* RLN_v2 is used. The maximum rate can be set to `N` messages per epoch, instead of just one message per epoch. See [this](https://github.com/waku-org/nwaku/issues/2345) for more details. Notice that we established an epoch of 10 minutes.
* Named sharding will be deprecated in favor of static sharding. Topics in formats other than `/waku/2/rs/<cluster>/<shard>` will stop being supported starting from `v0.31.0`

> Flag allows using wildcards (`*` and `?`) in the origin string.

> Waku Filter v2 now has three additional configuration options
> `--filter-max-peers-to-serve=1000` drives how many peers can subscribe at once and
> `--filter-max-criteria=1000` defines what is the maximum criterion stored per each peers
>
> This release introduces a major change in Filter v2 protocol subscription management.
> From now each subscribed peer needs to refresh its living subscriptions by sending a SUBSCRIBER_PING message every 5 minutes by default, otherwise the peer's subscription will be removed.
> `--filter-subscription-timeout=300` defines configurable timeout for the subscriptions (*in seconds*).
>
> New experimental feature, shard aware peer manager for relay protocol can be activated by the flag:
> `--relay-shard-manager=true|false`
> It is disabled by default.
> **Announcement:**
>
> Please notice that from the next release (0.26.0) we will deprecate features.
>
> - JSON-RPC API will be removed completely. Instead we recommend you to utilize REST API endpoints that have same and extended functionality.
> - We will retire websockets support for RLN on-chain group management. You are expected to use HTTP version of ETH_CLIENT_ADDRESS

## Upgrade instructions
There is a new naming scheme for release artifacts - `nwaku-${ARCHITECTURE}-${OS}-${VERSION}.tar.gz`. If you use any automation to download latest release, you may need to update it.
The `--topics` config option has been deprecated to unify the configuration style. It is still available in this release but will be removed in the next one. The new option `--topic` is introduced, which can be used repeatedly to achieve the same behavior.
> Note that the --topics config item has been deprecated and support will be dropped in future releases. To configure support for multiple pubsub topics, use the new --topic parameter repeatedly.
* Support for Heaptrack to investigate memory utilization ([tutorial](https://github.com/waku-org/nwaku/blob/master/docs/tutorial/heaptrack.md)).

## Upgrade instructions
* The `--topics` config option has been deprecated to unify the configuration style. It still available in this and will be in next release, but will be removed after that. The new option `--topic` is introduced, which can be use repeatedly to achieve the same behaviour.
- a fix for an issue that prevented the node from generating high-resolution (up to nanosecond) timestamps
- introduction of an application-defined `meta` attribute to the Waku Message. This can be quite valuable for network-wide deduplication, deterministic hashing, validity checking and other planned improvements to the protocol
- many optimizations in RLN implementation and its underlying dependencies

- Start of an HTTP REST API implementation.
- Support for a memory-efficient SQLite-only `store` configuration.
### Changes
- Added index on `receiverTimestamp` in the SQLite `store` to improve query performance.
- GossipSub [Peer Exchange](https://github.com/libp2p/specs/blob/master/pubsub/gossipsub/gossipsub-v1.1.md#prune-backoff-and-peer-exchange) is now disabled by default. This is a more secure option.

- Fixed underlying issues that caused WebSocket connections to hang.
- Fixed underlying issue that caused WebSocket connections to time out after 10 mins.
- Fixed memory leak in nodes that implements a SQLite database.
