This room version builds on [version 1](/rooms/v1) with an improved
|
|
state resolution algorithm.

|
## Client considerations

|
|
There are no client considerations introduced in this room version. Clients
|
|
which implement the redaction algorithm locally should refer to the
|
|
[redactions](#redactions) section below for a full overview of the algorithm.
