 # Lotus changelog
 
+# 0.6.0 / 2020-09-07
+
+This consensus-breaking release of Lotus is designed to test a network upgrade on the space race testnet. The changes that break consensus are:
+
+- Tweaking of some cryptoecon parameters in specs-actors 0.9.7 (https://github.com/filecoin-project/specs-actors/releases/tag/v0.9.7)
+- Rebalancing FIL distribution to make testnet FIL scarce, which prevents base fee spikes and sets better expectations for mainnet
+
+This release also introduces many improvements to Lotus! Among them are a new version of go-fil-markets that supports non-blocking retrieval, various spam reduction measures in the messagepool and p2p logic, and UX improvements to payment channels, dealmaking, and state inspection.
+
