Upgrade Guide	default	main

From 2.2.2 to 2.3.0

• On ZipObject#options, the attributes date and dir have been deprecated and are now on ZipObject.
• On ZipObject#options, the attributes base64 and binary have been deprecated.
• JSZip.base64, JSZip.prototype.crc32, JSZip.prototype.utf8decode, JSZip.prototype.utf8encode and JSZip.utils have been deprecated.

// deprecated
zip.file("test.txt").options.date
zip.file("test.txt").options.dir
// new API
zip.file("test.txt").date
zip.file("test.txt").dir

From 2.0.0 to 2.1.0

• The packaging changed : instead of loading jszip.js, jszip-load.js, jszip-inflate.js, jszip-deflate.js, just include dist/jszip.js or dist/jszip.min.js. For AMD loader users : JSZip now registers itself. You just have to put the file at the right place or configure your loader.

From 1.x to 2.x

• JSZipBase64 has been renamed to JSZip.base64.
• The data attribute doesn't exist anymore : use the getters asText(), asBinary(), etc
• The compression/decompression methods now give their input type with the compressInputType and uncompressInputType attributes.

Example for the data attribute :

// before
zip.file("test.txt").data;
zip.files["test.txt"].data;
zip.file("image.png").data;
zip.files["image.png"].data;

// after
zip.file("test.txt").asText();
zip.files["test.txt"].asText();
zip.file("image.png").asBinary();
zip.files["image.png"].asBinary();
