- Updated the deployment command in deploy.sh to utilize the new SPIN_SWARM_STACK_NAME variable, enhancing clarity and consistency in stack naming.
- Introduced SPIN_SWARM_STACK_NAME to allow for customizable stack names based on the project and environment, improving flexibility in deployment configurations.
