Enabling/disabling auto redeployment
Particularly relevant for development cases, after you deploy a snapshot to an environment, you may continue working on the snapshot and make changes to it. If auto-redeployment is disabled, you need to manually redeploy your snapshot changes to your environment to apply the latest version of the snapshot you are working on. If the auto-redeployment option is enabled, your snapshot changes are automatically redeployed to the deployed environments, excluding the environments tagged as production. Namely, if you have deployed your snapshot to a development environment and also to your production environment, then any changes made on your snapshot are automatically redeployed to the development environment but not the production. For the production environment, you need to do manual redeployment.
You can enable or disabled automatic snapshot redeployment from your user preferences panel.
