# 3.1.2 (2017-11-17)
4+
- Changed the algorithm for adding paddings to zipalign.
5+
Now we will use the special field ExtraField c ID 0xD935,
6+
which was implemented by Google in the apksigner library.
7+
Now this field corresponds to the ZIP standard for storing
8+
ExtraField records, and not just filling with zero bytes,
9+
as in the zipalign console utility.
10+
11+
## 3.1.1 (2017-11-15)
12+
- Fix resave zip aligned archive
13+
314
## 3.1.0 (2017-11-14)
415
- Added class `ZipModel` for all changes.
516
- All manipulations with incoming and outgoing streams are in separate files: `ZipInputStream` and `ZipOutputStream`.
