6. Disabled LP Deposits into Highly Synth-Leveraged Pools (Prop 6)

As part of Prop 6 implementation, v3.4.0 saw nodes successfully vote to disable LP deposits into highly synth-leveraged pools. On 7-Apr, the relevant mimirs were set for six pools: BTC, ETH, DOGE, BCH, BNB and LTC.

Subsequently, on 10-Apr, BTC LP withdrawals were reenabled (these had been disabled since Feb due to a related bug, which was remedied by pausing LP deposits).

7. Reduce BTC Inbound Maximum Confirmation Blocks

On 13-Apr, nodes were invited to vote for reducing BTC inbound maximum confirmation blocks from three to two, for faster swaps. This vote was passed on 29-Apr.
