* [\#3176](https://github.com/cosmos/cosmos-sdk/issues/3176) `tx/sign` endpoint now expects `BaseReq` fields as nested object.
* SDK
* [stake] \#2513 Validator power type from Dec -> Int
* [stake] \#2513 Validator power type from Dec -> Int
* [stake] \#3233 key and value now contain duplicate fields to simplify code
* [\#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.

* Gaia CLI (`gaiacli`)
* \#3141 Fix the bug in GetAccount when `len(res) == 0` and `err == nil`
* Gaia
* \#3148 Fix `gaiad export` by adding a boolean to `NewGaiaApp` determining whether or not to load the latest version
* \#3181 Correctly reset total accum update height and jailed-validator bond height / unbonding height on export-for-zero-height
* [\#3172](https://github.com/cosmos/cosmos-sdk/pull/3172) Fix parsing `gaiad.toml`
when it already exists.
* \#3223 Fix unset governance proposal queues when importing state from old chain
* [#3187](https://github.com/cosmos/cosmos-sdk/issues/3187) Fix `gaiad export`
by resetting each validator's slashing period.
