v6.0.0 tracking issue

[crodriguezvega]

This release's main addition is the ICA improvements.

These improvements tackle two shortcomings of the current implementation of ICS-27:

• The lack of a default/standard underlying app (also known as authentication module), which created a bottleneck for chains looking to integrate the controller submodule.
• The need to separate application and authentication concerns.

The changes will make integrating the controller chain functionality easier (see ADR 009 for more information), and with the release of Cosmos SDK v0.46.x, they will enable any Cosmos SDK module (e.g x/auth, x/gov, x/group) to register interchain accounts and send transactions on their behalf.

For more details about these changes, please read this blog post.

Other features/improvements:

• ICS-20:

  • Adding a metadata field in FungibleTokenPacketData (implementation of Add metadata field to transfer packet data ibc#842 spec - update).
  • Adding the sequence number of the packet sent to MsgTransferResponse.

• 04-channel:

  • Simplify SendPacket API (implementation of ICS4: Simplify sendPacket interface ibc#731 spec update).
