…er (GH-153514) FromObj() now returns str for the "index", "window", "nsName" and "parsedVarName" object types, whose internal representation is only a context-bound lookup with nothing worth preserving in a Tcl_Obj. An "index" value is one of a small fixed set of enumeration keywords, so its str is interned. A "pixel" screen distance with no unit suffix is screen independent and is now returned as an int or float. A distance with an m/c/i/p suffix needs a Tk_Window to be resolved and is kept as a Tcl_Obj, as are the "dict" and the resource types "color", "border", "font" and "cursor".

…-153495) IMAP4.search(), sort(), thread() and the uid SORT/THREAD variants now encode str search criteria to the declared charset, so international search text can be passed as ordinary str. A criterion passed as bytes is sent unchanged, for use with a charset that Python has no codec for. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Now that index, window, parsedVarName and pixel options are returned as str, int or float, drop the str()/int()/float() wrappers that only worked around Tcl_Obj results. The generated test_configure_* tests now also check that int- and float-valued options are returned as numbers. Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
…widget names (GH-151975) The "!" prefix has a special meaning in the tag expressions of the canvas and text widgets ("!", "&&", "||", "^" and parentheses), so an automatically generated widget name could not be used as a tag. "+" has no special meaning there, nor in option database patterns or Tcl lists, and a user is very unlikely to start an explicit name with it.
…ken (GH-152310) The _tkinter.tkapp and _tkinter.tktimertoken types never implemented the garbage collector protocol, so reference cycles through an interpreter's trace function or a timer handler's callback could not be collected. A pending timer is kept alive by the Tcl event loop, which fires it even after the Python token is dropped, so it is treated as a GC root (only its callback is traversed) and collecting it never cancels a live timer. The GC slots use a plain cast rather than the type-checking macro, since the collector may visit a surviving object at shutdown after module clearing has reset the global type pointers. Deallocation cancels any pending timer so its callback cannot run on freed memory.

ScrolledText gained a keyword-only use_ttk parameter to build the surrounding frame and the vertical scroll bar from the themed tkinter.ttk widgets instead of the classic tkinter widgets. The classic widgets remain the default. Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
