(WINNIPEG - December 15, 2009) - Indigo Rose Software today announced the launch of Visual Patch 3.5 with full support for Microsoft Windows 7. Visual Patch is a fast and efficient binary patch maker designed for software developers to create secure and compact software update patches. This new version creates compact binary difference patch files that can update multiple older versions of a software application to the current release, all from a single executable. Additionally, Visual Patch 3.5 is compatible with all versions of the Microsoft Windows operating systems from Windows 95 through Windows 7, making Visual Patch 3.5 a unique solution for software developers who require the widest compatibility for their software update patches. "The proprietary binary difference data compression algorithms found in Visual Patch 3.5 offer significant performance gains over older technology," said Colin Adams, president of Indigo Rose Software. "In our test suite, Visual Patch 3.5 was able to compress a 120 MB graphics file by 99.62 percent in only 9.05 seconds. In comparison, Microsoft"s MSP differencing algorithm required over 25 minutes to achieve a compression ratio of only 18.66 percent." Visual Patch 3.5 features advanced DeltaMAX (tm) binary difference data compression technology, providing impressive delta compression speed, even with gigabyte-sized files. Visual Patch"s full-history patching engine gives developers full control over which software versions can be patched with a single executable. For effortless software release management, Visual Patch integrates version management for a quick and easy way to add, remove and organize product versions, as well as to view all important file details. Visual Patch 3.5"s drag and drop development environment simplifies software version management, visually identifying which files have changed, and then calculating the exact byte-level differences within each file. The result is a compact and secure patch file that can synchronize any outdated version of a software application with the current version. Visual Patch curbs potential threats on applications and keeps data safe from unauthorized use and transmission errors using a combination of 128-bit hashing, checksums and industry standard data encryption protocols. Transmitting only tiny portions of a file in a format that is not able to be used without the original greatly reduces the risk of unauthorized use. Furthermore, Visual Patch has a powerful scripting engine with more than 250 high-level actions to give unprecedented control over the software patching system. Visual Patch 3.5 sells for $395 (US$) per developer or $995 for the Five Developer Team Pack. It can be purchased through all major software development tools resellers, or directly from Indigo Rose Software at http://www.indigorose.com/products/visual-patch/. A free 30-day trial download is available from the company"s website.
