Version 6.8.5 has been release yesterday with a fix on subscription form minimal type. The fix is about the alternative confirmation URL, something very specialized. The update, with our previous release, grants full compatibility with WordPress 5.5 and give support to the new Reports Addon.
The Reports Addon now adds a new targeting option: the subscription date.
If you already have the Report Addon, simply update it from your blog plugin management page. Of course it requires the latest version of Newsletter. We recommend to always keep it updated.
