EnergyPlus 8.5.0
Windows packages for EnergyPlus 8.6.0 and prior had a vulnerability in the View3D binary that could expose users to a stack-based buffer overflow. Because of this, all Windows packages 8.6.0 and older have been purged and are no longer available. We apologize for any inconvenience.

For more information about EnergyPlus, please visit www.energyplus.net.
Interface Note
As with every EnergyPlus, older versions of EnergyPlus input files will not run directly with this version, and must be transitioned up to the latest version. EnergyPlus is packaged with transition utilities for updating the idfs automatically. There is also a Rules spreadsheet available in the installation to help interface developers program the transition. We are also tracking the structural changes to the outputs for EnergyPlus and including this documentation in the installer. For 8.5.0, the input rules changes file is here and the output rules changes file is here.
Documentation
The EnergyPlus documentation underwent a full transition from the Markdown/MathJax/HTML basis, to a full LaTeX implementation. This helped drastically streamline the development process and improve the developer's ability to test documentation changes, and also produced much improved pdf documentation over the last couple versions. The conversion was tested several times and confirmed to produce the same content as before to as best as we could tell. However, if you find any structural issues (pieces missing...), please post an issue on GitHub. We are going to be making our way through the entire set of documentation, cleaning up visual issues like alignment or long equations, so no need to post an issue for those visual things. We'll also be styling the documentation up to make it easy on the eyes.
