Prompt-toolkit

------------------

New features:
- Pass through `name` property in `TextArea` widget to `Buffer`.
- Added a `enable_cpr` parameter to `Vt100_Output`, `TelnetServer` and
`PromptToolkitSSHServer`, to completely disable CPR support instead of
automatically detecting it.

------------------

New features:
- Allow zero-width-escape sequences in `print_formatted_text`.
- Add default value option for input dialog.
- Added `has_suggestion` filter.

Fixes:
- Fix rendering of control-shift-6 (or control-^). Render as '^^'
- Always wrap lines in the Label widget by default.
- Fix enter key binding in system toolbar in Vi mode.
- Improved handling of stdout objects that don't have a 'buffer' attribute. For
instance, when using `renderer_print_formatted_text` in a Jupyter Notebook.

------------------

New features:
- Accept 'handle_sigint' parameter in PromptSession.

Fixes
- Fix 'variable referenced before assignment' error in vt100 mouse bindings.
- Pass `handle_sigint` from `Application.run` to `Application.run_async`.
- Fix detection of telnet client side changes.
- Fix `print_container` utility (handle `EOFError`).

Breaking changes:
- The following are now context managers:
`create_pipe_input`, `PosixPipeInput` and `Win32PipeInput`.

------------------

New features:
- Support format specifiers for HTML and ANSI formatted text.
- Accept defaults for checkbox and radio list, and their corresponding dialogs.

Fixes:
- Fix resetting of cursor shape after the application terminates.

------------------

New features:
- Support for cursor shapes. The cursor shape for prompts/applications can now
be configured, either as a fixed cursor shape, or in case of Vi input mode,
according to the current input mode.
- Handle "cursor forward" command in ANSI formatted text. This makes it
possible to render many kinds of generated ANSI art.
- Accept `align` attribute in `Label` widget.
- Added `PlainTextOutput`: an output implementation that doesn't render any
ANSI escape sequences. This will be used by default when redirecting stdout
to a file.
- Added `create_app_session_from_tty`: a context manager that enforces
input/output to go to the current TTY, even if stdin/stdout are attached to
pipes.
- Added `to_plain_text` utility for converting formatted text into plain text.

Fixes:
- Don't automatically use `sys.stderr` for output when `sys.stdout` is not a
TTY, but `sys.stderr` is. The previous behavior was confusing, especially
when rendering formatted text to the output, and we expect it to follow
redirection.

------------------

Fixes:
- Fixes issue introduced in 3.0.25: Don't handle SIGINT on Windows.
