On October 26, 2012, Logos will drop support for Windows XP and OS X 10.5 “Leopard.”
Your existing Logos 4 installs will continue to run, but future releases of Logos Bible Software will require Windows Vista SP2 or newer.
This will not disable any XP systems, but future book releases may use new features or data types only available in newer versions of Logos, and therefore, may not be usable on Windows XP systems.
Logos 4 depends on a number of Microsoft platform components, including the .NET framework. With the October 26, 2012, release of Windows 8, Microsoft is upgrading the .NET 4 platform to .NET 4.5, which is an “in-place” install replacing .NET 4 (which we’re planning to move to for many reasons, including performance and bug fixes).
.NET 4.5 will run on Windows Vista SP2 and later versions of Windows, but specifically NOT Windows XP.
Very few Logos users remain on XP, and continuing to support XP in new releases takes development and testing resources, and makes it more difficult to use other capabilities only offered on newer versions of Windows.
OS X 10.5 “Leopard”
Your existing install will continue to run, but future releases of Logos Bible Software will require newer versions of OS X.
This will not disable your system, but future releases may use new features or data types only available in newer versions of Logos, and thus will not be usable on OS X 10.5.
We have even fewer users on OS X 10.5 than on XP. And coincidentally OS X 10.5 “Leopard” was released on October 26, 2007, meaning that it will be five years since its release and it is now three major releases out of date. Dropping 10.5 support in future releases will free up development and testing resources and allow us to do more.
