Cosmos SDK v0.42.6 "Stargate" Release Notes

This release includes various minor bugfixes and improvments, including:

• x/bank's InitGenesis optimization, which should significantly decrease genesis initialization time,
• bump Tendermint to v0.34.11 to fix state sync issues,
• add cosmos_sdk_version to node_info to be able to query the SDK version used by a node,
• IBC bugfixes and improvements (see below for more info),
• new fields on sdk.Context (see below for more info).

See the Cosmos SDK v0.42.6 milestone on our issue tracker for the exhaustive list of all changes.

IBC Bugfixes and Improvements

The [appd] query ibc client header is fixed and allows querying by height for the header and node-state command. This allows easier venerability of which IBC tokens belong to which chains. IBC's ExportGenesis now exports all fields, including previously missing NextClientSequence, NextConnectionSequence and NextChannelSequence. A new subcommand [appd] query ibc-transfer escrow-address has been added to get the escrow address for a channel; it can be used to then query balance of escrowed tokens.

New Fields on sdk.Context

Two fields have been added on sdk.Context:

• ctx.HeaderHash adds the current block header hash obtained during abci.RequestBeginBlock to the Context,
• ctx.GasMeter().RefundGas(<amount>, <description>) adds support for refunding gas directly to the gas meter.
