v11.0.0

Breaking Changes

• Replaced imagemin/gifsicle-bin package with 343dev/gifsicle.
• Added new configuration parameters in .optimiztrc.cjs:
  • optimize.gif.lossy.gamma
  • optimize.gif.lossless.gamma
• Updated gifsicle to version 1.96.

Benefits

• Reduced Dependencies: Total project dependencies decreased from 218 to 41.
• Improved Platform Support: Added arm64 binary versions for guetzli and gifsicle.

Important Note About Gamma Parameters

The new gamma parameters were added because of changes in gifsicle 1.96. In this version:

• The --lossy option now measures color errors using the color space selected by --gamma (defaults to sRGB).
• A new algorithm for computing color differences has been implemented.
• This means --lossy=N will behave differently than in previous versions and may compress less than expected.
• For behavior similar to previous versions, use --lossy=N --gamma=1.

Migration Guide

If you use an external configuration file (.optimiztrc.cjs), add the following parameters with a value of 1 to preserve the previous behavior:

• optimize.gif.lossy.gamma
• optimize.gif.lossless.gamma
