Re: Webkit Version to OS Version

Am I correct in thinking that every Webkit revision has been associated with an OS point release since Safari was initially released on 10.2? If so, is there a list of all released WebKit Versions and/or any way to associate that WebKit version with its corresponding OS point release? We’re trying to extrapolate some data from our web server’s traffic logs and we’re not receiving any information about specific OS versions but we ARE recording WebKit version – and if we can map that to an OS point release we can get some general idea of OS usage as well as determining product requirements for our webkit-dependent products.

From my own research:

    OS        WebKit

10.3.0        1.1

10.3.1        1.1

10.3.2        1.1

10.3.3        1.2

10.3.4        1.2.2

10.3.5        1.2.3

10.3.6        125.5.5

10.3.7        125.5.5

10.3.8        125.5.6

10.3.9        312.1

10.4.0        ???? - Forget to test - D'oh

10.4.1        412

10.4.2        412.6

Note. if you have applied all the latest Software Updates to 10.4.2 then WK is now at 412.7. 

I think that it is safe to assume that for all the OS versions listed that those are the minimum versions of WebKit you can expect to find. There may be other intermediary WebKits that aren't listed.
