WordPress 2.5 Compatible!
All the emails finally wore me down and I spent the last two days making the Newsletter Plugin compatible with WordPress 2.5. I was going to make you all wait until Newsletter v3.0 was ready for WP 2.5 compatibility, but it’s just not coming fast enough for you folks!
Anyway, please note that the new WP Newsletter 2.2.7 is still compatible with older versions of WordPress. The biggest change to this 2.5 compatible version was the Text editor and media uploads, and in 2.5 you can only use TinyMCE or QuickTags for your Content. Any additional sideboxes or metaboxes are unable to use the Rich Text editor and will need to be written in HTML only for now.
