-other uses of tokenize data and methods.
-
-gh-104499: Fix completions for Tk Aqua 8.7 (currently blank).
-
-gh-104486: Make About print both tcl and tk versions if different,
-as is expected someday.

-
-What's New in IDLE 3.11.0
-(since 3.10.0)
-Released on 2022-10-24
-=========================
-
-gh-97527: Fix a bug in the previous bugfix that caused IDLE to not
-start when run with 3.10.8, 3.12.0a1, and at least Microsoft Python
-3.10.2288.0 installed without the Lib/test package.  3.11.0 was never
-affected.
-
-gh-65802: Document handling of extensions in Save As dialogs.
-
-gh-95191: Include prompts when saving Shell (interactive input/output).
-
-gh-95511: Fix the Shell context menu copy-with-prompts bug of copying
-an extra line when one selects whole lines.
-
-gh-95471: Tweak Edit menu. Move 'Select All' above 'Cut' as it is used
-with 'Cut' and 'Copy' but not 'Paste'.  Add a separator between 'Replace'
-and 'Go to Line' to help IDLE issue triagers.
-
-gh-95411: Enable using IDLE's module browser with .pyw files.
-
-gh-89610: Add .pyi as a recognized extension for IDLE on macOS.  This allows
-opening stub files by double clicking on them in the Finder.
-
-bpo-28950: Apply IDLE syntax highlighting to `.pyi` files.  Add util.py
-for common components.  Patch by Alex Waygood and Terry Jan Reedy.
-
-bpo-46630: Make query dialogs on Windows start with a cursor in the
-entry box.
-
-bpo-46591: Make the IDLE doc URL on the About IDLE dialog clickable.
-
-bpo-45296: Clarify close, quit, and exit in IDLE.  In the File menu,
-'Close' and 'Exit' are now 'Close Window' (the current one) and 'Exit'
-is now 'Exit IDLE' (by closing all windows).  In Shell, 'quit()' and
-'exit()' mean 'close Shell'.  If there are no other windows,
-this also exits IDLE.
-
-bpo-45495: Add context keywords 'case' and 'match' to completions list.
-
-bpo-45296: On Windows, change exit/quit message to suggest Ctrl-D, which
-works, instead of <Ctrl-Z Return>, which does not work in IDLE.
-
-
-What's New in IDLE 3.10.0
-(since 3.9.0)
-Released on 2021-10-04
-=========================
-
-bpo-45193: Make completion boxes appear on Ubuntu again.
-
-bpo-40128: Mostly fix completions on macOS when not using tcl/tk 8.6.11
-(as with 3.9).
-
-bpo-33962: Move the indent space setting from the Font tab to the new Windows
-tab. Patch by Mark Roseman and Terry Jan Reedy.
-
-bpo-40468: Split the settings dialog General tab into Windows and Shell/Ed
-tabs. Move help sources, which extend the Help menu, to the Extensions tab.
-Make space for new options and shorten the dialog. The latter makes the
-dialog better fit small screens.
-
-bpo-44010: Highlight the new match statement's soft keywords: match, case,
-and _. This highlighting is not perfect and will be incorrect in some rare
-cases, especially for some _s in case patterns.
-
-bpo-44026: Include interpreter's typo fix suggestions in message line
-for NameErrors and AttributeErrors.  Patch by E. Paine.
-
-bpo-41611: Avoid occasional uncaught exceptions and freezing when using
-completions on macOS.
-
-bpo-37903: Add mouse actions to the shell sidebar.  Left click and
-optional drag selects one or more lines of text, as with the
-editor line number sidebar.  Right click after selecting text lines
-displays a context menu with 'copy with prompts'.  This zips together
-prompts from the sidebar with lines from the selected text.  This option
-also appears on the context menu for the text.
-
-bpo-43981: Fix reference leaks in test_sidebar and test_squeezer.
-Patches by Terry Jan Reedy and Pablo Galindo
-
-bpo-37892: Change Shell input indents from tabs to spaces.  Shell input
-now 'looks right'.  Making this feasible motivated the shell sidebar.

-masquerade rules or failure displaying complex colored (non-ascii) characters.
-
-bpo-43283: Document why printing to IDLE's Shell is often slower than
-printing to a system terminal and that it can be made faster by
-pre-formatting a single string before printing.
-
-bpo-23544: Disable Debug=>Stack Viewer when user code is running or
-Debugger is active, to prevent hang or crash.  Patch by Zackery Spytz.
