1. Commit any unsaved changes.
2. Create html/vX.X.html. Take ChangeLog entries and html-ify in there.
2. Create html/vX.X.html and add it to cvs with 'cvs add html/vX.X.html'.
Take ChangeLog entries and html-ify in there.
Easist thing to do is take html/vX.(X-1).html and use it as a template.
Add that file to the list of EXTRA_DIST files in the html/Makefile.am.

<li> TIFFCheckDirOffset(): avoid uint16 overflow
when reading more than 65535 directories, and effectively error out when
eaching that limit.
<li> TIFFNumberOfDirectories(): generate error in case of directory count
overflow.
<li> TIFFAdvanceDirectory(): If nextdir is found to
be defective, then set it to zero before returning error in order
to terminate processing of truncated TIFF.
<li> JPEG-in-TIFF: recognize SOF2, SOF9 and SOF10
markers to avoid emitting a warning. Fix for compatibility with mozjpeg library.
Note: the default settings of mozjpeg will produce progressive scans, which
is forbidden by the TechNote.
<li> JPEG-in-TIFF: Fix regression introduced in 3.9.3/4.0.0 that caused
all tiles/strips to include quantization tables even when the jpegtablesmode
had the JPEGTABLESMODE_QUANT bit set.
Also add explicit removal of Huffman tables when jpegtablesmode has the
JPEGTABLESMODE_HUFF bit set, which avoids Huffman tables to be emitted in the
first tile/strip (only useful in update scenarios. create-only was
fine)
<li> JPEG-in-TIFF: fix segfault in JPEGFixupTagsSubsampling() on
corrupted image where tif->tif_dir.td_stripoffset == NULL.
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2471">#2471</a>)
<li> NeXT codec: add new tests to check that we don't read outside of
the compressed input stream buffer.
<li> NeXT codec: check that BitsPerSample = 2. Fixes
<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2487">#2487</a> (CVE-2014-8129)
<li> NeXT codec: in the "run mode", use tilewidth for tiled images
instead of imagewidth to avoid crash
<li> tif_getimage.c: in OJPEG case, fix checks on strile width/height
in the putcontig8bitYCbCr42tile, putcontig8bitYCbCr41tile and
putcontig8bitYCbCr21tile cases.
<li> in TIFFDefaultDirectory(), reset any already existing
extented tags installed by user code through the extender mechaninm before
calling the extender callback (GDAL #5054)
<li> Fix warnings about unused parameters.
<li> Fix various typos in comments found by Debian lintian tool (GDAL #5756)
<li> tif_getimage.c: avoid divide by zero on invalid YCbCr subsampling.
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2235">#2235</a>)
<li> tif_dirread.c: In EstimateStripByteCounts(), check return code
of _TIFFFillStriles(). This solves crashing bug on corrupted
images generated by afl.
<li>tif_read.c: fix several invalid comparisons of a uint64 value with
&lt;= 0 by casting it to int64 first. This solves crashing bug on corrupted
images generated by afl.
<li>TIFFSetField(): refuse to set negative values for
TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION that cause asserts when writing
the directory
<li>TIFFReadDirectory(): refuse to read ColorMap or
TransferFunction if BitsPerSample has not yet been read, otherwise reading
it later will cause user code to crash if BitsPerSample > 1
<li> TIFFRGBAImageOK(): return FALSE if LOGLUV with
SamplesPerPixel != 3, or if CIELAB with SamplesPerPixel != 3 or BitsPerSample != 8
<li> tif_config.vc.h: no longer use "#define snprintf _snprintf" with
Visual Studio 2015 aka VC 14 aka MSVC 1900
<li> LZW codec: prevent potential null dereference of sp->dec_codetab in LZWPreDecode
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2459">#2459</a>)
<li> TIFFReadBufferSetup(): avoid passing -1 size
to TIFFmalloc() if passed user buffer size is 0
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2459">#2459</a>)
<li> TIFFReadDirEntryOutputErr(): Incorrect
count for tag should be a warning rather than an error since
errors terminate processing.
<li> tif_dirinfo.c (TIFFField) : Fix data type for TIFFTAG_GLOBALPARAMETERSIFD tag.
<li> Add definitions for TIFF/EP CFARepeatPatternDim and CFAPattern tags
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2457">#2457</a>)
<li> tif_codec.c, tif_dirinfo.c: Enlarge some fixed-size buffers that weren't
large enough, and eliminate substantially all uses of sprintf(buf,
...) in favor of using snprintf(buf, sizeof(buf), ...)
<li> configure.ac: Improve pkg-config static linking by adding -lm to Libs.private when needed.
<li> tif_write.c: tmsize_t related casting warning fixed for
64bit linux.
<li> tif_read.c: uint64/tmsize_t change for MSVC warnings.
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2427">#2427</a>)
<li> Fix TIFFPrintDirectory's handling of
field_passcount fields: it had the TIFF_VARIABLE and
TIFF_VARIABLE2 cases backwards.
<li> PixarLog codec: Improve previous patch for CVE-2012-4447
(to enlarge tbuf for possible partial stride at end) so that
overflow in the integer addition is detected.
<li>tif_{unix,vms,win32}.c (_TIFFmalloc): ANSI C does not
require malloc() to return NULL pointer if requested allocation
size is zero. Assure that _TIFFmalloc does.
<li>tif_zip.c: Avoid crash on NULL error messages.

<li> tiff2pdf: fix crash due to invalid tile count.
<li> tiff2pdf: Detect invalid settings of BitsPerSample/SamplesPerPixel for CIELAB / ITULAB
<li> tiff2pdf: Assure that memory size calculations for
_TIFFmalloc() do not overflow the range of tmsize_t.

<li> tiff2pdf: Rewrite JPEG marker parsing in

<li> tiff2rgba: fix usage message in that zip was wrongly described
<li> tiffinfo: Default various values fetched with TIFFGetField() to avoid being uninitialized.

Enlarge some fixed-size buffers that weren't

...) in favor of using snprintf(buf, sizeof(buf), ...), so as to
protect against overflow of fixed-size buffers. This responds in
particular to CVE-2013-1961 concerning overflow in tiff2pdf.c's
t2p_write_pdf_page().
