Release Notes

mapbox/pixelmatch (pixelmatch)

v7.1.0

Compare Source

• Add first-class TypeScript types to the project. They'll be maintained in the repo from now on. #​139
• Improve matching performance by ~22%. #​150

v7.0.0

Compare Source

• Potentially breaking: improve handling of semitransparent pixels. Previously, they were blended with white, so a transparent pixel vs white pixel would show zero difference; now pixels are blended with an irregular pattern, making it easier to catch regressions. (h/t @​NathanMOlson #​142)
• Improve match performance by ~6%. #​147
• Significantly improve diff generation performance. (h/t @​kawanet #​105)
• Fix options handling to use the default value when undefined is passed explicitly. (h/t @​denis-sokolov #​146)
• Fix ESLint failing on Windows when working on the library locally. (h/t @​haraldreingruber-dedalus #​123)

v6.0.0

⚠️ Breaking: publish pixelmatch as a ES module. Use the older v5.3.0 if you need to support CommonJS environments.
