0.4.5: - Fixed river blocks not being rendered by shaders in recent versions of Forge/OptiFine. - Fixed river blocks not being rendered by BSL shaders (this works with 7.0 and 7.1.01, but not with earlier versions of 7.1). - Fixed river blocks ignoring biome-specific water colors when not using OptiFine.
0.4.6: - Fixed Streams river blocks disappearing from existing worlds when upgrading to Streams 0.4.5. (Note: upgrading from 0.4.5 to 0.4.6 will restore the missing blocks but will cause some of the sloping sections to misbehave. For best results, upgrade on the Forge-created world backup instead.)
