 - Fixes:
-
+   * [grave] memory leak's fixed (gh-1277, gh-1234)
+   * tricky bug fix: last position of log file will be never retrieved (gh-795),
+     because of CASCADE all log entries will be deleted from logs table together with jail, 
+     if used "INSERT OR REPLACE" statement
+   * asyncserver (asyncore) code fixed and test cases repaired (again gh-161)
+   * testSocket: sporadical bug repaired - wait for server thread starts a socket (listener)
+   * testExecuteTimeoutWithNastyChildren: sporadical bug repaired - wait for pid file inside bash,
+     kill tree in any case (gh-1155)

 - Enhancements:
+   * huge increasing of fail2ban performance and especially test-cases performance (see gh-1109)
+   * datedetector: in-place reordering using hits and last used time: 
+     matchTime, template list etc. rewritten because of performance degradation
+   * prevent out of memory situation if many IP's makes extremely many failures (maxEntries)
+   * introduced string to seconds (str2seconds) for configuration entries with time,
+     use `1h` instead of `3600`, `1d` instead of `86400`, etc
+   * seekToTime - prevent completely read of big files first time (after start of service), 
+     initial seek to start time using half-interval search algorithm (see issue gh-795)
+   * ticket and some other modules prepared to easy merge with newest version of 'ban-time-incr'
+   * cache dnsToIp, ipToName to prevent long wait during retrieving of ip/name,
+     especially for wrong dns or lazy dns-system
+   * FailManager memory-optimization: increases performance, 
+     prevents memory leakage, because don't copy failures list on some operations
+   * fail2ban-testcases - new options introduced:
+     - `-f`, `--fast` to decrease wait intervals, avoid passive waiting, and skip
+       few very slow test cases (implied memory database, see `-m` and no gamin tests `-g`)
+     - `-g`, `--no-gamin` to prevent running of tests that require the gamin (slow)
+     - `-m`, `--memory-db` - run database tests using memory instead of file
+     - `-i`, `--ignore` - negate [regexps] filter to ignore tests matched specified regexps
+   * background servicing: prevents memory leak on some platforms/python versions, using forced GC
+     in periodic intervals (latency and threshold)
+   * executeCmd partially moved from action to new module utils
    * several functionality of class `DNSUtils` moved to new class `IPAddr`, 
      both classes moved to new module `ipdns`
    * pseudo-conditional section introduced, for conditional substitution resp.
