SonicWall uses this syntax, described in below table to describe version numbers for upgrade files:
upgrade-<major>.<minor>.<micro>-<build>.bin
To find out if any hotfixes have been applied, click System Status or Maintenance from the main navigation menu.
The version number for AMC (displayed in the bottom-left corner of every AMC page) and client software follows a similar pattern:
<major>.<minor>-<micro>-<build>
| Name | Description |
| major | The major release number. If this is the only number that is present, it indicates that this release contains significant new features plus fixes. It also indicates that it contains a full image of the entire system. |
| minor | The minor release number. If the version number contains only the major and minor numbers, it indicates that this release contains incremental features plus fixes. It also indicates that it contains a full image of the entire system. |
| micro | The micro release number. If the version number contains only the major, minor, and micro numbers, it indicates that this release contains a small number of features plus fixes. It also indicates that it contains a full image of the entire system. |
| build | An internal build number used by SonicWall. All releases contain a build number. |
