'''Changed behavior'''

The Windows registry 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.

'''AK'''
