+     timed out and kills him), see gh-824
    * UTF-8 fixes in pure-ftp thanks to Johannes Weberhofer. Closes gh-806.
    * systemd backend error on bad utf-8 in python3

 - Enhancements
+   * Start performance of fail2ban-client (and tests) increased, start time
+     and cpu usage rapidly reduced. Introduced a shared storage logic, to bypass
+     reading lots of config files (see gh-824).
+     Thanks to Joost Molenaar for good catch (reported gh-820).
    * Fail2ban-regex - add print-all-matched option. Closes gh-652
    * Suppress fail2ban-client warnings for non-critical config options
    * Match non "Bye Bye" disconnect messages for sshd locked account regex
