## 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.

In the same context invites were changed to require PL50 by default, and ACL
|
|
also got the requirement for PL100.
