Releases
Here's a list of recent releases of Closure Compiler. See the README for how to obtain the latest release. We also update the source distribution and the compile service (at http://closure-compiler.appspot.com) at each release. The Closure Compiler team's goal is to release during the first week of every month, although we may miss that deadline due to unexpected internal test failures or holidays
