v6.6.0

Release Notes

The Release Procedure is defined in the CONTRIBUTING document.

v6.6.0

Highlights:

• Cosmos SDK v0.47.13 update.
• Adding new auction module to our app.
• Removing crisis module from our app.

Auction module

We propose a new Cosmos SDK module, that will provide mechanism for protocol owned auctions. UX Chain will now auction a portion of collected fees and introduce a token burning mechanism, unlocking a way to a potentially deflationary UX token.
Documentation: x/auction/README.md

Validators

Upgrade Title (for Cosmovisor): v6.6

Update Price Feeder to umee/2.4.3+.

NOTE: after the upgrade, you should restart your Price Feeder. We observed that Price Feeder doesn't correctly re-establish a connection after the chain upgrade.

libwasmvm update

Our dependencies have been updated. The binary requires libwasmvm v1.5.2. When you build the binary from source on the server machine you probably don't need any change. However, when you download a binary from GitHub, or from another source, make sure you update the /usr/lib/libwasmvm.<cpu_arch>.so. For example:

• copy from $GOPATH/pkg/mod/github.com/!cosm!wasm/[email protected]/internal/api/libwasmvm.$(uname -m).so
• or download from github wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.5.2/internal/api/libwasmvm.$(uname -m).so -O /lib/libwasmvm.$(uname -m).so

You don't need to do anything if you are using our Docker image.

Upgrade instructions

• Download latest binary or build from source.
• Make sure libwasmvm.$(uname -m).so is properly linked
  • Run the binary to make sure it works for you: umeed version
• Wait for software upgrade proposal to pass and trigger the chain upgrade.
• Swap binaries.
• Ensure latest Price Feeder (see compatibility matrix) is running and ensure your price feeder configuration is up-to-date.
• Restart the chain.
• Restart Price Feeder.

You can use Cosmovisor → see instructions.

Docker images are available in ghcr.io umee-network repository.

v6.4.1

Release Notes

The Release Procedure is defined in the CONTRIBUTING document.

v6.4.1

This release updates our dependencies and applies latest patches to the v6.4.x line. All validators must update to this patch release.

Docker

Docker images are available in ghcr.io umee-network repository.

v6.4.0

Release Notes

The Release Procedure is defined in the CONTRIBUTING document.

v6.4.0

Highlights:

• Cosmos SDK v0.47.10 patch update.
• IBC Hooks: we integrated ICS20 Memo handling.
• Integrated Packet Forwarding Middleware.
• Update uibc/MsgGovUpdateQuota Msg type to handle the new inflow parameters.
• Update uibc/QueryAllOutflowsResponse to include denom symbol (token name) in every outflow.

CHANGELOG

IBC Hooks

This release brings the first part of the seamless cross-chain money market transactions. At UX, we want to provide the best User Experience for handling lending and leverage. In this release, we support the following x/leverage messages:

• MsgSupply
• MsgSupplyCollateral
• MsgLiquidate

The operation can only use tokens that are part of the IBC transfer (after any intermediate deductions) and the supplier / liquidator must be the IBC recipient (acting on someone else's behalf is not allowed). Authz is not supported. The remaining tokens will be credited to the recipient.

v6.2.0

Release Notes

Release Procedure is defined in the CONTRIBUTING document.

v6.2.0

Highlights:

• Umee chain upgrades to the latest stable Cosmos SDK v0.47
• The gov module in in Cosmos SDK v0.47 has been updated to support a minimum proposal deposit at submission time. It is determined by a new parameter called MinInitialDepositRatio. When multiplied by the existing MinDeposit parameter, it produces the necessary proportion of coins needed at the proposal submission time. The motivation for this change is to prevent proposal spamming.
  We set MinInitialDepositRatio to 10%.`
• Added meToken WASM queries.
• IBC Quota v2 mechanism
  1. Outflows quota has been increased to $1.6M for total outflows and $1.2M per token outflows.
  2. new lifting conditions is added: IBC outflows are possible if (1.) fails, but
     • sum outflows of all tokens <= $1M + InflowOutflowQuotaRate * sum_of_all_inflows;
     • and token outflows <= $0.9M + InflowOutflowQuotaRate * token_inflows.
       See IBC Quota Design for more details.

Upgrade Title (for Cosmovisor): v6.2.

Price Feeder

Price Feeder < umee/v2.3.0 is not compatible with Cosmos SDK v0.47. Validators must update to umee/v2.3.0 or newer.

During the testnet upgrade, we noticed miss counters increasing dramatically. Please make sure your transactions are going through. If you see out of gas in your transactions (example), please increase gas_adjustment to 2.0 in your price-feeder.toml.

We recommend to actively track your miss counters and making sure you follow the latest currency-pairs config (note the umee branch).

libwasmvm update

Our dependencies have been updated. Now the binary requires libwasmvm v1.5.0. When you build the binary from source on the server machine you probably don't need any change. However when you download a binary from GitHub, or from other source, make sure you update the /usr/lib/libwasmvm.<cpu_arch>.so. For example:

• copy from $GOPATH/pkg/mod/github.com/!cosm!wasm/[email protected]/internal/api/libwasmvm.$(uname -m).so
• or download from github wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.5.0/internal/api/libwasmvm.$(uname -m).so -O /lib/libwasmvm.$(uname -m).so
