 Bug Fixes

-- A use-after-free assertion might get triggered when the overmem cache
-  cleaning triggers. :gl:`#4595`
-
-  ISC would like to thank to Jinmei Tatuya from Infoblox for bringing
-  this issue to our attention.
-
 - A regression in cache-cleaning code enabled memory use to grow
   significantly more quickly than before, until the configured
   :any:`max-cache-size` limit was reached. This has been fixed.
   :gl:`#4596`
 
-
 - Using :option:`rndc flush` inadvertently caused cache cleaning to
   become less effective. This could ultimately lead to the configured
   :any:`max-cache-size` limit being exceeded and has now been fixed.
   :gl:`#4621`
 
+- The logic for cleaning up expired cached DNS records was
+  tweaked to be more aggressive. This change helps with enforcing
+  :any:`max-cache-ttl` and :any:`max-ncache-ttl` in a timely manner.
+  :gl:`#4591`
+
+- It was possible to trigger a use-after-free assertion when the overmem cache
+  cleaning was initiated. This has been fixed. :gl:`#4595`
+
+  ISC would like to thank Jinmei Tatuya of Infoblox for bringing
+  this issue to our attention.
