Hi,

I've noticed that between RHEL minor releases, packages are sometimes upgraded to new major upstream versions (as opposed to upstream maintenance releases / updates). However, these upgrades are not always being documented in either the technical notes or the release notes.

For example, xorg-x11-xserver (X.org Server) has been upgraded 3 times in RHEL 6.x minor releases:
1.7 (6.0) -> 1.10 (6.2) -> 1.13 (6.5) -> 1.15 (6.6)

While I greatly appreciate new hardware enablement and new features in X.org Server, I would expect to see these major version upgrades reflected in either the release notes or the technical notes.

The 1.10 upgrade was documented:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/6.2_Release_Notes/graphics.html

But the 1.13 upgrade was not. It might be implied from the Release Notes that it was upgraded:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/6.5_Release_Notes/bh-chap-desktop_and_graphics.html
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/6.5_Technical_Notes/xorg-x11-server.html

And there is no sign of the 1.15 upgrade in the documentation:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/6.6_Release_Notes/bh-chap-desktop_and_graphics.html
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/6.6_Technical_Notes/index.html

My interest in this is two-fold.
1. In my free time, I contribute to the X2Go project, which is maintaining a fork of X.org called nx-libs. If a Linux distro is upgrading the X.org server, we want to know about it, because applications may assume that the linux distro's users have a much newer version of X.org server than nx-libs is based on.
2. At work, we may migrate to RHEL. When a package is upgraded to a new major version, we would presumably want to do extra regression testing of our code that uses that package.

Thanks,
