Dev Builds are unstable build released for testing purposes. Dev builds have
DEV BUILD or
BETA in the title.
Do NOT overwrite your existing jEveAssets directory with the dev build files
Unless otherwise noted all dev build have the dev build flag enabled. When the dev build flag is enabled jEveAssets will create a sandbox of you data to keep it safe. This is done by copying the data to the program directory and running portable. That means jEveAssets need to have write permission to program directory. Dev build also have all program and static data update functionality disabled.
