We have uploaded a new release for AZARDI (2009-06-02). This is a minor feature change release.
When using edit mode, this release saves the content files in the zip package as deflate rather than store by default (except the mimetype file which is always stored). This has the dual benefit of reducing the ePub file size and overcoming a minor bug in the Sony devices that expects zips to be deflate compressed and therefore miscalculates resource.
Download AZARDI 2-2 from here.
Source code will be available on the Version History page in approximately seven days.
