v4.0.1

Release Notes

Release Procedure is defined in the CONTRIBUTING document.

v4.0.1

This release is a consensus breaking patch which contains a fix to how we handle assets with lowercase symbols on the leverage module. Relevant PR here.

Building from source will automatically link the libwasmvm.x86_64.so created as a part of the build process (you must build on the same host as you run the binary, or copy the libwasmvm.x86_64.so your lib directory).

If you build on system different than Linux amd64, then you need to download appropriate version of libwasmvm (eg from CosmWasm/wasmvm Releases) or build it from source (you will need Rust toolchain).

Otherwise you have to download libwasmvm. Please check Supported Platforms. Example:

wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.1.1/internal/api/libwasmvm.$(uname -m).so -P /lib/

Please see the CHANGELOG for an exhaustive list of changes.

Update instructions

• Note: Skip this step if you build binary from source and are able to properly link libwasmvm.
  • Download libwasmvm:

$ wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.1.1/internal/api/libwasmvm.$(uname -m).so -O /lib/libwasmvm.$(uname -m).so

• Wait for software upgrade proposal to pass and trigger the chain upgrade.
• Run latest Price Feeder (v2.0.3) - updated
• Swap binaries.
• Restart the chain.

You can use Cosmovisor → see instructions.

NOTE: BEFORE the upgrade, make sure the binary is working and libwasmvm is in your system. You can test it by running ./umeed-v4.0.0 --version.

Docker

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

price-feeder/v2.0.4-rc1

v2.0.4-rc1

This is the first release candidate for the price feeder v2.0.4 release.

price-feeder/v2.0.4

v2.0.4

This is v2.0.4 of the price feeder, designed to support osmosis-native assets. Main changes are:

• Enabling asset prices to be quoted in "OSMO"
• A small bug fix to the USD conversion logic

v4.0.0

Release Notes

Release Procedure is defined in the CONTRIBUTING document.

v4.0.0

This release contains the Historacle Upgrade, a pricing update which improves the way we treat quickly-changing prices in the leverage module.

• See the Historacle Design Doc for a description of how these prices are calculated.
• See the Leverage Module Spec for a description of how these prices are treated by the leverage protocol.

Please Note:

• This upgrade requires the use of Price Feeder V2.0.3 immediately after the Umee v4.0 Upgrade. Prior to this upgrade, you should stay on Price Feeder V2.0.2.
• To run the provided binary, you have to have libwasmvm.x86_64.so v1.1.1 in your system lib directory.

Building from source will automatically link the libwasmvm.x86_64.so created as a part of the build process (you must build on the same host as you run the binary, or copy the libwasmvm.x86_64.so your lib directory).

If you build on system different than Linux amd64, then you need to download appropriate version of libwasmvm (eg from CosmWasm/wasmvm Relases) or build it from source (you will need Rust toolchain).

Otherwise you have to download libwasmvm. Please check Supported Platforms. Example:

wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.1.1/internal/api/libwasmvm.$(uname -m).so -P /lib/

Additional highlights:

• 1694 MsgMaxWithdraw, MsgMaxBorrow and MsgRepay won't return errors if there is nothing to withdraw, borrow or repay respectively. Leverage ErrMaxWithdrawZero and ErrMaxBorrowZero has been removed.

Please see the CHANGELOG for an exhaustive list of changes.

Update instructions

• Note: Skip this step if you build binary from source and are able to properly link libwasmvm.
  • Download libwasmvm:

$ wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.1.1/internal/api/libwasmvm.$(uname -m).so -O /lib/libwasmvm.$(uname -m).so

• Run latest Price Feeder (v2.0.3) - updated
• Swap binaries.

v3.3.0

Release Notes

Release Procedure is defined in the CONTRIBUTING document.

v3.3.0

• For the mainnet, this release includes update from v3.1.x → v3.3.x. Please also look at the v3.2 Release Notes, notably the Gravity Bridge Slashing.
• For the Canon-2 testnet, this release includes update from v3.2.x → v3.3.x

v3.2.0 was not released on mainnet due to a bug in x/leverage gov messages migration to the new format which utilizes x/gov/v1 authorization system. The bug caused legacy token registry updates to break x/gov proposal queries. In v3.3 we fix that bug.

Additional highlights:

• Added QueryMaxWithdraw and MsgMaxWithdraw to allow user easily withdraw previously supplied tokens from the module back to the user balance.
• Updated Cosmos SDK to v0.46.7

Please see the CHANGELOG for an exhaustive list of changes.

Github Release

Sinice v3.2.0 new experimental features (disabled by default) are part of the linked binary. That changed the build process. Umeed officially doesn't support static CGO build (with CGO_ENABLED=1) any more. Github Actions only support build using Linux on amd64 -- we can not make a cross platform build using Github Actions (possible solution is to do it through Qemu emulator). So our Github release only contains source code archive and amd64 Linux binary.

To run the provided binary, you have to have libwasmvm.x86_64.so v1.1.1 in your system lib directory.

Building from source will automatically link the libwasmvm.x86_64.so created as a part of the build process (you must build on the same host as you run the binary, or copy the libwasmvm.x86_64.so your lib directory).

If you build on system different than Linux amd64, then you need to download appropriate version of libwasmvm (eg from CosmWasm/wasmvm Relases) or build it from source (you will need Rust toolchain).

Otherwise you have to download libwasmvm. Please check Supported Platforms. Example:

wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.1.1/internal/api/libwasmvm.$(uname -m).so -P /lib/

Update instructions

• Note: Skip this step if you build binary from source and are able to properly link libwasmvm.
  • Download libwasmvm:

$ wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.1.1/internal/api/libwasmvm.$(uname -m).so -O /lib/libwasmvm.$(uname -m).so

• Wait for software upgrade proposal to pass and trigger the chain upgrade.
• Run latest Peggo (v1.4.0) - updated (you should update as soon as you can, it's compatible with the existing chain version).
• Run latest Price Feeder (v2.0.2) - updated (you should update as soon as you can, it's compatible with the existing chain version).
• Swap binaries.
• Restart the chain.

There is a new option available in app.toml (in Base Configuration). Set iavl-disable-fastnode to true if you want to disable fastnode cache and reduce RAM usage (default is false).

# IAVLDisableFastNode enables or disables the fast node feature of IAVL.
# Default is false.
iavl-disable-fastnode = false

You can use Cosmovisor → see instructions.

• If you use Cosmovisor, and you didn't build binary from source in the validator machine, you have to download the respective libwasmvm into your machine. See the previous section for more details.

NOTE: BEFORE the upgrade, make sure the binary is working and libwasmvm is in your system. You can test it by running ./umeed-v3.3.0 --version.
