 ## Bug Fixes
+ * Fixed a bug where a delay in processing a `PaymentSent` event longer than the
+   time taken to persist a `ChannelMonitor` update, when ocurring immediately
+   prior to a crash, may result in the `PaymentSent` event being lost (#2048).
+ * Fixed spurious rejections of rapid gossip sync data when the graph has been
+   updated by other means between gossip syncs (#2046).
  * 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).
