+# 0.0.111 - Sep 12, 2022 - "Saturated with Messages"
+
+## API Updates
+ * Support for relaying onion messages has been added via a new
+ `OnionMessenger` struct when passed as the `OnionMessageHandler` to a
+ `PeerManager`. Pre-encoded onion messages can also be sent and received
+ (#1503, #1650, #1652, #1688).
+ * Rate-limiting of outbound gossip syncs has been rewritten to utilize less
+ buffering inside LDK. The new rate-limiting is also used for onion messages
+ to avoid delaying other messages (#1604. #1660, #1683).
+ * Rather than spawning a full OS thread, `lightning-background-processor` has
+ a new `process_events_async` method which takes the place of a
+ `BackgroundProcessor` for those using Rust's async (#1657).
+ * `ChannelManager::get_persistable_update_future` has been added to block on
+ a ChannelManager needing re-persistence in a Rust async environment (#1657).
+ * The `Filter::register_output` return value has been removed, as it was
+ very difficult to correctly implement (i.e., without blocking). Users
+ previously using it should instead pass dependent transactions in via
+ additional `chain::Confirm::transactions_confirmed` calls (#1663).
+ * `ChannelHandshakeConfig::their_channel_reserve_proportional_millionths` has
+ been added to allow configuring counterparty reserve values (#1619).
+ * `KeysInterface::ecdh` has been added as an ECDH oracle (#1503, #1658).
+ * The `rust-bitcoin` dependency has been updated 0.29 (#1658).
+ * The `bitcoin_hashes` dependency has been updated 0.11 (#1677).
+ * `ChannelManager::broadcast_node_announcement` has been moved to
+ `PeerManager` (#1699).
+ * `channel_` and `node_announcement`s are now rebroadcast automatically to all
+ new peers which connect (#1699).
+ * `{Init,Node}Features` sent to peers/broadcasted are now fetched via the
+ various `*MessageHandler` traits, rather than hard-coded (#1701, #1688).
+ * `Event::PaymentPathFailed::rejected_by_dest` has been renamed
+ `payment_failed_permanently` (#1702).
+ * `Invoice` now derives the std `Hash` trait (#1575).
+ * `{Signed,}RawInvoice::hash` have been renamed `signable_hash` (#1714).
+ * `chain::AccessError` now derives the std `Debug` trait (#1709).
+ * `ReadOnlyNetworkGraph::list_{channels,nodes}` have been added largely for
+ users of downstream bindings (#1651).
+ * `ChannelMonitor::get_counterparty_node_id` is now available (#1635).
+
+## Bug Fixes
+ * The script compared with that returned from `chain::Access` was incorrect
+ ~half of the time, causing spurious gossip rejection (#1666).
+ * Pending in-flight HTLCs are now considered when calculating new routes,
+ ensuring, e.g. MPP retries do not take known-saturated paths (#1643).
+ * Counterparty-revoked outputs are now included in `get_claimable_balance`
+ output via a new `Balance::CounterpartyRevokedOutputClaimable` (#1495).
+ * Inbound HTLCs for which we do not (yet) have a preimage are now included in
+ `get_claimable_balance` via a `Balance::MaybePreimageClaimableHTLC` (#1673).
+ * Probes that fail prior to being sent over their first hop are correctly
+ failed with a `Event::ProbeFailed` rather than a `PaymentPathFailed` (#1704).
+ * Pending `Event::HTLCHandlingFailed`s are no longer lost on restart (#1700).
+ * HTLCs that fail prior to being sent over their first hop are now marked as
+ retryable via `!PaymentPathFailed::payment_failed_permanently` (#1702).
+ * Dust HTLCs are now considered failed in the payment tracking logic after the
+ commitment transaction confirms, allowing retry on restart (#1691).
+ * On machines with buggy "monotonic" clocks, LDK will no longer panic if time
+ goes backwards (#1692).
+
+## Backwards Compatibility
+ * The new `current_time` argument to `PeerManager` constructors must be set to
+ a UNIX timestamp for upgraded nodes; new nodes may use a counter (#1699).
+ * `Balance::CounterpartyRevokedOutputClaimable` will never be generated for
+ channels that were observed to go on-chain with LDK versions prior to
+ 0.0.111 (#1495).
+ * `ChannelMonitor::get_counterparty_node_id` will return `None` for all
+ channels opened on a version of LDK prior to 0.0.110 (#1635).
