There's been a huge amount of working going in to SWF Tools recently, and people are starting to try out the new 6.x-3.x code.
The code is largely settled now, so I'm making this beta release to create a standard reference point.
Please read the upgrade notes at #745050: Create upgrade instructions for 6.x-2.x to 6.x-3.x before using this package. The upgrade path is a little bit different to normal as a result of fixing a namespace collision with another module.
Also note that unlike most SWF Tools update you do have to run update.php
this time round as the way some settings are stored has altered, and there are some new theme functions to be registered.
I'm not going to put the list of fixes and updates in here - check CHANGELOG.txt for details. I've tried to record the change liberally.
Key features are enhanced CCK support (including text fields, link fields, and thumbnails). CCK descriptions will now be used if you have them. getID3 integration lets you pick up tags. Support for WordPress audio is in (the "new" OnePixelOut player). Wijering4, FlowPlayer3 and WordPress audio all have the option to be made accessible by placing hyperlinks on the page, and all three have auto-pause behavior (with other players of the same type) so if you have multiple players then starting a second will pause the first.
