See this blog post for a summary of the new features in 8.11.

Windows binaries are here:

The libvips Windows binary vips-dev-w64-all-x.y.z.zip contains ALL the file format loaders that libvips supports, including some very minor ones, and a complete copy of ImageMagick. It can process many different file types, but it is also rather vulnerable to hacking.

The vips-dev-w64-web-x.y.z.zip build contains only file format loaders that have been carefully tested and which are commonly used on the web. It won't load formats like openslide (for example), but it should be safer to use with untrusted input.

• add vipsjpegloadsource() and vipssvgloadsource() to public C API
• integrate doxygen in build system to generate C++ API docs
• improve C++ API doc comments

• add vipssourceginputstream_new() to load images from a GInputStream
• add openslideloadsource(), vipsloadsource(), vipssave_target()
• add hist path to rank for large windows on uchar images
• better 8/16-bit choice for pngsave
• avoid NaN in mapim [afontenot]

• fix ref leaks in mosaicing package
• run libvips leak test in CI
• add vipsfitsloadsource(), vipsniftiloadsource()
• png and gif load note background colour as metadata [781545872]
• add vipsimage[set|get]arraydouble()
• add GIF load with libnsgif
• add jp2kload, jp2ksave
• add jp2k compression to tiff load and save
• add JPEG-XL load and save
• add blackpointcompensation flag for icc transforms

libvips - v8.6.3

The libvips binary vips-dev-w64-all-x.y.z.zip contains ALL the file format loaders that libvips supports, including some very minor ones, and a complete copy of ImageMagick. It can process many different file types, but it is also rather vulnerable to hacking.

The vips-dev-w64-web-x.y.z.zip build contains only file format loaders that have been carefully tested and which are commonly used on the web. It won't load formats like openslide (for example), but it should be much safer to use with untrusted input images.

• the 8.6.3-1 windows builds fix a crash in libz configuation
• use pkg-config to find libjpeg, if we can
• better clean of output image in vips_image_write() fixes a crash writing twice to memory
• better rounding behaviour in convolution means we hit the vector path more often
• fix a crash if a delayed load failed [gsharpsh00ter]
• icc_import attaches the fallback profile if it used it, making vipsthumbnail behaviour with untagged CMYK images saner

• fix read of plane-separate TIFFs with large strips [remicollet]
• fix a C++ warning in composite.cpp [lovell]