-
-bpo-43008: Make IDLE invoke :func:`sys.excepthook` in normal,
-2-process mode.  User hooks were previously ignored.
-Patch by Ken Hilton.
-
-bpo-33065: Fix problem debugging user classes with __repr__ method.
-
-bpo-32631: Finish zzdummy example extension module: make menu entries
-work; add docstrings and tests with 100% coverage.
-
-bpo-42508: Keep IDLE running on macOS.  Remove obsolete workaround
-that prevented running files with shortcuts when using new universal2
-installers built on macOS 11.
-
-bpo-42426: Fix reporting offset of the RE error in searchengine.
-
-bpo-42416: Display docstrings in IDLE calltips in more cases,
-by using inspect.getdoc.
-
-bpo-33987: Mostly finish using ttk widgets, mainly for editor,
-settings, and searches.  Some patches by Mark Roseman.
-
-bpo-40511: Stop unnecessary "flashing" when typing opening and closing
-parentheses inside the parentheses of a function call.
-
-bpo-38439: Add a 256x256 pixel IDLE icon to the Windows .ico file. Created by
-Andrew Clover. Remove the low-color gif variations from the .ico file.
-
-bpo-41775: Make 'IDLE Shell' the shell title.
-
-bpo-35764: Rewrite the Calltips doc section.
-

-positional-only arguments.
-
-
-What's New in IDLE 3.9.0 (since 3.8.0)
-Released on 2020-10-05?
-======================================
-
-bpo-41468: Improve IDLE run crash error message (which users should
-never see).
-
-bpo-41373: Save files loaded with no line ending, as when blank, or
-different line endings, by setting its line ending to the system
-default. Fix regression in 3.8.4 and 3.9.0b4.
-
-bpo-41300: Save files with non-ascii chars.  Fix regression in
-3.9.0b4 and 3.8.4.
-
-bpo-37765: Add keywords to module name completion list.  Rewrite

-when fetching a calltip.
-
-bpo-27115: For 'Go to Line', use a Query entry box subclass with
-IDLE standard behavior and improved error checking.
-
-bpo-39885: When a context menu is invoked by right-clicking outside
-of a selection, clear the selection and move the cursor.  Cut and
-Copy require that the click be within the selection.
-
-bpo-39852: Edit "Go to line" now clears any selection, preventing
-accidental deletion.  It also updates Ln and Col on the status bar.
-
-bpo-39781: Selecting code context lines no longer causes a jump.
-
-bpo-39663: Add tests for pyparse find_good_parse_start().
-
-bpo-39600: Remove duplicate font names from configuration list.
-
-bpo-38792: Close a shell calltip if a :exc:`KeyboardInterrupt`
-or shell restart occurs.  Patch by Zackery Spytz.
-
-bpo-30780: Add remaining configdialog tests for buttons and
-highlights and keys tabs.
-
-bpo-39388: Settings dialog Cancel button cancels pending changes.

-
-bpo-38943: Fix autocomplete windows not always appearing on some
-systems.  Patch by Johnny Najera.

-
-bpo-38598: Do not try to compile IDLE shell or output windows.
-
-
-What's New in IDLE 3.8.0 (since 3.7.0)
-Released on 2019-10-14
-======================================
-
-bpo-36698: IDLE no longer fails when writing non-encodable characters
-to stderr.  It now escapes them with a backslash, like the regular
-Python interpreter.  Add an errors field to the standard streams.
-
-bpo-13153: Improve tkinter's handing of non-BMP (astral) unicode
-characters, such as 'rocket \U0001f680'.  Whether a proper glyph or
-replacement char is displayed depends on the OS and font.  For IDLE,
-astral chars in code interfere with editing.
-
-bpo-35379: When exiting IDLE, catch any AttributeError.  One happens
-when EditorWindow.close is called twice.  Printing a traceback, when
-IDLE is run from a terminal, is useless and annoying.
-
-bpo-38183: To avoid test issues, test_idle ignores the user config
-directory.  It no longer tries to create or access .idlerc or any files
-within.  Users must run IDLE to discover problems with saving settings.
-
-bpo-38077: IDLE no longer adds 'argv' to the user namespace when
-initializing it.  This bug only affected 3.7.4 and 3.8.0b2 to 3.8.0b4.
