v6.0.1
Release Notes
Release Procedure is defined in the CONTRIBUTING document.
v6.0.1
This is a bug fix release for the leverage.MsgGovUpdateSpecialAssets
handler.
We also added umeed q ugov emergency-group
CLI query. Users were able to query the Emergency Group address using REST.
v6.0.0
Highlights:
- We introduce Special Assets: a new primitive to optimize positions in x/leverage.
- New inflation mechanism.
- Emergency Groups.
- Full Gravity Bridge removal. We don't include GB module any more in Umee.
- New
MsgLeveragedLiquidate.MaxRepay
which allows to limit the liquidation size using the leveraged liquidation mechanism. - Renamed ugov
EventMinTxFees
toEventMinGasPrice
.
New Inflation Mechanism
The Upgrade Handler sets the following values to the Umee x/ugov
Inflation Cycle parameters:
max_supply = 21e18uumee
(21 billions UMEE)inflation_cycle = time.Hour * 24 * 365 * 2
(2 years)inflation_reduction_rate = 2500 basis points
(25%)
The new Inflation Cycle will start on 2023-10-15 15:00 UTC. This will mark the first inflation reduction from the current rates:
inflation_min
7% → 5.25%inflation_max
14% → 10.5%
The x/staking Bonded Goal stays the same: 33.00%.
Emergency Groups
Currently, any parameter update requires going through a standard governance process, which takes 4 days. In a critical situation we need to act immediately:
- Control IBC Quota parameters (eg disable IBC)
- apply safe updates to oracle, leverage or incentive module parameters.
Emergency Group can trigger safe parameter updates at any time as a standard transaction. The Emergency Group address is controlled by the Umee Chain governance (x/gov
) and can be disabled at any time.
Validators
libwasmvm update
Our dependencies have been updated. Now the binary requires libwasmvm v1.3.0
. 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
$GOPATH/pkg/mod/github.com/!cosm!wasm/wasmvm@v1.3.0/internal/api/libwasmvm.$(uname -m).so
- or download from github
wget https://raw.githubusercontent.com/CosmWasm/wasmvm/v1.3.0/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.
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
- Run the binary to make sure it works for you:
- 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.
