On behalf of the Apache SpamAssassin Project, I am pleased to announce version 3.4.5 is available.
Release Notes -- Apache SpamAssassin -- Version 3.4.5
Apache SpamAssassin 3.4.5 is primarily a security release.
In this release, there are bug fixes for one CVE.
*** On March 1, 2020, we stopped publishing rulesets with SHA-1 signatures.
If you do not update to 3.4.2 or later, you will be stuck at the last
ruleset with SHA-1 signatures. Such an upgrade should be to 3.4.5 to
obtain the contained security fixes ***
*** Ongoing development on the 3.4 branch has ceased. All future releases
and bug fixes will be on the 4.0 series, unless a new security issue
is found that necessitates a 3.4.6 release. ***
Many thanks to the committers, contributors, rule testers, mass checkers,
and code testers who have made this release possible.
In addition to the CVE which shall be announced separately, this release
includes fixes for the following:
- Improvements to OLEVBMacro and AskDNS plugins
- Received and EnvelopeFrom headers matching improvements
- userpref SQL schema fixes
- rbl and hashbl evaluation improvements
- fix for non working TxRep tag names
- man page fixes