-
-bpo-38401: Shell restart lines now fill the window width, always start
-with '=', and avoid wrapping unnecessarily. The line will still wrap
-if the included file name is long relative to the width.
-
-bpo-37092: Add mousewheel scrolling for IDLE module, path, and stack
-browsers.  Patch by George Zhang.
-
-bpo-35771: To avoid occasional spurious test_idle failures on slower
-machines, increase the ``hover_delay`` in test_tooltip.
-
-bpo-37824: Properly handle user input warnings in IDLE shell.
-Cease turning SyntaxWarnings into SyntaxErrors.
-
-bpo-37929: IDLE Settings dialog now closes properly when there is no
-shell window.
-
-bpo-37849: Fix completions list appearing too high or low when shown
-above the current line.
-
-bpo-36419: Refactor autocompete and improve testing.
-
-bpo-37748: Reorder the Run menu.  Put the most common choice,
-Run Module, at the top.
-
-bpo-37692: Improve highlight config sample with example shell
-interaction and better labels for shell elements.
-
-bpo-37628: Settings dialog no longer expands with font size.
-The font and highlight sample boxes gain scrollbars instead.
-
-bpo-17535: Add optional line numbers for IDLE editor windows.
-
-bpo-37627: Initialize the Customize Run dialog with the command line
-arguments most recently entered before.  The user can optionally edit
-before submitting them.
-
-bpo-33610: Code context always shows the correct context when toggled on.
-
-bpo-36390: Gather Format menu functions into format.py.  Combine
-paragraph.py, rstrip.py, and format methods from editor.py.
-
-bpo-37530: Optimize code context to reduce unneeded background activity.
-Font and highlight changes now occur along with text changes instead
-of after a random delay.
-
-bpo-27452: Cleanup config.py by inlining RemoveFile and simplifying
-the handling of __file__ in CreateConfigHandlers/
-
-bpo-26806: To compensate for stack frames added by IDLE and avoid
-possible problems with low recursion limits, add 30 to limits in the
-user code execution process.  Subtract 30 when reporting recursion
-limits to make this addition mostly transparent.
-
-bpo-37325: Fix tab focus traversal order for help source and custom
-run dialogs.
-
-bpo-37321: Both subprocess connection error messages now refer to
-the 'Startup failure' section of the IDLE doc.
-
-bpo-37177: Properly attach search dialogs to their main window so
-that they behave like other dialogs and do not get hidden behind
-their main window.
-
-bpo-37039: Adjust "Zoom Height" to individual screens by momentarily
-maximizing the window on first use with a particular screen.  Changing
-screen settings may invalidate the saved height.  While a window is
-maximized, "Zoom Height" has no effect.
-
-bpo-35763: Make calltip reminder about '/' meaning positional-only less
-obtrusive by only adding it when there is room on the first line.
-
-bpo-5680: Add 'Run Customized' to the Run menu to run a module with
-customized settings. Any command line arguments entered are added
-to sys.argv. One can suppress the normal Shell main module restart.
-
-bpo-35610: Replace now redundant editor.context_use_ps1 with
-.prompt_last_line.  This finishes change started in bpo-31858.
-
-bpo-32411: Stop sorting dict created with desired line order.
-
-bpo-37038: Make idlelib.run runnable; add test clause.
-
-bpo-36958: Print any argument other than None or int passed to
-SystemExit or sys.exit().
-
-bpo-36807: When saving a file, call file.flush() and os.fsync()
-so bits are flushed to e.g. a USB drive.
-
-bpo-36429: Fix starting IDLE with pyshell.
-Add idlelib.pyshell alias at top; remove pyshell alias at bottom.
-Remove obsolete __name__=='__main__' command.
-
-bpo-30348: Increase test coverage of idlelib.autocomplete by 30%.
-Patch by Louie Lu.
-
-bpo-23205: Add tests and refactor grep's findfiles.
-
-bpo-36405: Use dict unpacking in idlelib.
-
-bpo-36396: Remove fgBg param of idlelib.config.GetHighlight().
-This param was only used twice and changed the return type.
-
-bpo-23216: IDLE: Add docstrings to search modules.
-
-bpo-36176: Fix IDLE autocomplete & calltip popup colors.
-Prevent conflicts with Linux dark themes
-(and slightly darken calltip background).
-
-bpo-36152: Remove colorizer.ColorDelegator.close_when_done and the
-corresponding argument of .close().  In IDLE, both have always been
-None or False since 2007.
-
-bpo-36096: Make colorizer state variables instance-only.
