Asset Packager Updates

Some updates to Asset Packager

• asset_packager now tolerates periods in asset names. (Ex: “admin.base.css”) Thanks Timur Vafin.

• updated Capistrano integration docs

• before the compressed assets were getting the subversion revision for the entire repository. Now they get the last modified revision possible for each file. Now it should work as intended – no revision stamp change unless the source files have been updated!
