 -- Issue #22115: Fixed tracing Tkinter variables: trace_vdelete() with wrong
 -  mode no longer break tracing, trace_vinfo() now always returns a list of
 -  pairs of strings, tracing in the "u" mode now works.
 +- Issue #22115: Added methods trace_add, trace_remove and trace_info in the
 +  tkinter.Variable class.  They replace old methods trace_variable, trace,
 +  trace_vdelete and trace_vinfo that use obsolete Tcl commands and might
-   not work in future versions of Tcl.
++  not work in future versions of Tcl.  Fixed old tracing methods:
++  trace_vdelete() with wrong mode no longer break tracing, trace_vinfo() now
++  always returns a list of pairs of strings, tracing in the "u" mode now works.

 +- Issue #26243: Only the level argument to zlib.compress() is keyword argument
 +  now.  The first argument is positional-only.
  
 -- Fix a scoping issue in importlib.util.LazyLoader which triggered an
 -  UnboundLocalError when lazy-loading a module that was already put into
 -  sys.modules.
 +- Issue #27038: Expose the DirEntry type as os.DirEntry. Code patch by
 +  Jelle Zijlstra.
 +
 +- Issue #27186: Update os.fspath()/PyOS_FSPath() to check the return value of
 +  __fspath__() to be either str or bytes.
 +
 +- Issue #18726: All optional parameters of the dump(), dumps(),
 +  load() and loads() functions and JSONEncoder and JSONDecoder class
 +  constructors in the json module are now keyword-only.
 +
 +- Issue #27319: Methods selection_set(), selection_add(), selection_remove()
 +  and selection_toggle() of ttk.TreeView now allow passing multiple items as
 +  multiple arguments instead of passing them as a tuple.  Deprecated
 +  undocumented ability of calling the selection() method with arguments.
  
  - Issue #27079: Fixed curses.ascii functions isblank(), iscntrl() and ispunct().
