since 2.61 and whether I would likely 
be introducing any incompatibility issues by upgrading.

Currently I'm programatically invoke Spamassassin from within a 
perlscript that processes my incoming email and I use Mail::Audit to 
filter mail in Maildir style mailboxes and explicitly learn mail and 
either ham or spam.

use Mail::Audit qw(List KillDups);
use Mail::SpamAssassin;
use Mail::SpamAssassin::NoMailAudit;
use Mail::SpamAssassin::PerMsgStatus;
my $spamtest = new Mail::SpamAssassin({
    PREFIX => $PREFIX,
    DEF_RULES_DIR => $DEF_RULES_DIR,
    LOCAL_RULES_DIR => $LOCAL_RULES_DIR,
   });
my $mail = Mail::Audit->new(
  nomime=> 1,
  emergency=>"$maildir/.emergency/",
  loglevel=>2,
  log=>$log
);
Because I'm using Mail::Audit I often have to construct NoMailAudit's 
from SA and visa versa.

sub noma_from_string_or_arrayref {
  my $arrayRef = (ref $_[0] eq 'ARRAY') ? $_[0] : [ split /^/m, $_[0] ];
  my $no_audit = Mail::SpamAssassin::NoMailAudit->new ('data' => 
$arrayRef);
  return $no_audit;
}

sub ma_from_string_or_arrayref {
  my $arrayRef = (ref $_[0] eq 'ARRAY') ? $_[0] : [ split /^/m, $_[0] ];
  my $mail_audit = Mail::Audit->new(
    nomime=> 1,
    emergency=>"$maildir/.emergency/",
    loglevel=>2,
    log=>$log,
    data=>$arrayRef);
  return $mail_audit;
}
my @matched_lines = fetch_message_from_imap($msgid,$spam);
my $learnmail = noma_from_string_or_arrayref([EMAIL PROTECTED]);
log_text($mail, "    Learning previously learnt spam as ham\n\n");
my $learn_status = $spamtest->learn($learnmail, undef, 0, 0);
