Yazsoft today announced the release of Speed Download 2.3.3, a new version of its download manager for Mac OS X. “This is a very important update and is highly recommended because it reflects directly on the decision to strip SD completely of MacShareware.net and to focus solely on continuously perfecting the download manager,” Yazsoft said. The company had recently run into problems with both VersionTracker and MacUpdate not posting SD updates because of its move towards becoming a software update application that competed with offerings from these sites. Version 2.3.3 also includes an updated and optimized SD plug-in for better compatibility, as well as support for downloading files over 1GB in size. Speed Download sells for US$20.
