Upstream NEWS:

  DEPRECATION WARNING for 4.6.0:

    This version will be the last one supporting most TIFF tools
    (except tiffinfo, tiffdump, tiffcp and tiffset), whose maintenance
    will be discontinued, due to the lack of contributors able to
    address reported security issues. Starting with libtiff v4.6.0,
    their source code, at this time ,will still be available in the
    source distribution, but they will no longer be built by default,
    and issues related to them will no longer be accepted in the
    libtiff bug tracker.

  New/improved functionalities:

    Hardcode HOST_FILLORDER to FILLORDER_LSB2MSB and make 'H' flag of
    TIFFOpen() to warn and an alias of FILLORDER_MSB2LSB. tif_lerc.c:
    use WORDS_BIGENDIAN instead of HOST_BIGENDIAN.
