'''Changed behavior'''

The Windows reigstry key/value which holds the root installation
directory for Tcl/Tk changed (again!).  To retrieve that directory
from the Windows registry, use the Tcl command

 registry get HKEY_LOCAL_MACHINE\\SOFTWARE\\Scriptics\\Tcl\\[info tclversion] Root

Advanced regular expressions.  See regexp(n).  The changes result
in incompatibilities at the C API as well as potential incompatibilities
in regular expressions.

Expanded ''scan'' functionality, including XPG3.  See scan(n).

\ooo, \xhh, and \uhhhh escapes indicate Unicode character values.

''format %c'' converts to Unicode; no longer limited to 8 bits.

'''New C-API's'''

''Tcl_SaveResult'',
''Tcl_RestoreResult'',
''Tcl_DiscardResult''.
Use these if you have to use the interpreter result for communication with a Tcl script (f.e. called from the C-level), but don't want to trash the current result as your caller might rely on it.
