Ranchero Software this weekend released MarsEdit 1.0, a new weblog editor for Mac OS X.

The product makes weblog writing like writing email. Posts can be edited alone, saved as drafts and spell-checked. Additional features include support for categories, text filters, trackbacks, custom templates and AppleScript support. Image and file uploading tools also feature in the release.

MarsEdit works with Movable Type, TypePad, Radio UserLand, WordPress, Blosxom, and many other blogging engines.

MarsEdit is available for download. It costs $24.95 for a single-user license. Multi-user licensing costs $19.95 per user, for two or more users.
