Xbuf2 is the intended future replacement of Xbuf. It is presented in the current version as a separate encoding type only because the API of the generated Xbuf2 classes have some minor compatibilities with the Xbuf generated classes (see below). Therefore, Xbuf2 is being offered as a separate encoding type in the current version. The next major Talon version will only contain the Xbuf encoding type which will be the current Xbuf2 encoding renamed to Xbuf. Talon applications that currently use the Xbuf encoding type, particularly those that use the Xbuf API methods not supported by Xbuf2 are strongly encouraged to move to Xbuf2 to ease the migration to the next major version of Talon.
