+title:  "Schleuder 3.3.0 released!"
+date: "2018-09-04"
+---
+
+This release contains a few bug fixes and improvements: Missing arguments to keywords are now properly handled, and also more helpful error messages are provided; "Protected Headers" now are handled in a way that Thunderbird/Enigmail recognize; we also introduced a new keyword to remove a fingerprint from a subscription, and protected X-SET-FINGERPRINT better against accidental mis-use.
+
+Additionally the pseudoheaders now fully depend on the 'headers_to_meta' configuration-option, including 'sig' and 'enc'; in effect you can now also have a fully empty pseudoheaders-block, which might come in handy for newsletters. Thanks to all contributors! Packages for Debian and CentOS will be released soon. For all details please see the [changelog](https://0xacab.org/schleuder/schleuder/blob/master/CHANGELOG.md#330-2018-09-04).

+This release ships an important privacy fix: To not leak keywords (for example via resent messages), HTML is now stripped from multipart/alternative messages if they contain keywords.

+
+Since Schleuder 3.3.0 it is possible to extend the schleuder filters through externally provided filters. A project that is using this mechanism is the [schleuder-gitlab-ticketing]({{"/schleuder-gitlab-ticketing" | absolute_url}}) project, that provides tracking functionality of your schleuder messaging within a gitlab issue tracker. This is especially built and helpful for schleuder lists being used as helpdesk or project gateway. Read more about the functionality on the projects summary page: [schleuder-gitlab-ticketing]({{"/schleuder-gitlab-ticketing" | absolute_url}}).

+
+This release fixes two problems with the handling of emails containing “protected headers”, and it drops third-party signatures on OpenPGP keys when importing to prevent signature flooding (if your version of GnuPG is recent enough).
