The best way to get this type of information is to look at the
tnm/changes file. All changes that introduce incompatibilities should
be marked with the string "*** POTENTIAL INCOMPATIBILITY ***".
However, some changes don't make it into the changes file (especially
the one you are talking about) and sometimes it is not obvious if a
bug fix introduces an incompatibility because the exact behavior was
never defined before. A couple of changes on the way from 2.0.* to
2.1.* fall into this category since the documentation was often not
clear about what exactly a command will do. I hope this improved in
2.1.* but there are still some things that are not well documented.
If you find such problems, please let me know.
For example, I recently changed the scope of default options like
'icmp -timeout 3'. Previous versions assumed a global scope while the
current version limits the scope to the current Tcl interpreter. This
avoids side-effects if you write scripts that use multiple Tcl
interpreters. Changes like this are sometimes not marked because the
behavior has never been defined before and I don't expect that many
scripts will be affected by such a change.
