* Start upgrade. Currently go test ./... hangs. * (squash this) Fix staking tests * wip * note what changes need to be made to make this work on tm v0.23.0 * Fix addr -> pubkey map * cleanup code * Fix slashing test failures except for begin blocker * fix all slashing tests * fix lcd tests * Address PR comments * add link to changelog. * (wip) start making addrToPubkey map persisted. Since amino can't handle maps, we have to change from what this commit is doing. * Use the correct method of storing a map * (squash this) address PR comments * Did you run 'make'? * remove gaiadebug binary
