9.7.1.0.30 Release Notes are linked to the download page. See section 5.1.34. Resolved Issues in MR Refresh (post MR build 9.7.1.0.17)
9.8 will be a "new feature" GA release.
9.7.1.0.30 corrects a number of issues seen since the release of the .17 release, and we felt a couple were important enough to warrant a refresh rather than waiting for the next MR which is still a few weeks out.
