Versioning Strategy

Elsa adheres to a clear versioning strategy:

  • Released packages: Major.Minor.Revision (e.g., 3.0.1)
  • Release Candidate packages: Major.Minor.Revision-preview.X (e.g., 3.0.2-preview.64)
  • Preview packages: Major.Minor.Revision-preview.X (e.g., 3.0.2-preview.128)

The major version remains consistent unless significant changes occur. New features increment the minor version, while fixes or minor improvements bump the revision number.
