# On Matrix tombstones
```json
{
"body": "This room has been replaced",
"replacement_room": "!NewRoomID:example.net"
}
```
Note [my scripts for tombstoning](https://gitea.blesmrt.net/mikaela/scripts/src/branch/master/bash),
`matrix-{tombstone,upgrade}-room.bash`.
## PL50 tombstoning
Synapse versions before [1.11.0 (2020-02-21), technically 1.11.0rc1 (2020-02-19)](https://github.com/matrix-org/synapse/releases/tag/v1.11.0)
allowed power level 50 to set tombstones and thus hijack rooms. Thus this is
dependent on the Synapse version used at the time of room creation.

- [commit](https://github.com/matrix-org/synapse/commit/3404ad289b1d2e5bc5c7f277f519b9698dbdaa15)
In the same context invites were changed to require PL50 by default, and ACL
also got the requirement for PL100.
