# MSC3904: Room version 10 as a default
|
|
|
|
Enough time has passed to allow the public federation to upgrade their servers to support room
|
|
version 10, though with some caveats (see "potential issues"). This proposal aims to make v10 the
|
|
default room version.
|
|
|
|
## Proposal
|
|
|
|
The specification adopts v10 as the suggested default room version, making no changes to the stability
|
|
of any room versions. As of writing, v9 is currently the suggested room version.
|
|
|
|
Room version 10 is currently published here: https://spec.matrix.org/v1.4/rooms/v10/
|
|
|
|
## Potential issues
|
|
|
|
Servers will be encouraged to update their config/internal defaults to use v10 instead of v9. This
|
|
is considered a good problem to have.
|
|
|
|
Note that servers are not required to honour the default room version due to it being a suggestion
|
|
in the specification, however they might fall behind as other servers set their defaults accordingly.
|
|
|
|
Some server implementations, like Synapse, support configurable default room versions: servers which
|
|
have set this flag will not necessarily be affected by this change.
|
|
|
|
As of writing (2022-10-09) Synapse and Dendrite both have supported Room version 10 since 2022-08-02
|
|
when Synapse in 1.64.0 added its support. Dendrite added its support back in 2022-06-01. This leaves
|
|
Conduit as the only major implementation to lack v10 support.
|
|
|
|
Conduit status for v10 is not implemented as of (2022-10-09) but has been reported that its getting close
|
|
by Conduit developer Timo. Ruma has it implemented and the Catalyst Conduit fork has v10 working
|
|
for about as long as Synapse has had its implementation based on the memory of the Author of this MSC.

## Alternatives
|
|
|
|
None relevant.
|
|
|
|
## Security considerations
|
|
|
|
None relevant.
|
|
|
|
## Unstable prefix
|
|
|
|
None relevant - servers can already choose a different default room version legally. This MSC
|
|
just formalizes v10 as the default.