+ * Setting `their_channel_reserve_proportional_millionths` to any value other
+ than the default will cause LDK versions prior to 0.0.104 to be unable to
+ read the serialized `ChannelManager` (#1619).
+
+## Security
+0.0.111 fixes a denial-of-service vulnerability which is reachable from
+untrusted input in deployments accepting 0conf channels, or via a race-condition
+in deployments creating outbound 0conf channels.
+
+ * LDK versions prior to 0.0.111 may spuriously panic when receiving a block if
+ they are awaiting the construction of a funding transaction for a 0-conf
+ channel (#1711). 0-conf support was added in LDK version 0.0.107.

0.0.98 should be considered a release candidate to the first alpha release of
Rust-Lightning and the broader LDK. It represents several years of work
don't hesitate to ask if the assigned party or previous commenters are still
working on it if it has been awhile.
+Any changes that have nontrivial backwards compatibility considerations should
+have an entry added in the `pending_changelog` folder which includes the
+CHANGELOG entries that should be added in the next release.

-//! This crate exposes functionality to rapidly sync gossip data, aimed primarily at mobile
+//! This crate exposes client functionality to rapidly sync gossip data, aimed primarily at mobile
//! devices.
//!
-//! The server sends a compressed response containing differential gossip data. The gossip data is
-//! formatted compactly, omitting signatures and opportunistically incremental where previous
-//! channel updates are known (a mechanism that is enabled when the timestamp of the last known
-//! channel update is communicated). A reference server implementation can be found
-//! [here](https://github.com/lightningdevkit/rapid-gossip-sync-server).
+//! The rapid gossip sync server will provide a compressed response containing differential gossip
+//! data. The gossip data is formatted compactly, omitting signatures and opportunistically
+//! incremental where previous channel updates are known. This mechanism is enabled when the
+//! timestamp of the last known channel update is communicated. A reference server implementation
+//! can be found [on Github](https://github.com/lightningdevkit/rapid-gossip-sync-server).
//!
-//! An example server request could look as simple as the following. Note that the first ever rapid
-//! sync should use `0` for `last_sync_timestamp`:
+//! The primary benefit of this syncing mechanism is that it allows a low-powered client to offload
+//! the validation of gossip signatures to a semi-trusted server. This enables the client to
+//! privately calculate routes for payments, and to do so much faster than requiring a full
+//! peer-to-peer gossip sync to complete.
+//!
+//! The server calculates its response on the basis of a client-provided `latest_seen` timestamp,
+//! i.e., the server will return all rapid gossip sync data it has seen after the given timestamp.
+//!
+//! # Getting Started
+//! Firstly, the data needs to be retrieved from the server. For example, you could use the server
+//! at <https://rapidsync.lightningdevkit.org> with the following request format:
//!
//! ```shell
//! curl -o rapid_sync.lngossip https://rapidsync.lightningdevkit.org/snapshot/<last_sync_timestamp>
//! ```
+//! Note that the first ever rapid sync should use `0` for `last_sync_timestamp`.
//!
-//! Then, call the network processing function. In this example, we process the update by reading
-//! its contents from disk, which we do by calling the `sync_network_graph_with_file_path` method:
+//! After the gossip data snapshot has been downloaded, one of the client's graph processing
+//! functions needs to be called. In this example, we process the update by reading its contents
+//! from disk, which we do by calling [sync_network_graph_with_file_path]:
//!
//! ```
//! use bitcoin::blockdata::constants::genesis_block;
//! let rapid_sync = RapidGossipSync::new(&network_graph);
//! let new_last_sync_timestamp_result = rapid_sync.sync_network_graph_with_file_path("./rapid_sync.lngossip");
//! ```
-//!
-//! The primary benefit this syncing mechanism provides is that given a trusted server, a
-//! low-powered client can offload the validation of gossip signatures. This enables a client to
-//! privately calculate routes for payments, and do so much faster and earlier than requiring a full
-//! peer-to-peer gossip sync to complete.
-//!
-//! The reason the rapid sync server requires trust is that it could provide bogus data, though at
-//! worst, all that would result in is a fake network topology, which wouldn't enable the server to
-//! steal or siphon off funds. It could, however, reduce the client's privacy by forcing all
-//! payments to be routed via channels the server controls.
-//!
-//! The way a server is meant to calculate this rapid gossip sync data is by using a `latest_seen`
-//! timestamp provided by the client. It's not included in either channel announcement or update,
-//! (not least due to announcements not including any timestamps at all, but only a block height)
-//! but rather, it's a timestamp of when the server saw a particular message.
