In prior versions of Flash “Deprecated” has encouraged developers to stop using certain methods and properties as future players may not support them. That said, many continue to be supported due to legacy of SWF content. Flash 8 player contains the first case where deprecated means not supported!&
In Flash 8, the “add” operator is no longer supported. This operator was deprecated in Flash 5, but existed until the release of Flash 8. As it is no longer supported in the Player, this may affect a very very small number of SWF files. I am not sure whether this is still available for legacy content with FP 7- headers but if you publish for Flash 8, “add” will not concatenate strings.
Not that this is a big loss, but I recall the Flash 4 days when I used “add” extensively. When “+” came along for string support I never looked back.
The lesson here is that deprecated has real meaning now and future players may well choose remove deprecated functionality for performance purposes. When you are writing content, watch the use of deprecated features. Plus not using these should be common sense by now.
