+# 0.0.115 - Apr 24, 2023 - "XXX"
+
+## API Updates
+ * The MSRV of the main LDK crates has been increased to 1.48 (#2107).
+ * Attempting to claim an un-expired payment on a channel which has closed no
+   longer fails. The expiry time of payments is exposed via
+   `PaymentClaimable::claim_deadline` (#2148).
+ * `payment_metadata` is now supported in `Invoice` deserialization, sending,
+   and receiving (via a new `RecipientOnionFields` struct) (#2139, #2127).
+ * `Event::PaymentFailed` now exposes a failure reason (#2142).
+ * BOLT12 messages now support stateless generation and validation (#1989).
+ * `Event::PaymentPathFailed::retry` was removed and will always be `None` for
+    payments initiated on 0.0.115 which fail on an earlier version (#2063).
+ * Max HTLCs in-flight is now configurable via `our_max_accepted_htlcs` (#2138).
+ * `lightning-transaction-sync` feature `esplora-async-https` was added (#2085).
+ * A `ChannelPending` event was added (#2098).
+ * `PaymentForwarded::amount_forwarded_msat` was added (#2136).
+ * `ChannelManager::list_channels_by_counterparty` was added (#2079).
+ * `ChannelDetails::feerate_per_kw` was added (#2094).
+ * `Invoice::fallback_addresses` was added to fetch `bitcoin` types (#2023).
+
+## Bug Fixes
+ * Fixed a case where `process_events_async` may `poll` a `Future` which has
+   already completed (#2081).
+ * Fixed deserialization of `u16` arrays. This bug may have previously corrupted
+   the historical buckets in a `ProbabilisticScorer`. Users relying on the
+   historical buckets may wish to wipe their scorer on upgrade to remove corrupt
+   data rather than waiting on it to decay (#2191).
+ * The `process_events_async` task is now `Send` and can thus be polled on a
+   multi-threaded runtime (#2199).
+ * Fixed a missing macro export causing
+   `impl_writeable_tlv_based_enum{,_upgradable}` calls to not compile (#2091).
+ * Fixed compilation of `lightning-invoice` with both `no-std` and serde (#2187)
+ * Fix an issue where the `background-processor` would not wake when a
+   `ChannelMonitorUpdate` completed asynchronously, causing delays (#2090).
+ * `Router` calls from the `ChannelManager` now call `find_route_with_id` rather
+   than `find_route`, as was intended and described in the API (#2092).
+ * `channel_update` messages no longer set the disable bit unless the peer has
+   been disconnected for some time. This should resolve cases where channels are
+   disabled for extended periods of time (#2198).
+ * Fixed a debug assertion which may panic under heavy load (#2172).
+ * `CounterpartyForceClosed::peer_msg` is now wrapped in UntrustedString (#2114)
+ * Fixed a potential deadlock in `funding_transaction_generated` (#2158).
+
+## Security
+ * Transaction re-broadcasting is now substantially more aggressive, including a
+   new regular rebroadcast feature called on a timer from the
+   `background-processor` or directly from the `ChainMonitor`. This should
+   substantially increase transaction confirmation reliability without relying
+   on downstream `TransactionBroadcaster` implementations for rebroadcasting
+   (#2203, #2205, #2208).
+ * Implemented the changes from BOLT PRs #1031, #1032, and #1040 which resolve a
+   privacy vulnerability which allows an intermediate node on the path to
+   discover the final destination for a payment (#2062).
