Canto announced the immediate availability of Cumulus 7.5.3, a minor update that improves the performance and reliability of the entire Cumulus product line. The company says that Cumulus 7.5.3 is running on the recently released Service Pack 1 for Windows Vista, and OS X Leopard performance and reliability continues to be stable since the release of version 7.5.2, though a handful of improvements have been made to support Apple’s latest OS even better. Canto recommends all customers upgrade to Cumulus 7.5.3, regardless of operating system, to benefit from global fixes and improvements. Customers on active service agreements can download the update free of charge from Canto’s Customer Portal. The Cumulus product line was last updated in December, 2007, with the release of Cumulus 7.5.2. http:/
