Cheeso — Sun, 07 Aug 2011 08:31:20 GMT

This is the latest stable release of DotNetZip.

Status: The binaries here are final. All of the bugs listed here are new fixes in these binaries, since v1.9.1.5.

This release has these downloads:

DotNetZipLib-DevKit-v1.9.zip - This is probably what you want. This is 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 help files (CHM & Helpviewer); and the Licenses. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library.
DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, the test code, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities.
DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the Licenses. Download this if you want to distribute .NET applications that use the Zip library, on the desktop or on the Compact Framework, or if you want to run a .NET application that depends on this library.
DotNetZipLib-Silverlight-v1.9.zip - a binary release, that includes the the Silverlight version of the signed DLLs, and the Licenses.
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 finished user-level tools to manipulate zip files. (A replacement for WinZip)
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.
DotNetZip-Runtime-v1.9.msi - an installer for the runtime.
DotNetZip-Documentation-v1.9.zip - the Documentation. There's a CHM file as well as a HelpViewer 1.0 format. They contain the same information, just in different formats.

Notable:

the quality/reliability of the code is much higher than for v1.9.1.5 - many bug fixes.
New bzip2.exe tool, and a gzip.exe tool.
Silverlight DLLs for ZIP, ZLIB or BZIP2 are included
more than 60 new tests
The version numbers for these preliminary DLLs is currently v1.9.1.8

The minimum requirement for the binaries is (as in prior releases of DotNetZip) .NET 2.0 or later. To build the source you need VS2010 and .NET 4.0.

Released: v1.9.1.6 DotNetZip - Latest Stable (Jul 11, 2011)

Wed, 03 Aug 2011 17:37:17 GMT

This is the latest stable release of DotNetZip.

Status: The binaries here are final. All of the bugs listed here are fixed in these binaries.

This release has these downloads:

DotNetZipLib-DevKit-v1.9.zip - This is probably what you want. This is 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 help files (CHM & Helpviewer); and the Licenses. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library.
DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, the test code, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities.
DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the Licenses. Download this if you want to distribute .NET applications that use the Zip library, on the desktop or on the Compact Framework, or if you want to run a .NET application that depends on this library.
DotNetZipLib-Silverlight-v1.9.zip - a binary release, that includes the the Silverlight version of the signed DLLs, and the Licenses.
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 finished user-level tools to manipulate zip files. (A replacement for WinZip)
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.
DotNetZip-Runtime-v1.9.msi - an installer for the runtime.
DotNetZip-Documentation-v1.9.zip - the Documentation. There's a CHM file as well as a HelpViewer 1.0 format. They contain the same information, just in different formats.

Notable:

Updated Release: 1.9.1.5 DotNetZip (Aug 28, 2009)

Cheeso — Wed, 03 Aug 2011 07:42:36 GMT

This is DotNetZip v1.9. It is the latest stable release. The current version number is v1.9.1.5, released 2010 February 25.

New features:
Parallel deflate, to optimize the Zip library to use multi-processors
Support Asynchronous Operations
create and read multi-part zip files.
Allow setters on ModifiedTime, AccessedTime, CreationTime
Make traversal of NTFS Junctions optional in AddDirectory
Expose IsZipFile method to COM clients
Add support for optionally traversing directory junctions in WinForms app
Allow writing into ZipEntry stream (WriteDelegate)
implement ZipOutputStream
Implement a ZipInputStream
Self Extracting EXE - optionally remove files after running "post unpack exe"
Environment Variable substitution on the default extract location of SFX
Deliver DotNetZipLib Help so that it can be integrated into VS2008

Notable fixes:
Zip Tool and File associations
Remove obsolete methods and properties
Can't unzip on the Mac, when the zip was written to Response.OutputStream and includes a folder
Zlib 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.

"File already exists" error when adding new file to a zip file
Exception when creating split archive
ZipOutputStream corrupts data buffer when calling Write(byte[],int,int)
Trying to zip the root zips the current working directory instead

NullRereferenceException when extracting
Array out of bounds exception in finish()
doc for ZipEntry.IsText property should be clearer and more complete
Errors with Duplicate Entries
Select does not work with forward slashes
Possible bug in ZlibStream
FileNotFoundException when creating a Self Extracting Zip file
Malformed zip file should throw ZipException or BadReadException, not IOException
Ensure consistency on exceptions on ZipFile.Read() failure.

BOM in file contrary to the behavior described by the documentation
Writing zero bytes to a ZipOutputStream causes exception
Incorrect decoding of the comment in ZipFile.Read() method.
Fix the use of Exceptions in PDOS
Include the License for ZLIB in the binary distributions
Writing zero bytes to a ZipOutputStream causes exception
String Indexer on ZipFile fails to find the entry by name
Tools/WinFormApp does not correctly create split archives

File not found when compressing zipped file into spanned archive
Can't delete .z01 file after extraction of multi-segment archive
Splitting Large (~1gb+) files leads to an exception
extracting zip with several segments, cannot delete .zip file afterwards
Creating a split archive does not close intermediate streams
Allow a way to specify upper limit of # threads used for compressing
Bug when compressing .rar or .zip file

Add a CheckZipPassword static method to ZipFile class
expose CountingStream as a public type
creating an SFX should allow an option to set the title of the extractor window
Cannot cancel within AddProgress event
Provide a way to Force UTF-8 (or whatever the alternate encoding is) in filenames

new source features:
Upgrade the source to VS2010
Add InfoZip compatibility tests to the test source

Updated Release: v1.9.1.6 - maintenance and bugfix (beta) (Jul 11, 2011)

Cheeso — Wed, 03 Aug 2011 00:25:24 GMT

This is a bugfix release for v1.9.

Status: The binaries here are near final. All of the bugs listed here are fixed in these binaries. I've run the test suite and everything passes.

This release has these downloads:

DotNetZipLib-DevKit-v1.9.zip - This is probably what you want. This is 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 help files (CHM & Helpviewer); and the Licenses. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library.
DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, the test code, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities.
DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the Licenses. Download this if you want to distribute .NET applications that use the Zip library, on the desktop or on the Compact Framework, or if you want to run a .NET application that depends on this library.
DotNetZipLib-Silverlight-v1.9.zip - a binary release, that includes the the Silverlight version of the signed DLLs, and the Licenses.
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 finished user-level tools to manipulate zip files. (A replacement for WinZip)
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.
DotNetZip-Runtime-v1.9.msi - an installer for the runtime.
DotNetZip-Documentation-v1.9.zip - the Documentation. There's a CHM file as well as a HelpViewer 1.0 format. They contain the same information, just in different formats.

Notable:

the quality/reliability of the code is much higher than for v1.9.1.5 - many bug fixes.
New bzip2.exe tool, and a gzip.exe tool.
Silverlight DLLs for ZIP, ZLIB or BZIP2 are included
The helpfile still needs work
The version numbers for these preliminary DLLs is currently v1.9.1.6006

The minimum requirement for the binaries is (as in prior releases of DotNetZip) .NET 2.0 or later. To build the source you need VS2010 and .NET 4.0.

Try it out and give me feedback. But make it fast: I hope to get the final v1.9.1.6 out very soon.
