silEnT servers support Lua 5.1.4 scripts up till version 0.8.2.
Since version 0.9.0 silEnT mod supports Lua 5.3.1 compiled to be compatible with Lua version 5.2.
Starting from version 0.5.1 the Lua interpreter is inbuilt into the server side mod. Before the vesion 0.5.1, the Lua was installed as an external module. A separate build of the silEnT mod is supplied within the download to admins who still want to use separate Lua library. silEnT's Lua API is aiming to be fully compatible to ETPro's Lua API. The origin of the silEnT Lua API is the Lua module in ETPub version 0.9.1.
