# Changelog
|
||||
|
||||
## Dendrite 0.6.5 (2022-03-04)
|
||||
|
||||
### Features
|
||||
|
||||
* Early support for push notifications has been added, with support for push rules, pushers, HTTP push gateways and the `/notifications` endpoint (contributions by [danpe](https://github.com/danpe), [PiotrKozimor](https://github.com/PiotrKozimor) and [tommie](https://github.com/tommie))
|
||||
* Spaces Summary (MSC2946) is now correctly supported (when `msc2946` is enabled in the config)
|
||||
* All media API endpoints are now available under the `/v3` namespace
|
||||
* Profile updates (display name and avatar) are now sent asynchronously so they shouldn't block the client for a very long time
|
||||
* State resolution v2 has been optimised further to considerably reduce the number of memory allocations
|
||||
* State resolution v2 will no longer duplicate events unnecessarily when calculating the auth difference
|
||||
* The `create-account` tool now has a `-reset-password` option for resetting the passwords of existing accounts
|
||||
* The `/sync` endpoint now calculates device list changes much more quickly with less RAM used
|
||||
* The `/messages` endpoint now lazy-loads members correctly
|
||||
|
||||
### Fixes
|
||||
|
||||
* Read receipts now work correctly by correcting bugs in the stream positions and receipt coalescing
|
||||
* Topological sorting of state and join responses has been corrected, which should help to reduce the number of auth problems when joining new federated rooms
|
||||
* Media thumbnails should now work properly after having unnecessarily strict rate limiting removed
|
||||
* The roomserver no longer holds transactions for as long when processing input events
|
||||
* Uploading device keys and cross-signing keys will now correctly no-op if there were no changes
|
||||
* Parameters are now remembered correctly during registration
|
||||
* Devices can now only be deleted within the appropriate UIA flow
|
||||
* The `/context` endpoint now returns 404 instead of 500 if the event was not found
|
||||
* SQLite mode will no longer leak memory as a result of not closing prepared statements

||||

Dendrite is a second-generation Matrix homeserver written in Go.
|
||||
It intends to provide an **efficient**, **reliable** and **scalable** alternative to [Synapse](https://github.com/matrix-org/synapse):
|
||||
- Efficient: A small memory footprint with better baseline performance than an out-of-the-box Synapse.

|
||||
a [brand new Go test suite](https://github.com/matrix-org/complement).

- Scalable: can run on multiple machines and eventually scale to massive homeserver deployments.

|

|

As of October 2020, Dendrite has now entered **beta** which means:
|
||||
|
||||
- Dendrite is ready for early adopters. We recommend running in Monolith mode with a PostgreSQL database.
|
||||
- Dendrite has periodic semver releases. We intend to release new versions as we land significant features.
|
||||
- Dendrite supports database schema upgrades between releases. This means you should never lose your messages when upgrading Dendrite.
|
||||
- Breaking changes will not occur on minor releases. This means you can safely upgrade Dendrite without modifying your database or config file.
|
||||
|
||||
This does not mean:
|
||||
- Dendrite is bug-free. It has not yet been battle-tested in the real world and so will be error prone initially.
|
||||
- All of the CS/Federation APIs are implemented. We are tracking progress via a script called 'Are We Synapse Yet?'. In particular,

||||
presence and push notifications are entirely missing from Dendrite. See [CHANGES.md](CHANGES.md) for updates.

Currently, we expect Dendrite to function well for small (10s/100s of users) homeserver deployments as well as P2P Matrix nodes in-browser or on mobile devices.
|
||||
In the future, we will be able to scale up to gigantic servers (equivalent to matrix.org) via polylith mode.

To build Dendrite, you will need Go 1.16 or later.

For a usable federating Dendrite deployment, you will also need:
|

- A domain name (or subdomain)
|

|
||||
- A domain name (or subdomain)
|
||||
- A valid TLS certificate issued by a trusted authority for that domain
|
||||
- SRV records or a well-known file pointing to your deployment
|
||||
|
||||
Also recommended are:
|
||||
|
||||
- A PostgreSQL database engine, which will perform better than SQLite with many users and/or larger rooms
|
||||
- A reverse proxy server, such as nginx, configured [like this sample](https://github.com/matrix-org/dendrite/blob/master/docs/nginx/monolith-sample.conf)

We use a script called Are We Synapse Yet which checks Sytest compliance rates. Sytest is a black-box homeserver

test rig with around 900 tests. The script works out how many of these tests are passing on Dendrite and it

updates with CI. As of March 2022 we're at around 76% CS API coverage and 95% Federation coverage, though check

CI for the latest numbers. In practice, this means you can communicate locally and via federation with Synapse
|
||||
servers such as matrix.org reasonably well. There's a long list of features that are not implemented, notably:
|
||||
- Push
|

- Search and Context
|

- User Directory
|

- Guests
|

- Search

- User Directory
|

- Presence
|

|

We are prioritising features that will benefit single-user homeservers first (e.g Receipts, E2E) rather
|
||||
than features that massive deployments may be interested in (User Directory, OpenID, Guests, Admin APIs, AS API).
|
||||
This means Dendrite supports amongst others:
|

- Core room functionality (creating rooms, invites, auth rules)
|

- Federation in rooms v1-v7
|

- Backfilling locally and via federation
