Bug fixes:
* TIFF: Default the alpha channel to type EXTRASAMPLE_UNASSALPHA(2).
* BMP: Many fixes for reading esoteric BMP sub-formats.
* TranslateTextEx(): Revert change so now a NULL pointer is returned
when given an empty string. Some algorithms (e.g. montage) were
depending on this!.
* PAM: Fix reading comments.
* PNG: Added Add missing module aliases "PNG00", "PNG48", "PNG64", so
it is again possible to request these subformats directly.
* TIFF: For common formats with the required number of channels, but
one is an 'unspecified' channel, promote unspecified alpha to
unassociated alpha so that the alpha channel is not ignored.
* "Magick" command line emulation: Eliminate duplicate utility name
output in error messages
New Features:
* BMP: Added the ability to read and write BMP using JPEG compression.
Use '-define bmp:allow-jpeg' to allow use of JPEG compression.
* BMP: Added support for BI_ALPHABITFIELDS compression
* BMP: Added support for reading BMP with PNG compression.

Bug fixes:
* Blob: Immediately reject attempts to write blobs to formats which
can not support blobs.
* TranslateTextEx(): An empty string argument should return an empty
string rather than a NULL string.
* SetImageAttribute(): Fix bounds issue when concatenating string.
* JPEG: Do not set image resolution if the values provided are outside
of the valid range.
* Fixes for NaN when reading formats based on floating point.
* HEIF: Fix reading images with rotation/transformation.
* BMP: Do not decode primaries or gamma unless colorspace is
LCS_CALIBRATED_RGB. Add/correct bmp_info.size "biSize" logic which
decides if header chunks are present (or invalid).
* MNG: Fixes for resizing using X_method 5.
* GM command (convert, montage, mogrify): Many command-line parser
fixes/checks for invalid command line syntax which causes unexpected
behavior, or core dumps.
* TopoL: Given that a writer is now provided, issues found in the
reader (and writer) due to continual fuzz-testing have been fixed,
as encountered.
* GetImageClippingPathAttribute(): Check for and use clipping path
name (ID=2999) to get the real attribute name.
* ReadIPTCProfile(): Fix malformed IPTC data parsing.
New Features:
* TopoL: Now provides a writer.
* WPG: Now provides a writer.
* gm batch: Implement simple Test Anything Protocol (TAP) test
counting and "ok N"/"not ok N" messaging.

* GetMagickGeometry(): Fix a scaling issue where dimensions could be
scaled down to zero.
* PCD: Handle writing image with a dimension of 1.
* PNG: When writing, use lower-case raw profile identifiers (e.g. 'Raw
profile type xmp') because exiftool expects that.
* SUN: The sense of monochrome images was inverted. Fix scanline size
calculation.
* WPG: Fix 20-year old bug in WPG header reading.
New Features:
* JXL: Decode and log extra channel information. This information is
not yet used.
* PCX and DCX: Support writing uncompressed format (use -compress none
for no compression).
* Added IM1, IM8, and IM24 magick aliases for the Sun Raster format
since those are the historically correct extensions.
API Updates:
* AppendImageToList() now updates the image list pointer to be the
image which was just added. Use GetFirstImageInList() when the
pointer to the first image in the list is needed.

Special Issues:
* The FTP site ftp.graphicsmagick.org is now shut down due to a lack
of bandwith, extremely abusive users (including from Google and
customers of Amazon Web Services), and a lack of support from the
user community. Another factor is that FTP support has been removed
from popular web browsers. This is very unfortunate since the site
served multiple usages, including providing a lot of historical data
(e.g. related to PNG) which may not be available elsewhere.
* GraphicsMagick really does need some additional productive
volunteers. For several years now, the burden has entirely been on
me (Bob Friesenhahn). I have been sheparding the project for 20
years already (and contributed to ImageMagick and GraphicsMagick
combined for 26 years already). It is not reasonable to expect
someone with a full time job (and expecting to retire in a few
years) to do all of the work.
Security Fixes:
* GraphicsMagick is participating in Google's oss-fuzz project due to
the contributions and assistance of Alex Gaynor. Since February 4
2018, ??? issues have been opened by oss-fuzz and ?? issues remain
open. The issues list is available at
https://bugs.chromium.org/p/oss-fuzz/issues/list under search term
"graphicsmagick". Issues are available for anyone to view and
duplicate if they have been in "Verified" status for 30 days, or if
they have been in "New" status for 90 days. Please consult the
GraphicsMagick ChangeLog file, Mercurial repository commit log, and
the oss-fuzz issues list for details.
Bug fixes:
* Documentation: Generator scripts in 'doc' directory now produce
similar results using GNU sed and Solaris/Illumos sed and don't

Special Issues:
* Firmware and operating system updates to address the Spectre
vulnerability (and possibly to some extent the Meltdown
vulnerability) have substantially penalized GraphicsMagick's OpenMP
performance. Performance is reduced even with GCC 7 and 8's
improved optimizers. There does not appear to be anything we can do
about this.
Security Fixes:
* GraphicsMagick is now participating in Google's oss-fuzz project due
to the contributions and assistance of Alex Gaynor.
Bug fixes:
* See above note about oss-fuzz fixes.
* CINEON: Fix unexpected hang on a crafted Cineon image. SourceForge
issue 571.
* Drawing recursion is limited to 100 and may be tuned via the
MAX_DRAWIMAGE_RECURSION pre-processor definition.
* Fix reading MIFF files using legacy keyword 'color-profile' for ICC
color profile as was used by ImageMagick 4.2.9.
* Fix reading/writing files when 'magick' is specified in lower case.
This bug was a regression in 1.3.30.
New Features:
* TIFF: Support Zstd compression in TIFF. This requires libtiff
4.0.10 or later.
* TIFF: Support WebP compression in TIFF. This requires libtiff
4.0.10 or later.
