Sender and Receiver interoperability
RGS provides interoperability between versions of RGS Senders and Receivers that have the same
primary version number. A connection between a Receiver and a Sender should only be attempted
when their primary version numbers are the same.
See below for a description of the RGS version number components.
Figure 2-2 RGS version numbering
1. Primary version number—A primary release contains sufficient changes such that
interoperability with the prior primary release is not guaranteed. For example, Sender version 5.4
is not guaranteed to interoperate with Receiver version 6.0. A major release introduces
significant new RGS features and functionality. They will also include (roll up) the changes in any
prior minor and patch releases.
2. Minor version number—Minor releases introduce new RGS features and functionality. Minor
releases will also include (roll up) the changes in any prior patch releases. RGS 5.4.0 is a minor
release.
3. Patch version number—Patch releases are generated only for a security issue or for a major
defect in a feature. A patch release is indicated by this number being non-zero. Therefore, RGS
5.4.0 would not be a patch release. RGS 5.4.1 would be a patch release.
NOTE: Each patch release is a complete release of the entire RGS product, regardless of what
components have changed. For example, if a patch release is needed to make an RGS Sender
security fix available, the entire RGS product (including both the RGS Sender and Receiver) would be
included in the patch release.