-
-bpo-32129: Avoid blurry IDLE application icon on macOS with Tk 8.6.
-Patch by Kevin Walzer.
-
-bpo-24310: Document settings dialog font tab sample.
-
-bpo-35689: Add docstrings and tests for colorizer.
-
-bpo-35833: Revise IDLE doc for control codes sent to Shell.
-Add a code example block.
-
-bpo-35770: IDLE macosx deletes Options => Configure IDLE.
-It previously deleted Window => Zoom Height by mistake.
-(Zoom Height is now on the Options menu).  On Mac, the settings
-dialog is accessed via Preferences on the IDLE menu.
-
-bpo-35769: Change new file name from 'Untitled' to 'untitled'.
-
-bpo-35660: Fix imports in window module.
-
-bpo-35641: Properly format calltip for function without docstring.
-
-bpo-33987: Use ttk Frame for ttk widgets.
-
-bpo-34055: Fix erroneous 'smart' indents and newlines in IDLE Shell.
-
-bpo-28097: Add Previous/Next History entries to Shell menu.
-
-bpo-35591: Find Selection now works when selection not found.
-
-bpo-35598: Update config_key: use PEP 8 names and ttk widgets,
-make some objects global, and add tests.
-
-bpo-35196: Speed up squeezer line counting.
-
-bpo-35208: Squeezer now counts wrapped lines before newlines.
-
-bpo-35555: Gray out Code Context menu entry when it's not applicable.
-
-bpo-22703: Improve the Code Context and Zoom Height menu labels.
-The Code Context menu label now toggles between Show/Hide Code Context.
-The Zoom Height menu now toggles between Zoom/Restore Height.
-Zoom Height has moved from the Window menu to the Options menu.
-
-bpo-35521: Document the editor code context feature.
-Add some internal references within the IDLE doc.
-
-bpo-34864: When starting IDLE on MacOS, warn if the system setting
-"Prefer tabs when opening documents" is "Always".  As previous
-documented for this issue, running IDLE with this setting causes
-problems.  If the setting is changed while IDLE is running,
-there will be no warning until IDLE is restarted.
-
-bpo-35213: Where appropriate, use 'macOS' in idlelib.
-
-bpo-34864: Document two IDLE on MacOS issues.  The System Preferences
-Dock "prefer tabs always" setting disables some IDLE features.
-Menus are a bit different than as described for Windows and Linux.
-
-bpo-35202: Remove unused imports in idlelib.
-
-bpo-33000: Document that IDLE's shell has no line limit.
-A program that runs indefinitely can overfill memory.
-
-bpo-23220: Explain how IDLE's Shell displays output.
-Add new subsection "User output in Shell".
-
-bpo-35099: Improve the doc about IDLE running user code.
-"IDLE -- console differences" is renamed "Running user code".
-It mostly covers the implications of using custom sys.stdxxx objects.
-
-bpo-35097: Add IDLE doc subsection explaining editor windows.
-Topics include opening, title and status bars, .py* extension, and running.
-
-Issue 35093: Document the IDLE document viewer in the IDLE doc.
-Add a paragraph in "Help and preferences", "Help sources" subsection.
-
-bpo-1529353: Explain Shell text squeezing in the IDLE doc.
-
-bpo-35088: Update idlelib.help.copy_string docstring.
-We now use git and backporting instead of hg and forward merging.
-
-bpo-35087: Update idlelib help files for the current doc build.
-The main change is the elimination of chapter-section numbers.
-
-bpo-1529353: Output over N lines (50 by default) is squeezed down to a button.
-N can be changed in the PyShell section of the General page of the
-Settings dialog.  Fewer, but possibly extra long, lines can be squeezed by
-right clicking on the output.  Squeezed output can be expanded in place
-by double-clicking the button or into the clipboard or a separate window
-by right-clicking the button.
-
-bpo-34548: Use configured color theme for read-only text views.
-
-bpo-33839: Refactor ToolTip and CallTip classes; add documentation
-and tests.
-
-bpo-34047: Fix mouse wheel scrolling direction on macOS.
-
-bpo-34275: Make calltips always visible on Mac.
-Patch by Kevin Walzer.
-
-bpo-34120: Fix freezing after closing some dialogs on Mac.
-This is one of multiple regressions from using newer tcl/tk.
-
-bpo-33975: Avoid small type when running htests.
