Silverlight is one of the popular plug-in developed by Microsoft. Silverlight works as a powerful development tool which will let you create interactive Web and Mobile application. Silverlight does also enhance your internet experience with support for video and other types of multimedia support. Microsoft has released the latest version of Silverlight 5 at 9th Dec. This 7 MB executable file supports both Windows and Mac as well as major Internet Browsers too. More to read.
About this update Microsoft has published a blog post. Features of Silverlight 5 are quoted from there:
New features in Silverlight 5 include Hardware Decode of H.264 media, which provides a significant performance improvement with decoding of unprotected content using the GPU; Postscript Vector Printing to improve output quality and file size; and an improved graphics stack with 3D support that uses the XNA API on the Windows platform to gain low-level access to the GPU for drawing vertex shaders and low-level 3D primitives.
In addition, Silverlight 5 extends the ‘Trusted Application’ model to the browser for the first time. These features, when enabled via a group policy registry key and an application certificate, mean users won’t need to leave the browser to perform complex tasks such as multiple window support, full trust support in browser including COM and file system access, in browser HTML hosting within Silverlight, and P/Invoke support for existing native code to be run directly from Silverlight.
So that’s all about Silverlight 5. Microsoft haven’t said anything about the next version while you might heard of a rumor like there will be no Silverlight 6. No comment about that while Microsoft says that they will support Silverlight 5 till November 12, 2021.
