libvips v8.9.0 Release Notes

Release Date: 2019-12-09 // over 4 years ago

  • 🏁 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.

    👀 See this blog post for a summary of the new features in 8.9.
