 This is the third alpha release of `lightning-liquidity`. It features
 a number of bug fixes and performance improvements over the previous release.
 
-Notably, it introduces service-side payment sequencing in LSPS2, ensuring
-we'll only have one intercepted payment in-flight at any given point in time,
-until one has paid the channel opening fee. Moreover, this release fixes a
-previously introduced deadlock when being unable to parse a received message.
+Notably, it introduces service-side payment sequencing in LSPS2, ensuring we'll
+only have one intercepted payment in-flight at any given point in time, which
+allows the LSP to keep deducting the channel opening fee from the intercepted
+payments until one actually succeeds. Moreover, this release fixes a previously
+introduced deadlock when being unable to parse a received message.
 
 **Note:** This release is still considered experimental, should not be run in
 production, and no compatibility guarantees are given until the release of 0.1.0.
