Clarion 7 Release Notes

The last release for Clarion 7 was in April 2011. See below for the various release notes that I can still find. There are quite a few missing. If you happen to have any copies lying around please contribute. These list can be very helpful for finding reasons for changes in behaviour when upgrading applications from one version to the next. Not to mention the historical interest!
