+## Linear Leios
+- Allow RBs to include EB certificates produced at least `L_diff` slots ago, instead of `L_vote + L_diff` slots ago. When `L_diff` is 0, this removes any direct time factor from the decision to include an EB cert.

+# v0.1.0
+
+This version was arbitrarily chosen as the point to start tracking major changes to the simulation.
