Version Policies What is a New Release? A new release is simply the full installation of an Aspose product. The install file includes all necessary files: including the product executable file (ex: Aspose.Cells.dll), help files and demos files. Version Number for a New Release The version number for a new release looks like x.y.0.0: y means yth release. For example, 1.5.0.0 means 5th release. If y is greater than 9, then x will be added to x + 1 and y becomes 0. For example, after release 1.9.0.0, the new release will be 2.0.0.0. What is a Hot Fix? After a new release of a product is published at Downloads, from time-to-time our development teams may publish a hot fix to address bug reports or feature requests by certain customers at Aspose Forums . The hot fix is a zip file which only includes the product's executable file (ex: Aspose.Cels.dll). Version Number for a Hot Fix The version number for a hot fix looks like x.y.z.0: z means the zth fix after a new release x.y. For example, 1.5.1.0 means 1st hot fix of the new release 1.5.0.0.
