BREAKING CHANGES

* Gaia REST API (`gaiacli advanced rest-server`)
  * [gaia-lite] [\#2182] Renamed and merged all redelegations endpoints into `/stake/redelegations`

* Gaia CLI  (`gaiacli`)
  * [\#810](https://github.com/cosmos/cosmos-sdk/issues/810) Don't fallback to any default values for chain ID.
    * Users need to supply chain ID either via config file or the `--chain-id` flag.
    * Change `chain_id` and `trust_node` in `gaiacli` configuration to `chain-id` and `trust-node` respectively.
  * [\#3069](https://github.com/cosmos/cosmos-sdk/pull/3069) `--fee` flag renamed to `--fees` to support multiple coins
  * [\#3156](https://github.com/cosmos/cosmos-sdk/pull/3156) Remove unimplemented `gaiacli init` command

* Gaia
  * https://github.com/cosmos/cosmos-sdk/issues/2838 - Move store keys to constants
  * [\#3162](https://github.com/cosmos/cosmos-sdk/issues/3162) The `--gas` flag now takes `auto` instead of `simulate`
    in order to trigger a simulation of the tx before the actual execution.

* SDK
  * [\#3064](https://github.com/cosmos/cosmos-sdk/issues/3064) Sanitize `sdk.Coin` denom. Coins denoms are now case insensitive, i.e. 100fooToken equals to 100FOOTOKEN.
  * \#3207 - Fix token printing bug

* Tendermint
