Even though Flash 8 has been released, many people haven't updated their Flash Players yet. This means that if they watch your Flash 8 work with filters and new ActionScript, etc. it won't show up. You could make a great movie/game with all these great effects, but they won't show up which could result in a low score. Even worse, you could have a game that uses new Flash 8 ActionScript, but the viewer doesn't have the new Flash Player, so they can't play it properly and they may think it sucks while it's actually an amazing game!!
I have made a Flash-Checking Component to put in your flash to make sure the user has the newest Flash Player.
Here's a preview of how it works:

Here's the downloadable FLA file with the component:
Flash-Checker Component
To use this component, simply Copy/Paste it into the first frame of your Flash files.
This component can work with any Flash Player version (so you could use this in the future with something like Flash 14). You simply open the Actions Panel for the Component on the stage and change the string "8" to whatever version you want to check for. So if you want version 14, you'd change "8" to "14". Just don't try to change it to a lower version like 7 or 6, because people with version 8 won't be able to downgrade to those making them never be able to view the Flash.
You may use this in any Flash stuff you want to, I designed this to help people with not having to wait for people to update their Flash Players, etc.
I hope this helps you out!!
