This is DotNetZip v1.9. It is the latest stable release. The current version number is v18.104.22.168, released 2010 February 25.
New features:Parallel deflate, to optimize the Zip library to use multi-processorsSupport Asynchronous Operationscreate and read multi-part zip files.Allow setters on ModifiedTime, AccessedTime, CreationTimeMake traversal of NTFS Junctions optional in AddDirectoryExpose IsZipFile method to COM clientsAdd support for optionally traversing directory junctions in WinForms appAllow writing into ZipEntry stream (WriteDelegate)implement ZipOutputStreamImplement a ZipInputStreamSelf Extracting EXE - optionally remove files after running "post unpack exe"Environment Variable substitution on the default extract location of SFXDeliver DotNetZipLib Help so that it can be integrated into VS2008
Notable fixes: Zip Tool and File associationsRemove obsolete methods and propertiesCan't unzip on the Mac, when the zip was written to Response.OutputStream and includes a folderZlib exception when compressed stream size is (multiple of buffer size) + header size +(0 to 7)Public key token differs between ILMerge'd DLLs and regular DLLs
There are some breaking changes from v1.8:
- the SaveSelfExtractor() methods have been consolidated. They use the new SelfExtractorSaveOptions class.
- All the interfaces marked Obsolete in v1.8 have been removed. These include: the methods on the ZipFile class: AddFileFromStream(), AddFileStream() UpdateFileStream(), AddFileFromString(), all the Extract() methods that accept an entry name, and the ExtractAll() method that accepts a boolean; on the ZipEntry class, the Extract() methods that accept a Boolean, and the OverwriteOnExtract property, as well as the SetNtfsTimes() method.
- For FxCopy compliance, the properties on the ZipEntry called Atime, Mtime, and Ctime have been replaced with AccessedTime, ModifiedTime and CreationTime.
- The WantCompression callback has been removed. There is a SetCompression callback that can be used in its place.
- The ReadTwiceOnInflation callback has been removed. It's no longer necessary now that DotNetZip uses zlib.
- The ForceNoCompression property has been removed as redundant. Use CompressionLevel instead.
- The public key used on some of the assemblies has changed. (See workitem 8819)
- The ZipFile.AddEntry and UpdateEntry methods that accept a directoryPathInArchive have been modified.
Features being deferred to the next release
- Asynchronous Programming Model for DeflateStream/GZipStream/ZlibStream
- Silverlight support
- expanded COM support: events, zlib, etc.
There will also be fit-and-finish changes and bug fixes. I would also expect a few smaller, tactical features.
This release has these downloads:
- DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities.
- DotNetZipLib-DevKit-v1.9.zip - a binary release, that includes of the signed DLLs for Zip and Zlib, for desktop and Compact Framework; the XML Documentation file for intellisense; the compiled help file (CHM); and the License. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library.
- DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the License. Download this if you want to distribute .NET applications that use the Zip library, or if you want to run a .NET application that depends on this library.
- DotNetZipLib-Runtime-v1.9.msi - Same as the Runtime zip above, packaged in an MSI installer. It registers the DLL for COM use. Download this if you want to install DotNetZip on a computer that will run apps that depend on the library.
- DotNetZipUtils-v1.9.zip - a set of exe tools (command-line and GUI) that rely on the library, to create and manage zip files. Download this if you want tools to manipulate zip files.
- DotNetZipUtils-v1.9.msi - an installer for Windows for the Zip utilities that utilize the library. This is the same stuff as the DotNetZipUtils-v1.9.zip, but in MSI form. It optionally sets up file associations, guides you through the install.
- DotNetZipLib-v1.9.chm - the help file. See the FAQ item on the home page for how to enable this file for reading.
