# MSC3589: Room version 9 as a default
|
|
|
|
Enough time has passed to allow the public federation to upgrade their servers to support room
|
|
version 9, though with some caveats (see "potential issues"). This proposal aims to make v9 the
|
|
default room version.
|
|
|
|
## Proposal
|
|
|
|
The specification adopts v9 as the suggested default room version, making no changes to the stability
|
|
of any room versions. As of writing, v6 is currently the suggested room version.
|
|
|
|
Room version 9 is currently published here: https://spec.matrix.org/v1.2/rooms/v9/
|
|
|
|
## Potential issues
|
|
|
|
Servers will be encouraged to update their config/internal defaults to use v9 instead of v6. 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 (Jan 26, 2022), some prominent server implementations are only just getting support for
|
|
the room version. Namely, Dendrite released a version with support about 2 months ago and Conduit is
|
|
working on including Ruma's changes which landed also about 2 months ago.
|
|
|
|
Though both Dendrite and Conduit (meaning Ruma) have not had the same amount of time as Synapse to
|
|
reach maturity on v9-capable versions, both the Dendrite and Conduit communities appear to update to
|
|
newer versions much more quickly. This implies, without statistics to back it up, that nearly all
|
|
Dendrite servers out there will have upgraded and that a similar percentage of Conduit servers will
|
|
upgrade once available.
|
|
|
|
No major issues appear to be reported to Synapse or Dendrite with respect to v9, however Conduit
|
|
has [reported](https://gitlab.com/famedly/conduit/-/merge_requests/257#note_814327701) that the auth
|
|
rules for v9 might not be perfect. All of this indicates to the author that the implementation is at
|
|
least sane and accomplishable, even if a bit difficult to incorporate.
|
|

## 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 v9 as the default.
