How to merge json objects by grouping on key with jq

I have a JSON list which I want to merge on command line .

[
 {
   "ipaddress": "10.10.10.222",
   "name": "alice"
 },
 {
   "ipaddress": "10.20.20.77",
   "name": "bob"
 },
 {
   "version": "6.7",
   "name": "alice"
 },
 {
   "version": "5.2.2",
   "name": "bob"
 }
]

Expected Output:

{"name": "alice", "ipaddress": "10.10.10.222", "version": "6.7"},
{"name": "bob", "ipaddress": "10.20.20.77", "version": "5.2.2"}

can you help me? Thank you. bernd
