Define update strategy

Corewide DevOps team strictly follows Semantic Versioning Specification to provide our clients with products that have predictable upgrades between versions. We recommend pinning patch versions of our modules using pessimistic constraint operator (~>) to prevent breaking changes during upgrades.

To get new features during the upgrades (without breaking compatibility), use ~> 1.2 and run terraform init -upgrade

For the safest setup, use strict pinning with version = "1.2.1"

v1.2.1 released 2 years, 8 months ago
