I just released version 0.2.2 of ZipStream-PHP. ZipStream-PHP is a library that allows you to generate and stream zip files on the fly without writing an intermediate temporary file to the disk. It works with existing files and dynamically generated content, and has been used to dynamically generate zip files hundreds of megabytes in size.
This release of ZipStream-PHP updates the license to remove the advertising clause and fixes a few errors in the documentation. There are no code changes; if you're happy with 0.2.1 there is no immediate reason to upgrade.
