The latest versions include the following improvements over *Legacy

- Fixed bug where duplicate zones and surfaces were being created
- Updated for *EnergyPlus 8.6* and *8.7*
- Fixed error notification feature
- And other miscellaneous bug fixes.
One caveat on the update for *EnergyPlus 8.6*: The Daylighting:Controls
object has changed in 8.6 and is not yet handled correctly. We expect to
have a fix for this in an upcoming version. In the meantime the
Daylighting:Controls tool and rendering has been temporarily disabled. Any
daylighting sensors in your existing models will not be displayed, nor will
they be deleted or modified.
If you have any problems with the *Euclid* extension, please let us know!
