Orbisius Release Manager allows WordPress developers/designers to easily release their plugins (soon and themes) at WordPress.org

The tool simplifies the job of the WordPress developer by allowing him/her to release a version using a single click.
The tools will tell you if a plugin needs to be tested with the latest WordPress version (by checking the readme file).

Also it warns you if there are any uncommited changes, the stable tag doesn't match the current version etc.
It also checks if you have a change log for a given version and much more.

When all conditions are met the Push Release button will appear.
Shows the release directory in a nice textbox for easy copy/paste.Note: The tool is intended to be used on the local development machine that's not accessible from the internet.
