Beta 6 is almost done, ironing out the last bugs. I've ported 80% of the deity system from Incursion and the total line count has exceeded 50k lines.
I suppose a test version will be released first on te4.org to catch any lingering bugs and then BETA 6 will come here! Headway has been made concerning ancient bugs (some dating back to 2013) and engine bugs, but I am making no promises that beta 6 will be absolutely bug-free.
At any rate, Beta 6 is to arrive before 1 Oct!
