- MBString:
  . mb_detect_encoding is better able to identify the correct encoding for
    Turkish text. (Alex Dowad)
  . mb_detect_encoding's "non-strict" mode now behaves as described in the
    documentation. Previously, it would return false if the same byte
    (for example, the first byte) of the input string was invalid in all
    candidate encodings. More generally, it would eliminate candidate
    encodings from consideration when an invalid byte was seen, and if the
    same input byte eliminated all remaining encodings still under
    consideration, it would return false. On the other hand, if all candidate
    encodings but one were eliminated from consideration, it would return the
    last remaining one without regard for how many encoding errors might be
    encountered later in the string. This is different from the behavior
    described in the documentation, which says: "If strict is set to false,
    the closest matching encoding will be returned." (Alex Dowad)
  . mb_strtolower, mb_strtotitle, and mb_convert_case implement conditional
    casing rules for the Greek letter sigma. For mb_convert_case, conditional
    casing only applies to MB_CASE_LOWER and MB_CASE_TITLE modes, not to
    MB_CASE_LOWER_SIMPLE and MB_CASE_TITLE_SIMPLE. (Alex Dowad)
  . mb_detect_encoding is better able to identify UTF-8 and UTF-16 strings
    with a byte-order mark. (Alex Dowad)
  . mb_decode_mimeheader interprets underscores in QPrint-encoded MIME
    encoded words as required by RFC 2047; they are converted to spaces.
    Underscores must be encoded as "=5F" in such MIME encoded words.
    (Alex Dowad)
  . mb_encode_mimeheader no longer drops NUL (zero) bytes when
    QPrint-encoding the input string. This previously caused strings in
    certain text encodings, especially UTF-16 and UTF-32, to be
    corrupted by mb_encode_mimeheader. (Alex Dowad)
  . Implement mb_str_pad() RFC. (nielsdos)
  . Fixed bug GH-11514 (PHP 8.3 build fails with --enable-mbstring enabled).
    (nielsdos)

  . Added OPENSSL_CMS_OLDMIMETYPE and PKCS7_NOOLDMIMETYPE contants to switch

    (Florian Moser)
  . Added support for additional EC parameters in openssl_pkey_new. (Eno-CN)

- PCNTL:
