Sigma lens not recognised

Hello,

This lens mounted on a Canon:
Sigma 12-24mm f/4.5-5.6 II DG HSM

is not recognized.

The number of the lens is 137

In the file canonmn.cpp, should I add after

{ 137, "Canon EF 85mm f/1.2L"                                       }, // 0
        { 137, "Sigma 18-50mm f/2.8-4.5 DC OS HSM"                          }, // 1
        { 137, "Sigma 50-200mm f/4-5.6 DC OS HSM"                           }, // 2
        { 137, "Sigma 18-250mm f/3.5-6.3 DC OS HSM"                         }, // 3
        { 137, "Sigma 24-70mm f/2.8 IF EX DG HSM"                           }, // 4
        { 137, "Sigma 18-125mm f/3.8-5.6 DC OS HSM"                         }, // 5
        { 137, "Sigma 17-70mm f/2.8-4 DC Macro OS HSM"                      }, // 6
        { 137, "Sigma 17-50mm f/2.8 OS HSM"                                 }, // 7
        { 137, "Sigma 18-200mm f/3.5-6.3 II DC OS HSM"                      }, // 8
        { 137, "Tamron AF 18-270mm f/3.5-6.3 Di II VC PZD"                  }, // 9

//New line : { 137, "Sigma 12-24mm f/4.5-5.6 II DG HSM" }, // 10

Is there anything else, I need to do ?

Cheers,
Fabien

Hi,
I tried with the new line in canonmn.cpp:
//New line : { 137, "Sigma 12-24mm f/4.5-5.6 DG HSM II" }, // 10

and it works.
Can someone who has access to the Exiv2 repository add this line.

This lens is aspherical.
I hesitate with the exact name :
//New line : { 137, "Sigma 12-24mm f/4.5-5.6 DG HSM II" }, // 10
//New line : { 137, "Sigma 12-24mm f/4.5-5.6 DG ASPHERICAL HSM II" }, // 10

On the website of sigma, its official name :
