Update

Compatibility

Before updating users should identify the version in use by JS7 Components and the indicated compatibility, see JS7 - Compatibility Indicator.

Applicability

• For most updates the JOC Cockpit and the Controller are required to use the same maintenance release, for example 2.2.2.
• Existing Agents can continue to be operated with newer Controller releases within the same minor release, for example 2.2.
  • Newer minor Agent releases cannot be used with an older minor Controller release: for example, an Agent 2.2 will not work with a Controller 2.1.
  • Older minor Agents releases cannot be used with newer minor Controller releases: for example, an Agent 2.1 will not work with a Controller 2.2.
