Product Versions
Developer Express Inc releases two major versions of .NET products a year, with a few minor releases in between. The full version notation includes three numbers that specify the year, major version and minor version of the release.
For example, “v18.2.7” (which is equivalent to “v2018 vol 2.7”) denotes the year 2018, 2nd major release, 7th minor update.
The version number can also be specified in a short form (for example, “v18.2” or “v2018 vol 2”) if the minor update number is not important.
