How boomerang self-service can help you manage your mPulse environment

Version values.
mPulse boomerang versions correspond to boomerang releases. When you create your first mPulse app, you can choose either a fixed value (for example, 1.571.0) or the default value (for example, Company or System Default (currently 1.506.0)).

For details on applying these values to your mPulse app, see Apply a boomerang version to your mPulse app.
For details on applying a default value for your company, see Apply a default boomerang version for your company.

Version labels.
To help you choose the appropriate boomerang version, labels appear to the right to denote its type.
Version labels include:

• GA. The ​Akamai​ mPulse system-wide boomerang default version. In the absence of any other boomerang default setting, use this version as the default.
• Recommended. When mPulse tenants are created, the default boomerang version in the Company Settings is typically set to the current recommended version.
• Latest. The latest stable boomerang version released by ​Akamai​. Before using this boomerang version, contact your ​Akamai​ account team to learn more about it.
• Company or System Default. The current boomerang default version for the company that is set in Company Settings (see Apply a default boomerang version for your company).

This example shows the boomerang version selections that appear in the Boomerang Version menu and the Default Boomerang menu. The check mark indicates that Company or System Default (currently 1.506.0) is the being used for the selected app.
