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
