Download the New Version of Compressor

Gzip, the author of the compression FAQ list and original author of Zip, has made significant updates to its compression routines. The latest version of zlib is now available for download, offering improved performance and functionality.

One of the key benefits of the new version is its ability to double or triple file size in extreme cases, making it an ideal solution for compressing large files. Additionally, the memory footprint of zlib can be reduced if necessary, at some cost in compression speed.

Unlike other compression methods, such as LZW used in Unix compress and GIF image format, zlib's compression method never expands the data, ensuring that your files remain compact and efficient.

The zlib data format is also portable across various computer hardware and operating systems, making it a versatile solution for use on any platform. And with its legally unencumbered status - not covered by any patents - you can rest assured that your compressed files are protected by open-source licensing.

In this latest version, several bugs have been fixed to improve overall performance and reliability. These include:

* Fix inflateBack to detect invalid input with distances too far

* Repair prototypes and exporting of new CRC functions

* Correct incorrect inputs provided to the CRC functions

* Fix a configure issue that discarded the provided CC definition

* Now the smallest block type is selected for better compression

* Fix a bug in block type selection when Z_FIXED used

* Fix a bug when getting a gzip header extra field with inflateGetHeader()

These updates are significant, especially for users who rely on zlib's minizip library. The latest version includes fixes for several issues, including:

* Fixed a logic error in minizip argument processing

* Fixed reading disk number start on zip64 files in minizip

* Fixed minizip to allow it to open an empty zip file

* Fixed test/example.c to work with FORCE_STORED

Overall, the new version of zlib offers improved compression performance and reliability, making it a valuable tool for any developer or user working with compressed data. Download the latest version today and experience the benefits of Gzip's cutting-edge compression technology!
