New Features for Flash Player 21:
When a Context3D object is created, developers allocate memory for various Stage3D structures which include index buffers, vertex buffers, textures, and programs. Prior to Flash and AIR 21, the only way to verify the memory allocated by the current Context3D is through values displayed by Scout. With the release of Flash Player and AIR 21, a new property of context3D class called "totalGPUMemory" has been introduced which provides the sum of gpu memory used by the index buffers, vertex buffers, textures, and programs created through Context3D.
The total value can be obtained by property "Context3D.totalGPUMemory;".
The value of this property is in bytes and its default value is 0. The information is only provided in direct mode on mobile and in direct and GPU mode on desktop ( On desktop computers, using <renderMode>gpu</renderMode> will fallback to <renderMode>direct</renderMode>). This property can be used when the SWF version is 32 or more .
We’ve extended the support for Browser Zoom Feature that proposes scaling of Flash content in the web browser in response to web page zoom factor change. The feature is already available for the ActiveX and PPAPI plugin (link).
It will be available from FP version 21 and is currently available on Firefox Nightly 45.0a1, the official Firefox version supporting the feature has yet to be announced.
As of Flash Player version 19, Vector Printing has only been available for NPAPI while PPAPI supported only bitmap printing. Hence there was an observable difference in printing quality between NPAPI and PPAPI (with NPAPI being better). Now in version 21, we have introduced vector printing for PPAPI for OSX, thus giving a better printing experience from PPAPI supported browsers and applications. The bitmap printing functionality will continue to be supported and used when requested by the content.
Flash player provides an per domain/swf option to store locally shared objects on user's system. In the past, users could specify the size up to which a domain or SWF could save their LSOs on their machine. We have now simplified the LSO UI Options. This Simple LSO feature will change the permission scheme and related dialogs to only allow/deny and universally imposes a rational upper limit to the LSO size. End users will no longer be able to specify the size of LSOs (but will be able to approve if LSOs can be created or not).
