Version: 0.9.7
Date: 2021-05-07

	Features:
		-Updated wall and gate graphics/icons (Re-colored vanilla images)
		-Hybrid walls will not connect/merge with vanilla walls. (I had initially set them to connect/merge, but the effect was not consistent)

Date: 2021-05-07

	Features:
		-Updated to Factorio 1.1
	
	Bugfix:
		-Updated tech requirement references to reflect name changes in vanilla.

Version: 0.9.5
Date: 2020-08-18

	Features:
		-Added 2 more tiers of wall/gate plus required research
		-Changed bonus biomass from a flat bonus (base + integer) to an actual scale (base + (scale * tier)). This should allow players to change the drop rate more to their liking.
		-Adjusted required research unlocks and packs to make a bit more sense. Also adjusted research costs. This should force unlocks to be later in the game. These walls were never meant to be impenetrable.
