Dear All, In tested a model that uses several calls to GetConnections for wiring multiple receptors. I tested it in 2.18 and 2.20, with different master seeds. The results are consistent. However, I would like to understand the meaning of that “warning”. Thanks, Carlos.

Dear All, I am experiencing the same issue changing from NEST 2.18 to 2.20. Apparently is an error masked as a "warning". I was reading the release notes -->> https://github.com/nest/nest-simulator/releases/tag/v2.20.0 and there is a fix for GetConnections -->> https://github.com/nest/nest-simulator/pull/1251 Probably an error was introduced in that change. Please can you help. Regards, Carlos.

Hi everybody,
I switched from Nest 2.16 to 2.20 and now I get this warning message:
*ConnectionManager [Warning]: *
- New connections created, connection descriptors previously obtained
using *
- 'GetConnections' are now invalid*
This happens at several parts in my code while building synapses with 'sim.Projection(...)'. I use a 'FromListConnector' and 'STDPMechanism' as synapse_type.
I neversaw this warning in the previous Nest version, is it something to be concerned about?
I am not quite sure what it is trying to tell me.
Thanks in advance, Lea
