We have a zip file created with the ZipLibrary.
It is not possible to extract it with the "Compressed Folder Tools" tool from the "Windows Explorer" application, which is the default compress tool in Windows 8.
The result is an error saying that the zip file is invalid.

Video (wmv) and Audio (wav) files aren't properly compressed. The zip file that the library creates is larger than the original media file.

The exception occurs when files larger than 1 GB are being added to ZipPackage

In some cases the ZipArchive requires to use the Flush method for its stream. When the stream like the MS.Internal.InternalMemoryStream does not support it then it causes the NotSupportedException.

When you create a ZipPackage and then use the Add method to add a .dll file the created archive is corrupted.

Incorrect output when creating an archive from a json file (when the text in the file is too long).

When used to zip files which names contains special characters(such as swedish special characters) the filename is displayed with wrong encoding after unzipping the file.

The fix is available in our latest LIB release (v. 2015.1.0323).

When operation stream is created on top of the stream which doesn't support seeking the NullReferenceException is thrown from the constructor. There are other things which makes impossible using of the ZIP library on the stream which doesn't support seeking. We should fix these things.

When certain files are added to ZipPackage IndexOutOfRangeException is thrown.

Add additional properties to the ZipPackageEntry that describe the creation date, the last modified date and etc.

Add a possibility to create a ZipPackage with a password associated with it.

Ability to zip files bigger than 4 GB needed

Implement the "add file to existing archive" functionality

Currently, when setting a style to a table/table cell the following syntax is imported properly
.tdborder{border: 1px solid black}
However, if the order of the properties is changed (solid 1px black), the style will not be interpreted.

The fix will be available in our latest LIB release (v. 2015.1.0323).

When a document, which contains TOC with visible tab leader, is exported to PDF, the tab leader is missing in the produced document.

Add TableCell.TextDirection property.
