Beta 2 has been released! This version adds some new functionality and corrects several issues found in v2.1.0 Beta 1 and older versions of SWFUpload.

The demos and documentation have been updated as well.

Changes: (changelog.txt)

New Features
- Added addPostParam and removePostParam functions that allow add/removing post params without having to send the entire post params object.
- Added requeue_on_error setting that allows you to "try again" if an upload fails. This feature can conflict with the Queue Plugin. Read the docs.
- New SWFObject plugin which improves Flash Version detection and embedding. Also adds a "load failed" event and Dom Ready functionality. This plugin replaces the Graceful Degradation plugin, DomReady plugin and Flash Detection Kit plugin.
- Added Demos for SWFObject plugin, CookieBug and a VB.Net version of the Application Demo.

Bug Fixes
- Fixed & not being removed from post params
- Fixed file param debug output showing 'undefined'
- Added workaround for file param names triggering a Flash Player bug.
- Fixed upload_url_missing error state so it is detected more reliably
- Fixed file params not being sent when useQueryString is used
- Changed the internal behavior of HTTP errors and IO errors

Not Fixed
- Mac OS issue with 302 redirects and subdomains are Flash Player bugs. It looks like this also affects the Linux Flash Player.
- Missing button text in the File Dialog in OS X is a Flash Player bug.
- Empty post params are not sent with the upload. This is a Flash Player plug.
