I recently released Version 0.8 of TclRAL and thought that now was an appropriate time to make this page a bit more active for anyone that may be interested in the extension and wish to ask questions or post examples.
Version 0.8 is a complete rewrite of the extension to improve the code base and lay in a more maintainable structure. The major new feature of 0.8 is referential integrity checking. My current vision for the future is (roughly):
I won't be so bold as to state a time frame for all of this, but as I use the extension myself I am as anxious to see it improve as anyone.

Released Version 0.8.1. This version is script compatible with 0.8 and includes some new commands and command options. Most notable is the ability to trace relvars in much the same manner that one can trace ordinary Tcl variables.
