Daniel Jalkut has announced the beta for MarsEdit 4:
It’s been over 7 years since MarsEdit 3 was released. Typically I would like to maintain a schedule of releasing major upgrades every two to three years. This time, a variety of unexpected challenges led to a longer and longer delay.
The good news? MarsEdit 4 is finally shaping up. I plan to release the update later this year.
I’ve used MarsEdit for quite a while and I used to use it to publish to my original Chorus.fm Tumblr blog. Once I moved to WordPress for Chorus, I’d made so many minor tweaks to the system and my workflow that it didn’t quite do all I needed to anymore. However, this update looks like it’ll be adding in a bunch of features that may let me use it again for posting. That’d be exciting.
