   * [querier] added custom querier functionality, so ABCI query requests can be handled by keepers
   * [simulation] [\#1924](https://github.com/cosmos/cosmos-sdk/issues/1924) allow operations to specify future operations
   * [simulation] [\#1924](https://github.com/cosmos/cosmos-sdk/issues/1924) Add benchmarking capabilities, with makefile commands "test_sim_gaia_benchmark, test_sim_gaia_profile"
+  * [simulation] [\#2349](https://github.com/cosmos/cosmos-sdk/issues/2349) Add time-based future scheduled operations to simulator
