2017-10-24: Schleuder 3.2.1 released! This release adds an explicit dependency on ruby-gpgme >= 2.0.13, which includes a fix for a bug people have run into. Please see the changelog of schleuder for details.

2017-10-23: Schleuder 3.2 released! This release adds two new features: An internal footer to be appended to each mail sent to a subcribed address, and an option to use an OS-wide defined keyserver (useful on Debian 9). On top, two new keywords: X-RESEND-UNENCRYPTED and X-RESEND-CC-UNENCRYPTED will send out mails in the clear, regardless of whether relevant keys exist. Additionally, some bugs were fixed. Don’t forget to run schleuder install after the update to apply a necessary database migration. Please see the changelog of schleuder for details.
