Looks like my previous post was not sent to mailing list bu only to nabble forum so I am resending it. 

I plan to use declarative agenda API: kcontext.blockActivation, kcontext.unblockAllActivations, kcontext.cancelActivation. 

In Drools documentation there is written that this API is highly experimental: 

This feature is off by default and must be explicitly enabled, that is because it is considered highly experimental for the moment and will be subject to change.

Could you please let me know in which version you plan to make declarative agenda API, solution final? 

Thanks,
