cosmwasm cosmwasm-std UPGRADE

Affected: >= 1.3.0 and < 1.4.4 · >= 1.5.0 and < 1.5.4 · >= 2.0.0 and < 2.0.2

Fixed in: 1.4.4, 1.5.4, 2.0.2

Safe to downgrade to: a release before 1.3.0

1. Check installed version

apt-cache policy cosmwasm-std || rpm -q cosmwasm-std || cosmwasm-std --version

2. UPGRADE to 1.4.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade cosmwasm-std

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade cosmwasm-std

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.3.0 (Debian / Ubuntu)

apt-cache madison cosmwasm-std sudo apt install cosmwasm-std=<VERSION_BEFORE_1.3.0> sudo apt-mark hold cosmwasm-std

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list cosmwasm-std sudo dnf downgrade cosmwasm-std-<VERSION_BEFORE_1.3.0> sudo dnf versionlock add cosmwasm-std

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
