|
|
// v2 added named files via a[download], msSaveBlob, IE (10+) support, and window.URL support for larger+faster saves than dataURLs
|

// v3 added dataURL and Blob Input, bind-toggle arity, and legacy dataURL fallback was improved with force-download mime and base64 support. 3.1 improved safari handling.
|
|
// v4 adds AMD/UMD, commonJS, and plain browser support
|
|
// v4.1 adds url download capability via solo URL argument (same domain/CORS only)
|
|
// v4.2 adds semantic variable names, long (over 2MB) dataURL support, and hidden by default temp anchors
