Can constants in messages be changed without troubles with respect to "old" data?
Hi guys,
If I change (or add/remove) fields in message files "old" messages, e. g. record in bags, can no longer be subscribed by the node using the new message description, because md5sum and stuff do no longer fit...
Now my question: What happens if I add/remove/modify constant definitions ( http://wiki.ros.org/msg#Constants ) in messages? Will I still be able to use bags I recorded prior to the changes?
Thanks in advance, Wolf
