CMX - Build versus image version

what is the difference between the 'build version" and "image version" in CMX?

E.g. :

[cmxadmin@avitosin-1 ~]$ cmxctl version

----------------------------------------------------------------------

Build Version : 10.2.3-271

Build Time : 2016-10-11 22:08:30.577964

----------------------------------------------------------------------

Image Version : 10.2.3-34

----------------------------------------------------------------------

[cmxadmin@avitosin-1 ~]$  

/api/config/v1/version/image

{"cmx_image_version":"CISCO_CMX-10.2.3-34.cmx","cmx_rpm_versions":["cisco_cmx_connect-10.2.3-28","cisco_cmx_wips-10.2.0-96","cisco_cmx-10.2.3-271"]}

I believe each of the builds are incremental, where the image are release packages.

The cmx image version is what I refer to when communicating with CMX BU folks.

[cmxadmin@cmx share]$ cd /opt/image/

[cmxadmin@cmx image]$

[cmxadmin@cmx image]$ cat CISCO_CMX-10.2.3-34.json

{

    "cmx_rpm_versions": [

        "cisco_cmx_connect-10.2.3-28",

        "cisco_cmx_wips-10.2.0-96",

        "cisco_cmx-10.2.3-271"

    ],

    "cmx_image_version": "CISCO_CMX-10.2.3-34.cmx"

}[cmxadmin@cmx image]$

[cmxadmin@cmx ~]$ cat /opt/cmx/share/version.json

{

    "buildtime": "2016-10-11 22:08:30.577964",

    "version": "10.2.3-271",

    "repositories": [
