v5.2.0

Release Notes

Release Procedure is defined in the CONTRIBUTING document.

v5.2.0

This is a maintenance release, which prepares the chain for the v6.0 release.

Highlights:

• [x/leverage] Allow setting multiple tokens with the same symbol name but different denom. This fixes the oracle voting miss counter on duplicate symbol denoms.
• Adding Amino support to x/leverage.MsgLeveragedLiquidate.
• Fix MsgBeginUnbonding counting existing unbondings against max unbond twice.
• Fixes an x/oracle RPC endpoint spelling: /umee/oracle/v1/validators/{validator_addr}/aggregate_vote

More: v5.2.0 CHANGELOG.

Validators

Peggo

You can kill Peggo (there is no need to run it any more).

Min Gas Prices

Since v4.2 release we request all validators set a minimum-gas-prices setting (in app config/app.toml file, general settings). We recommend 0.1uumee which is equal the current Keplr average setting:

minimum-gas-prices = "0.1uumee"

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 check your price feeder config is up to date.
• Restart the chain.

You can use Cosmovisor → see instructions.

Docker

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

v5.0.1

Release Notes

Release Procedure is defined in the CONTRIBUTING document.

v5.0.1

Patch release: Cosmos SDK updated related to the barberry advisory.

v5.0.0

Highlights:

• Cosmwasm integration (v0.31).
• Gravity Bridge phase-3: shutdown of the transfers. In this release we introduce valset burn mechanism,
  which will block the Ethereum smart contract for processing any further transactions, as well
  as sending transfers back to Ethereum. This follows the plan approved through in the
  prop-67.
  NOTE: All validators must continue to use Peggo to not get slashed.
• Updated to the latest Cosmos SDK v0.46.12
• New generic functions for storage management: util/store.

See CHANGELOG.

libwasmvm update

Our dependencies have been updated. Now the binary requires libwasmvm v1.2.4. 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 $GOPATH/pkg/mod/github.com/!cosm!wasm/wasmvm@v1.2.4/internal/api/libwasmvm.$(uname -m).so
• or download from github wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.2.4/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.

You MUST also set the related parameter when starting Peggo --cosmos-gas-prices="0.1uumee"

• Make sure libwasmvm.$(uname -m).so is properly linked
  • Run the binary to make sure it works for you: umeed version

v4.4.1

Release Notes

Release Procedure is defined in the CONTRIBUTING document.

v4.4.1

Patch release updating ibc-go to the most recent patch release.

Please update as soon as possible.

See v4.4.0 for more details about the v4.4.x line.

See CHANGELOG for a full list of changes.

v4.4.0

This is a small, intermediate release.

For the Stride onboarding process, we decided to disable the IBC ICS-20 inflow limit of x/leverage registered tokens only. That means, now all tokens will be available for inflow transfers. IBC outflow quota will still hold: unregistered tokens can be transferred out without any limit and x/leverage registered tokens are limited to the daily quota.

No extra changes are required during this upgrade: all dependencies are the same as in v4.3.0.

See CHANGELOG for a full list of changes.
