 * (x/params) [\#5619](https://github.com/cosmos/cosmos-sdk/pull/5619) The `x/params` keeper now accepts a `codec.Marshaller` instead of
 a reference to an amino codec. Amino is still used for JSON serialization.

 ### Bug Fixes
 
+* (baseapp) [\#5718](https://github.com/cosmos/cosmos-sdk/pull/5718) Remove call to `ctx.BlockGasMeter` during failed message validation which

 * (client) [\#5618](https://github.com/cosmos/cosmos-sdk/pull/5618) Fix crash on the client when the verifier is not set.

 * (genesis) [\#5086](https://github.com/cosmos/cosmos-sdk/issues/5086) Ensure `gentxs` are always an empty array instead of `nil`

@@ -56,6 +56,33 @@ During each `EndBlock` execution, the `x/upgrade` module checks if there exists
 `Handler` is executed. If the `Plan` is expected to execute but no `Handler` is registered
 or if the binary was upgraded too early, the node will gracefully panic and exit.
 
+## StoreLoader
+
+
+The `x/upgrade` module also facilitates store migrations as part of the upgrade. The
+`StoreLoader` sets the migrations that need to occur before the new binary can 
+successfully run the chain. This `StoreLoader` is also application specific and 
+not defined on a per-module basis. Registering this `StoreLoader` is done via
+`app#SetStoreLoader` in the application.
+
+```go
+func UpgradeStoreLoader (upgradeHeight int64, storeUpgrades *store.StoreUpgrades) baseapp.StoreLoader
+```
+
+If there's a planned upgrade and the upgrade height is reached, the old binary writes `UpgradeInfo` to the disk before panic'ing.
+
+```go
+type UpgradeInfo struct {
+  Name    string
+  Height  int64
+}
+```
+
+This information is critical to ensure the `StoreUpgrades` happens smoothly at correct height and
+expected upgrade. It eliminiates the chances for the new binary to execute `StoreUpgrades` multiple
+times everytime on restart. Also if there are multiple upgrades planned on same height, the `Name`
+will ensure these `StoreUpgrades` takes place only in planned upgrade handler.
+
 ## Proposal
 
 Typically, a `Plan` is proposed and submitted through governance via a `SoftwareUpgradeProposal`.