-Since part of the purpose of human-viewed tests is to determine that
-widgets look right, it is important that they look the same for
-testing as when running IDLE.
-
-bpo-33905: Add test for idlelib.stackview.StackBrowser.
-
-bpo-33924: Change mainmenu.menudefs key 'windows' to 'window'.
-Every other menudef key is the lowercase version of the
-corresponding main menu entry (in this case, 'Window').
-
-bpo-33906: Rename idlelib.windows as window
-Match Window on the main menu and remove last plural module name.
-Change imports, test, and attribute references to match new name.
-
-bpo-33917: Fix and document idlelib/idle_test/template.py.
-The revised file compiles, runs, and tests OK.  idle_test/README.txt
-explains how to use it to create new IDLE test files.
-
-bpo-33904: In rstrip module, rename class RstripExtension as Rstrip.
-
-bpo-33907: For consistency and clarity, rename calltip objects.
-Module calltips and its class CallTips are now calltip and Calltip.
-In module calltip_w, class CallTip is now CalltipWindow.
-
-bpo-33855: Minimally test all IDLE modules.
-Standardize the test file format.  Add missing test files that import
-the tested module and perform at least one test.  Check and record the
-coverage of each test.
-
-bpo-33856: Add 'help' to Shell's initial welcome message.
-
-
-What's New in IDLE 3.7.0 (since 3.6.0)
-Released on 2018-06-27
-======================================
-
-bpo-33656: On Windows, add API call saying that tk scales for DPI.
-On Windows 8.1+ or 10, with DPI compatibility properties of the Python
-binary unchanged, and a monitor resolution greater than 96 DPI, this
-should make text and lines sharper and some colors brighter.
-On other systems, it should have no effect.  If you have a custom theme,
-you may want to adjust a color or two.  If perchance it make text worse
-on your monitor, you can disable the ctypes.OleDLL call near the top of
-pyshell.py and report the problem on python-list or idle-dev@python.org.
-
-bpo-33768: Clicking on a context line moves that line to the top
-of the editor window.
-
-bpo-33763: Replace the code context label widget with a text widget.
-
-bpo-33664: Scroll IDLE editor text by lines.
-(Previously, the mouse wheel and scrollbar slider moved text by a fixed
-number of pixels, resulting in partial lines at the top of the editor
-box.)  This change also applies to the shell and grep output windows,
-but currently not to read-only text views.
-
-bpo-33679: Enable theme-specific color configuration for Code Context.
-(Previously, there was one code context foreground and background font
-color setting, default or custom, on the extensions tab, that applied
-to all themes.)  For built-in themes, the foreground is the same as
-normal text and the background is a contrasting gray.  Context colors for
-custom themes are set on the Hightlights tab along with other colors.
-When one starts IDLE from a console and loads a custom theme without
-definitions for 'context', one will see a warning message on the
-console.
-
-bpo-33642: Display up to maxlines non-blank lines for Code Context.
-If there is no current context, show a single blank line.  (Previously,
-the Code Contex had numlines lines, usually with some blank.)  The use
-of a new option, 'maxlines' (default 15), avoids possible interference
-with user settings of the old option, 'numlines' (default 3).
-
-bpo-33628: Cleanup codecontext.py and its test.
-
-bpo-32831: Add docstrings and tests for codecontext.py.
-Coverage is 100%.  Patch by Cheryl Sabella.
-
-bpo-33564: Code context now recognizes async as a block opener.
-
-bpo-21474: Update word/identifier definition from ascii to unicode.
-In text and entry boxes, this affects selection by double-click,
-movement left/right by control-left/right, and deletion left/right
-by control-BACKSPACE/DEL.
-
-bpo-33204: Consistently color invalid string prefixes.
-A 'u' string prefix cannot be paired with either 'r' or 'f'.
-IDLE now consistently colors as much of the prefix, starting at the
-right, as is valid.  Revise and extend colorizer test.
-
-bpo-32984: Set __file__ while running a startup file.
-Like Python, IDLE optionally runs 1 startup file in the Shell window
-before presenting the first interactive input prompt.  For IDLE,
-option -s runs a file named in environmental variable IDLESTARTUP or
-PYTHONSTARTUP; -r file runs file.  Python sets __file__ to the startup
-file name before running the file and unsets it before the first
-prompt.  IDLE now does the same when run normally, without the -n
-option.
-
-bpo-32940: Replace StringTranslatePseudoMapping with faster code.
