+        <description>ImageProcessor.Web adds a configurable HttpModule to your website which allows on-the-fly processing of image files. The module also comes with a file and browser based cache that can handle up to 12,960,000 images increasing your processing output and saving precious server memory.
+
+Methods include; Resize, Rotate, Flip, Crop, Watermark, Filter, Saturation, Brightness, Contrast, Quality, Format, Vignette, and Transparency.
+
+This package also requires Microsoft.Bcl.Async -pre on .NET 4.0 which will be added in the background on install if applicable.

+
+If upgrading from &lt; 2.2.0.0 You will have to delete your cache if upgrading to this version as the database differs.</releaseNotes>
