### 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.
```js
// 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 :
```js
// 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();
```