-
-bpo-32916: Change 'str' to 'code' in idlelib.pyparse and users.
-
-bpo-32905: Remove unused code in pyparse module.
-
-bpo-32874: IDLE - add pyparse tests with 97% coverage.
-
-bpo-32837: IDLE - require encoding argument for textview.view_file.
-Using the system and place-dependent default encoding for open()
-is a bad idea for IDLE's system and location-independent files.
-
-bpo-32826: Add "encoding=utf-8" to open() in IDLE's test_help_about.
-GUI test test_file_buttons() only looks at initial ascii-only lines,
-but failed on systems where open() defaults to 'ascii' because
-readline() internally reads and decodes far enough ahead to encounter
-a non-ascii character in CREDITS.txt.
-
-bpo-32765: Update configdialog General tab create page docstring.
-Add new widgets to the widget list.
-
-bpo-32207: Improve tk event exception tracebacks in IDLE.
-When tk event handling is driven by IDLE's run loop, a confusing
-and distracting queue.EMPTY traceback context is no longer added
-to tk event exception tracebacks.  The traceback is now the same
-as when event handling is driven by user code.  Patch based on
-a suggestion by Serhiy Storchaka.
-
-bpo-32164: Delete unused file idlelib/tabbedpages.py.
-Use of TabbedPageSet in configdialog was replaced by ttk.Notebook.
-
-bpo-32100: Fix old and new bugs in pathbrowser; improve tests.
-Patch mostly by Cheryl Sabella.
-
-bpo-31860: The font sample in the settings dialog is now editable.
-Edits persist while IDLE remains open.
-Patch by Serhiy Storchake and Terry Jan Reedy.
-
-bpo-31858: Restrict shell prompt manipulation to the shell.
-Editor and output windows only see an empty last prompt line.  This
-simplifies the code and fixes a minor bug when newline is inserted.
-Sys.ps1, if present, is read on Shell start-up, but is not set or changed.
-Patch by Terry Jan Reedy.
-
-bpo-28603: Fix a TypeError that caused a shell restart when printing
-a traceback that includes an exception that is unhashable.
-Patch by Zane Bitter.
-
-bpo-13802: Use non-Latin characters in the Font settings sample.
-Even if one selects a font that defines a limited subset of the unicode
-Basic Multilingual Plane, tcl/tk will use other fonts that define a
-character.  The expanded example give users of non-Latin characters
-a better idea of what they might see in the shell and editors.
-
-To make room for the expanded sample, frames on the Font tab are
-re-arranged.  The Font/Tabs help explains a bit about the additions.
-Patch by Terry Jan Reedy
-
-bpo-31460: Simplify the API of IDLE's Module Browser.
-Passing a widget instead of an flist with a root widget opens the
-option of creating a browser frame that is only part of a window.
-Passing a full file name instead of pieces assumed to come from a
-.py file opens the possibility of browsing python files that do not
-end in .py.
-
-bpo-31649: Make _htest and _utest parameters keyword-only.
-These are used to adjust code for human and unit tests.
-
-bpo-31459: Rename module browser from Class Browser to Module Browser.
-The original module-level class and method browser became a module
-browser, with the addition of module-level functions, years ago.
-Nested classes and functions were added yesterday.  For back-
-compatibility, the virtual event <<open-class-browser>>, which
-appears on the Keys tab of the Settings dialog, is not changed.
-Patch by Cheryl Sabella.
-
-bpo-1612262: Module browser now shows nested classes and functions.
-Original patches for code and tests by Guilherme Polo and
-Cheryl Sabella, respectively.  Revisions by Terry Jan Reedy.
-
-bpo-31500: Tk's default fonts now are scaled on HiDPI displays.
-This affects all dialogs.  Patch by Serhiy Storchaka.
-
-bpo-31493: Fix code context update and font update timers.
-Canceling timers prevents a warning message when test_idle completes.
-
-bpo-31488: Update non-key options in former extension classes.
-When applying configdialog changes, call .reload for each feature class.
-Change ParenMatch so updated options affect existing instances attached
-to existing editor windows.
-
-bpo-31477: Improve rstrip entry in IDLE doc.
-Strip Trailing Whitespace strips more than blank spaces.
-Multiline string literals are not skipped.
-
-bpo-31480: fix tests to pass with zzdummy extension disabled. (#3590)
-To see the example in action, enable it on options extensions tab.
-
-bpo-31421: Document how IDLE runs tkinter programs.
