# MSC 1813 - Federation Make Membership Room Version
|
||
|
|
|
||
|
|
This proposal adds a new `room_version` field to the responses of `/make_leave`
|
||
|
|
and `/make_join` APIs.
|
||
|
|
|
||
|
|
## Motivation
|
||
|
|
|
||
|
|
It is planned for future room versions to be able to change the format of events
|
||
|
|
in various ways. To support this, all servers must know the room version
|
||
|
|
whenever they need to parse an event. Currently the `/make_*` APIs do not
|
||
|
|
include the room version in the response, so the requesting server is unable to
|
||
|
|
parse the event included in the response body.
|
||
|
|
|
||
|
|
## Proposal
|
||
|
|
|
||
|
|
Add a new `room_version` field to the response body of the `v1` `/make_join` and
|
||
|
|
`/make_leave` APIs, which describes the room version.
|
||
|
|
|
||
|
|
For backwards compatibility servers must correctly handle responses that do not
|
||
|
|
include the new field. In which case the room version is assumed to be one of
|
||
|
|
either `1` or `2`.
