What if a gateway update causes errors?
As you can see from my screenshot there can be many, many corrections issued between regular releases. September 2025 had five versions, for example, and the latest August version was sneakily inserted AFTER the first September version was released.
Of course you can take your own conclusions from that but we have been badly burned in the past by this, and are now extra extra cautious, updating a canary first and then waiting how it behaves. There are tons of feature changes between versions, nearly none of them documented (the latest 0.20 Spark drama for example).
There be dragons.
as perfectly stated by lbendlin you cannot revert so we use the same tecnique for all our customers even if they've a cluster or not. we store every installer of each version of the gateway monthly and we backup all the configurations files before upgrading. in case of emergency we uninstall the gateway and we install the older version with the correct configuration files.
another approach we used for some other clients is to snapshot the VM before upgrading and keep it alive until we have green light.
having test environment, cluster, not to install if the gateway had been released few minutes ago etc. are good suggestions obviously.
