MapLibre GL JS v0.54.0 Release Notes

  • 💥 Breaking changes

    • 🐎 Turned localIdeographFontFamily map option on by default. This may change how CJK labels are rendered, but dramatically improves performance of CJK maps (because the browser no longer needs to download heavy amounts of font data from the server). Add localIdeographFontFamily: false to turn this off. #8008
    • ➕ Added Popup maxWidth option, set to "240px" by default. #7906

    Major features

    • ➕ Added support for updating and animating style images. #7999
    • ➕ Added support for generating style images dynamically (e.g. for drawing icons based on feature properties). #7987
    • ➕ Added antialiasing support for custom layers. #7821
    • ➕ Added a new mapbox-gl-csp.js bundle for strict CSP environments where worker-src: blob is disallowed. #8044
