Ah, so I bumped this here so that it didn't matter if we merged your PR that bumped in the mean time. I don't think we actually need to bump the schema version for this PR.

I think the list below still needs an summary of the sliding sync connection tables being added

It looks like we're no longer taking access_token into account for the sliding_sync_connections table. Are we ok with the potential collisions?

If we care, we should add a test to make sure we don't regress this kind of thing.

Ugh, I'd forgotten I had a to do for that. My hunch is that ideally we'd always have sliding sync attached to a device so that eg we can tie it to last time we saw a device. We also don't generally use sliding sync with pupetted access (which is the common way we don't have a device). I'll have a think

I've renamed it to effective_device_id and added a comment.

Discussed in an internal meeting today

The column having the new name effective_device_id is good enough but we're not going to address taking access_token into account in this PR because the only users that won't have a device_id are application services. And since we block application services from using sync anyway, this doesn't matter now.

We can always support it in the future and the column already has a good name if we decide to support it.

This is so that we can cache it.

We also move the sliding sync types to
`synapse/types/handlers/sliding_sync.py`. This is mainly in-prep for
#17599 to avoid circular imports.

The only change in behaviour is that
`RoomSyncConfig.combine_sync_config(..)` now returns a new room sync
config rather than mutating in-place.

Reviewable commit-by-commit.

# Synapse 1.114.0 (2024-09-02)

This release enables support for
[MSC4186](matrix-org/matrix-spec-proposals#4186) —
Simplified Sliding Sync. This allows using the upcoming releases of the Element
X mobile apps without having to run a Sliding Sync Proxy.

- Enable native sliding sync support ([MSC3575](matrix-org/matrix-spec-proposals#3575) and [MSC4186](matrix-org/matrix-spec-proposals#4186)) by default. ([\#17648](element-hq/synapse#17648))




# Synapse 1.114.0rc3 (2024-08-30)

### Bugfixes

- Fix regression in v1.114.0rc2 that caused workers to fail to start. ([\#17626](element-hq/synapse#17626))




# Synapse 1.114.0rc2 (2024-08-30)

- Fix authenticated media responses using a wrong limit when following redirects over federation. ([\#17543](element-hq/synapse#17543))

### Internal Changes

- Refactor sliding sync class into multiple files. ([\#17595](element-hq/synapse#17595))
- Store sliding sync per-connection state in the database. ([\#17599](element-hq/synapse#17599))
