Software release numbering
The values in a software release version convey the significance of the software changes from one version to another. With each version release, you can infer the scope of change by the version number.
There are three main categories of software versions, which are tracked in the version number for a given release, written as major.minor.build number.
| Item | Category | Description | 
|---|---|---|
| 1 | Major | Rolls when there are significant changes in the functionality or its
                            components that require an important upgrade of the deployment. Changes
                            that qualify include: 
 Important: This release type can
                                introduce changes that are not compatible with the configuration of
                                an older version. In this case, MadCap Software provides
                                you with an upgrade procedure. |

| 3 | Build number | Introduces bug fixes through service packs or hot fixes, which may require small updates to the components. Note: No major upgrades are required. You may need
                                to make minor configuration changes, which are documented in the
                                related Upgrade Guide. Any change in the software must be backward
                                compatible. |
