Pending removal in Python 3.19
******************************

* "ctypes":

  * Implicitly switching to the MSVC-compatible struct layout by
    setting "_pack_" but not "_layout_" on non-Windows platforms.

* "hashlib":

  * In hash function constructors such as "new()" or the direct hash-
    named constructors such as "md5()" and "sha256()", their optional
    initial data parameter could also be passed a keyword argument
    named "data=" or "string=" in various "hashlib" implementations.

    Support for the "string" keyword argument name is now deprecated
    and slated for removal in Python 3.19.

    Before Python 3.13, the "string" keyword parameter was not
    correctly supported depending on the backend implementation of
    hash functions. Prefer passing the initial data as a positional
    argument for maximum backwards compatibility.

* "http.cookies":

  * "http.cookies.Morsel.js_output()" is deprecated and will be
    removed in Python 3.19.

  * "http.cookies.BaseCookie.js_output()" is deprecated and will be
    removed in Python 3.19.

* "imaplib":

  * Altering "IMAP4.file" is now deprecated and slated for removal in
    Python 3.19. This property is now unused and changing its value
    does not automatically close the current file.

    Before Python 3.14, this property was used to implement the
    corresponding "read()" and "readline()" methods for "IMAP4" but
    this is no longer the case since then.

* "tkinter":

  * "tkinter.filedialog.askopenfiles()" has been deprecated since
    Python 3.16.  Iterate over the names returned by
    "askopenfilenames()" and open them one by one instead.
