Can someone help me understand the decimal numbers in the 3GPP release here after 12? This is an example.

Rightmost column has 3GPP release numbers for CA bands

Intuitively I can tell they are incremental releases, later ones have higher numbers after decimal... I want some accurate info on what makes a CA Band combo 3GPP Release 12.5 not 12.6? Thanks.

  • \$\begingroup\$ Thank you @BrianDrummond The link helped: In the version number of a 3GPP TS or TR, the first field (before the first dot) indicates the Release number according to the table below. The field "x" is incremented at each change in the spec resulting from one or more Change Requests approved by the responsible TSG. Field "y" is incremented whenever an editorial change is made to a specification; editorial changes are those which cannot in any way change the technical interpretation of the spec, and are introduced at the discretion of the Support Team.... \$\endgroup\$ – Sanjeev Oct 3 at 5:30
