vmware spring ai UPGRADE

Affected: >= 1.0.0 and < 1.0.5 · >= 1.1.0 and < 1.1.4

Fixed in: 1.0.5, 1.1.4

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy spring-ai || rpm -q spring-ai || spring-ai --version

2. UPGRADE to 1.0.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-ai

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-ai

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 1.0.0 (Debian / Ubuntu)

apt-cache madison spring-ai sudo apt install spring-ai=<VERSION_BEFORE_1.0.0> sudo apt-mark hold spring-ai

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

dnf --showduplicates list spring-ai sudo dnf downgrade spring-ai-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add spring-ai

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.
