Release History

  • 2.1.3 10 June, 2025
    • Decide whether to call magick or convert more intelligently. This adds Windows support, without breaking JPT on Ubuntu or other distros that only ship an ancient version of ImageMagick. Thanks to @MUmarShahbaz for #324
  • 2.1.2 13 September, 2024
    • Remove overly specific version spec for ruby-vips - thanks to @hschne for #313
  • 2.1.1 20 July, 2024
    • Don't provide Q setting for PPM images - thanks to @dichiban for #309
    • Fix alpha premultiplication - thanks to @KaarlisCaune for #302
  • 2.1.0 29 January, 2024
    • Check whether the vips CLI is installed before trying to use it. Thanks to @philrb for #299
    • Update minimum required mocha version to maintain compatibility with minitest
  • 2.0.4 August 16, 2022
    • Fix backend format support detection for new versions of libvips & imagemagick
  • 2.0.3 April 1, 2021
    • Improve backend format support detection
  • 2.0.2 March 31, 2021
    • Do not pass a quality argument when generating PNG files.
      • It only works on newer versions of vips, breaking builds when using older versions (such as when deploying to netlify.)
      • It's not remarkably useful in the first place.
  • 2.0.1 March 31, 2021
    • Select imagemagick deliberately when appropriate, rather than simply rescuing all vips errors and trying again. This will stop JPT from suppressing useful vips errors.
  • 2.0 March 25, 2021 - Migration guide
    • Switch from ImageMagick to libvips.
      • 🚀🔥🔥MUCH MORE FASTER🔥🔥🚀
      • Will still attempt to use imagemagick if libvips cannot handle a particular image format.
      • Eliminate the ImageMagick v7 on Ubuntu pain we've been dealing with for so long.
    • Require Ruby >= 2.6, support Ruby 3.0
    • Require Jekyll >= 4.0
    • Cropping is changing.
      • We now use the libvips smartcrop function, which does some magic to keep the most useful part of the image.
      • Geometry is renamed to ‘crop', and reduced to simple aspect ratios only. (width:height)
      • Gravity is gone, replaced by ‘keep' which is translated to a libvips interestingness setting.
    • Add stock presets and media queries, under the jpt- prefix.
    • Add format_quality default settings for webp, avif, and jp2.
    • Add image-format-specific write options.
    • Overhaul user input handling; we can now validate inputs and give error messages which are less useless. Stronger validation and nicer errors will be added in future releases.
    • Drop support for markup_presets and media_presets. They are now officially and only presets and media_queries.
    • Improve docs with an introductory tutorial and ‘how-to' flow.
  • 1.14.0 January 10, 2021
    • Gracefully handle empty tag arguments.
    • Re-add metadata stripping. I removed it inadvertently when refactoring; now there's a test and a setting to turn it off.
    • Respect Jekyll's --disable-disk-cache argument.
    • Add baseurl configuration, allowing increased plugin support (such as I18n via jekyll-multiple-languages-plugin)
    • Tooling & test suite maintenance and improvements.
  • 1.13.0 November 23, 2020
    • Add image quality interpolation; allows for variable image quality based on image size.
    • Bugfix: Perform format, resize, and quality changes simultaneously rather than individually.
      • Allows for actual lossless webp: simply set quality to 100.
      • Improves fresh (no cached images) build times by ~15%
      • Fix problems with poor image quality.
  • 1.12.0 July 30, 2020
    • Documentation overhaul. Now with 87% less scrolling!
    • Rename markup_presets and media_presets to presets and media_queries. The old names were bad and caused confusion. The old names will continue to work until the next major version is released.
  • 1.11.0 July 27, 2020
    • Width and height attribute support! Begone, page reflow.
    • Cache image information between builds
    • Change image naming format. This update will trigger all images to be regenerated, so you may want to delete your generated images folder beforehand.

    • Bugfix for fallback image files not actually getting generated
  • 1.10.1 July 2, 2020

  • 1.9.0 Feb 2, 2020

    • Bugfix: Minor fix to nomarkdown wrapper output
    • link_source will now target the base source image, rather than finding the biggest one.
