+ - Enhancements:
++   * Extreme speedup of all sqlite database operations (gh-1436),
++     by using of following sqlite options:
++     - (synchronous = OFF) write data through OS without syncing
++     - (journal_mode = MEMORY) use memory for the transaction logging
++     - (temp_store = MEMORY) temporary tables and indices are kept in memory
+    * action.d/cloudflare.conf - improved documentation on how to allow
+      multiple CF accounts, and jail.conf got new compound action
+      definition action_cf_mwl to submit cloudflare report.
