+# 0.0.114 - XXX - "Faster Async BOLT12 Retries"
+
+## API Updates
+ * `InvoicePayer` has been removed and its features moved directly into
+   `ChannelManager`. As such it now requires a simplified `Router` and supports
+   `send_payment_with_retry` (and friends) (#1812, #1916, #1929, #2007, etc).
+ * `Sign`/`BaseSign` has been renamed `ChannelSigner`, with `EcdsaChannelSigner`
+   split out in anticipation of future taproot support (#1967).
+ * The catch-all `KeysInterface` was split into `EntropySource`, `NodeSigner`,
+   and `SignerProvider`. `KeysManager` implements all three (#1910, #1930).
+ * A `lightning-transaction-sync` crate has been added which implements keeping
+   LDK in sync with the chain via an esplora server (#1870). Note that it can
+   only be used on nodes that *never* ran a previous version of LDK.
+ * `Score` is updated in `BackgroundProcessor` instead of via `Router` (#1996).
+ * `ChainAccess::get_utxo` (now `UtxoAccess`) can now be resolved async (#1980).
+ * BOLT12 `Offer`, `InvoiceRequest`, `Invoice` and `Refund` structs as well as
+   associated builders. Such invoices cannot yet be paid due to missing support
+   for blinded path payments (#1927, #1908, #1926).
+ * A `lightning-custom-message` crate has been added to make combining multiple
+   custom messages into one enum/handler easier (#1832).
+ * `lightning-net-tokio` no longer requires an `Arc` on `PeerManager` (#1968).
+ * `ChannelManager::list_recent_payments` was added (#1873).
+ * `lightning-background-processor` `std` is now optional in async mode (#1962).
+ * `create_phantom_invoice` can now be used in `no-std` (#1985).
+ * The required final CLTV delta on inbound payments is now configurable (#1878)
+ * `historical_estimated_channel_liquidity_probabilities` was added (#1961)
+ * `ChannelManager::fail_htlc_backwards_with_reason` was added (#1948).
+ * Macros which implement serialization using TLVs or straight writing of struct
+   fields are now public (#1823, #1976, #1977).
+
+## Backwards Compatibility
+ * Any inbound payments with a custom final CLTV delta will be rejected by LDK
+   if you downgrade prior to receipt (#1878).
+ * `Event::PaymentPathFailed::network_update` will always be `None` if an
+   0.0.114-generated event is read by a prior version of LDK (#2043).
+ * `Event::PaymentPathFailed::all_paths_removed` will always be false if an
+   0.0.114-generated event is read by a prior version of LDK. Users who rely on
+   it to determine payment retries should migrate to `Event::PaymentFailed`, in
+   a separate release prior to upgrading to LDK 0.0.114 if downgrading is
+   supported (#2043).
+
+## Performance Improvements
+ * Channel data is now stored per-peer and channel updates across multiple
+   peers can be operated on simultaneously (#1507).
+ * Routefinding is roughly 1.5x faster (#1799).
+ * Deserializing a `NetworkGraph` is roughly 6x faster (#2016).
+ * Memory usage for a `NetworkGraph` has been reduced substantially (#2040).
+ * `KeysInterface::get_secure_random_bytes` is roughly 200x faster (#1974).
+
+## Bug Fixes
+ * Fixed a panic in `KeysManager` when the high bit of `starting_time_nanos`
+   is set (#1935).
+ * Resolved a memory leak when using `ChannelManager::send_probe` (#2037).
+ * Fixed a deadlock on some platforms at least when using async `ChannelMonitor`
+   updating (#2006).
+ * Removed debug-only assertions which were reachable in threaded code (#1964).
+ * Return an `Err` if `lightning-persister` fails to read the directory listing
+   rather than panicing (#1943).
+ * `peer_disconnected` will now never be called without `peer_connected` (#2035)
+
+## Security
+0.0.114 fixes a denial-of-service vulnerability which is reachable from
+untrusted input in deployments accepting inbound connections or channels.
+ * The number of pending un-funded channels as well as peer without funded
+   channels is now limited to avoid denial of service (#1988).
