Summary of the various changes in 3.2.0.
Please feel free to edit away, some entries are too verbose, some aren't verbose enough.
IPv6 Support
spamd: TELL commands disabled by default, use --allow-tell to enable.
bug 4589: allow M::SA::Message to use IO::File objects to read in message (same as GLOB). Also add in check to ignore unknown reference types.
bug 4517: rule instrumentation plugin hooks, from John Gardiner Myers <jgmyers /at/ proofpoint.com>
The Great Rules Directory reorg
Rule QA Stuff
bug 4363: if a message uses CRLF for line endings, we should use it as well, otherwise stay with LF as usual
spamc: Add -K option to ping spamd
Bug 4515: content preview omits first paragraph when no Subject: header
Received Header parsing updates/fixes/additions
The tflags multiple thing
bug 4700: certain privileged configuration settings can inject code, due to a bad fix for bug 3846. Back that out
add two features to core rule-parsing code; 1. optional behaviour to recurse through subdirs looking for .cf/.pre's, to support rules compilers working on rulesrc dir. 2. call back into invoking code on lint failure, so rule compiler can detect which rules exactly fail the lint check
Bump HTML::Parser minimum version to prevent errors.
sa-update stuffs
Bug 4636: Add support for charset normalization
Bug 4636: Require non-buggy HTML::Parser for charset normalization
Bugs 4606, 4609: Adjust MIME parsing limits
trusted_networks/internal_networks fixes/stuffs
bug 3109: simple short-circuiting of 'definite ham' or 'definite spam' messages based on individual short-circuit rules using the 'shortcircuit' setting, by Dallas Engelken <dallase /at/ nmgi.com>
bug 4603: Mail::SpamAssassin::Spamd::Apache2 – mod_perl2 module, implementing spamd as a mod_perl module, contributed as a Google Summer of Code project by Radoslaw Zielinski
decided to add a public function to set the rendered information instead of expecting plugins to nastily muck with our internal data... bad juju.
bug 5127: allow mimeheader :raw rules to match newlines and folded-header whitespace in MIME header strings
Move rule functionality and checking into separate Check plugin.
bug 3991: spamd can now listen on UNIX domain, TCP, and SSL sockets simultaneously. Command-line semantics extended slightly, although fully backwards compatibly; add the --ssl-port switch to allow TCP and SSL listening at the same time
reduce memory footprint by about 750KB by: deleting the source for compiled rulesets; deleting stuff used to parse config; compacting the descriptions hash into a single string, for more RAM -efficient but slower lookups
DomainKeys/DKIM stuffs
ArchiveIterator/mass-check cleanups
sa-compile stuffs
bug 5206: detect duplicate rules, and silently merge them internally for greater efficiency. This results in about 100-120KB RAM usage saving in current svn trunk's ruleset, detecting lots of duplicate rules – so is well worth doing. also, change t/priorities.t so it doesn't accidentally confuse itself with duplicate rules
Break out of EvalTests into various plugins.
bug 5236: Support Mail::SPF replacement for Mail::SPF::Query
bug 5243: add Plugin::register_method_priority() API, allowing plugins to control the relative ordering of plugin callbacks relative to other plugins' implementations
bug 3466: do the bayes expiry after results have been passed back to the client from spamd, helps avoid client timeouts, etc.
mass-check client/server mode
Removed Text::Wrap dependency
add spamc '-z' switch, which compresses mails to be scanned using zlib compression; very useful for long-distance use of spamc over the internet.
bug 4770: add ASN.pm plugin, contributed by Matthias Leisi <matthias at leisi.net>
bug 5296: add spamc --headers switch, which scans messages and transmits back just rewritten headers. This is more bandwidth-efficient than the normal mode of scanning, but only works for 'report_safe 0'. Bump spamc/spamd's protocol version to 1.4, to reflect new HEADERS verb.
bug 5305: implement msa_networks for detecting MSAs and extending trust accordingly
bug 4271: move ImageInfo into 3.2.0 core ruleset
VBounce Plugin
