[sr-dev] master siptrace not backwards compatible

[Henning Westerholt]

Hello Juha,

I think we don't have a policy that mandates strict backward 
compatiblity going from one major version to another. This only applies 
to minor version upgrades.

Have a look e.g. to this link, from 5.1 to 5.2 we also broke the 
compatibility for some modules there (e.g. dispatcher).

https://www.kamailio.org/wiki/install/upgrade/5.1.x-to-5.2.0

That said, we should of course try to not break configurations without a 
proper reason. All backward incompatible changes needs to be documented 
in the migration document for the upcoming 5.3 version.

Cheers,

Henning