-IDLE calls tcl/tk update in the background in order to make live
-interaction and experimentation with tkinter applications much easier.
-
-bpo-31414: Fix tk entry box tests by deleting first.
-Adding to an int entry is not the same as deleting and inserting
-because int('') will fail.  Patch by Terry Jan Reedy.
-
-bpo-27099: Convert IDLE's built-in 'extensions' to regular features.
-  About 10 IDLE features were implemented as supposedly optional
-extensions.  Their different behavior could be confusing or worse for
-users and not good for maintenance.  Hence the conversion.
-  The main difference for users is that user configurable key bindings
-for builtin features are now handled uniformly.  Now, editing a binding
-in a keyset only affects its value in the keyset.  All bindings are
-defined together in the system-specific default keysets in config-
-extensions.def.  All custom keysets are saved as a whole in config-
-extension.cfg.  All take effect as soon as one clicks Apply or Ok.
-   The affected events are '<<force-open-completions>>',
-'<<expand-word>>', '<<force-open-calltip>>', '<<flash-paren>>',
-'<<format-paragraph>>', '<<run-module>>', '<<check-module>>', and
-'<<zoom-height>>'.  Any (global) customizations made before 3.6.3 will
-not affect their keyset-specific customization after 3.6.3. and vice
-versa.
-  Initial patch by Charles Wohlganger, revised by Terry Jan Reedy.
-
-bpo-31051:  Rearrange condigdialog General tab.
-Sort non-Help options into Window (Shell+Editor) and Editor (only).
-Leave room for the addition of new options.
-Patch by Terry Jan Reedy.

-bpo-30617: Add docstrings and tests for outwin subclass of editor.
-Move some data and functions from the class to module level.
-Patch by Cheryl Sabella.

-Patch by Cheryl Sabella.
-
-bpo-19903: Change calltipes to use inspect.signature.
-Idlelib.calltips.get_argspec now uses inspect.signature instead of
-inspect.getfullargspec, like help() does.  This improves the signature
-in the call tip in a few different cases, including builtins converted
-to provide a signature.  A message is added if the object is not
-callable, has an invalid signature, or if it has positional-only
-parameters.  Patch by Louie Lu.
-
-bop-31083: Add an outline of a TabPage class in configdialog.
-Add template as comment. Update existing classes to match outline.

-broken by the switch to ttk.Notebook is fixed.
-Patch mostly by Cheryl Sabella.

-bpo-30781: IDLE - Use ttk Notebook in ConfigDialog.
-This improves navigation by tabbing.
-Patch by Terry Jan Reedy.
-
-bpo-31060: IDLE - Finish rearranging methods of ConfigDialog.
-Grouping methods pertaining to each tab and the buttons will aid
-writing tests and improving the tabs and will enable splitting the
-groups into classes.
-Patch by Terry Jan Reedy.
-
-bpo-30853: IDLE -- Factor a VarTrace class out of ConfigDialog.
-Instance tracers manages pairs consisting of a tk variable and a
-callback function.  When tracing is turned on, setting the variable
-calls the function.  Test coverage for the new class is 100%.
-Patch by Terry Jan Reedy.
-
-bpo-31003: IDLE: Add more tests for General tab.
-Patch by Terry Jan Reedy.
-
-bpo-30993: IDLE - Improve configdialog font page and tests.
-*In configdialog: Document causal pathways in create_font_tab
-docstring.  Simplify some attribute names. Move set_samples calls to
-var_changed_font (idea from Cheryl Sabella).  Move related functions to
-positions after the create widgets function.
-* In test_configdialog: Fix test_font_set so not order dependent.  Fix
-renamed test_indent_scale so it tests the widget.  Adjust tests for
-movement of set_samples call.  Add tests for load functions.  Put all
-font tests in one class and tab indent tests in another.  Except for
-two lines, these tests completely cover the related functions.
-Patch by Terry Jan Reedy.

-
-- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
-  debugger is active (15347); b) closing the debugger with the [X] button
-  (15348); and c) activating the debugger when already active (24455).
-  The patch by Mark Roseman does this by making two changes.

-  Strings, comments, keywords, ... are still green, red, orange, ... .
-  To use it with IDLEs released before November 2015, hit the
-  'Save as New Custom Theme' button and enter a new name,
-  such as 'Custom Dark'.  The custom theme will work with any IDLE
-  release, and can be modified.
