When JShrink was first created it was meant to solve a simple problem- minify javascript as quickly as possible, and do so with an open source license.
JShrink has been in development for several years now. It's migrated from Google Code to Github and modernized with support for things like Composer and the PSR standards. It's been adopted by numerous projects (SugarCRM and Piwik are two examples), and extended by other developers for use with Assetic and Symfony2. Through Packagist along it has had over 32k downloads (over 5k of which was just last month). In recent months a lot of work has been put into increasing test coverage, adopting standards, and making contributions easier. This latest version of JShrink is the fastest, best documented, and most comprehensively tested version yet.
All of which leads to this, JShrink 1.0.
Thank you to everyone who has contributed to and adopted JShrink!
