  • v10.3.2 Changes

    October 29, 2020

    🚀 Tiny tiny release, just to fix the website incorrectly not listing Javascript
    🏗 in the list of languages you could choose for a custom build. NPM and CDN
    🏗 build should not have been affected so 10.3.1 is effectively the same as
    🏗 10.3.2 for those builds.

    🏗 If you made a custom build from the website with 10.3 or 10.3.1 you may
    🏗 want to check and make sure it includes Javascript, and if not, build it again.
