  * Reduced RAM usage.
+ * Bugfix: hosts that use variable length rendering blocks could cause JS80P in
+   some circumstance to leave garbage in the buffers of delay based effects
+   when they decayed into silence, which (depending on the settings of the
+   patch) could produce audible glitches. Now the delay buffers are properly
+   cleaered when both their input and their feedback line decays into silence.
  * Bugfix: despite the efforts in v1.5.1, in some circumstances, short delay
    times (lower than 3-5 milliseconds) could still make the feedback lines
-   noisy in delay based effects in hosts which use variable rendering block
-   size (e.g. FL Studio). The rendering logic has been adjusted to prevent
+   noisy in delay based effects in hosts which use variable length rendering
+   blocks (e.g. FL Studio). The rendering logic has been adjusted to prevent
    delay feedback lines from falling behind and becoming discontinuous when the
    host requests a large rendering batch after a sequence of short ones.
