vmware spring for graphql UPGRADE

Affected: >= 1.3.0 and < 1.3.10 · >= 1.4.0 and < 1.4.7 · >= 2.0.0 and < 2.0.4.1

Fixed in: 1.3.10, 1.4.7, 2.0.4.1

Safe to downgrade to: a release before 1.3.0

1. Check installed version

apt-cache policy spring-for-graphql || rpm -q spring-for-graphql || spring-for-graphql --version

2. UPGRADE to 1.3.10 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-for-graphql

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-for-graphql

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 spring-for-graphql sudo apt install spring-for-graphql=<VERSION_BEFORE_1.3.0> sudo apt-mark hold spring-for-graphql

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

dnf --showduplicates list spring-for-graphql sudo dnf downgrade spring-for-graphql-<VERSION_BEFORE_1.3.0> sudo dnf versionlock add spring-for-graphql

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.
