Version 7.4.5 [v7.4-stable] 2013-10-22

• mmanon: removed the check for specific “terminator characters” after
  last octet. As it turned out, this didn’t work in practice as there
  was an enormous set of potential terminator chars — so removing
  them was the best thing to do. Note that this may change behaviour of
  existing installations. Yet, we still consider this an important
  bugfix, that should be applied to the stable branch.

  Thanks to Muri Cicanor for initiating the discussion
• now requires libestr 0.1.8 as early versions had a nasty bug in
  string comparisons
• omelasticsearch: add failed.httprequests stats counter
• bugfix: invalid property filter was not properly disabled in ruleset
  Note that this bugfix introduces a very slight memory leak, which is
  cosmetic, as it just holds data until termination that is no longer
  needed. It is just the part of the config that was invalid. We will
  “fix” this “issue” in the devel version first, as the fix is a bit
  too intrusive to do without hard need in the stable version.
• bugfix: segfault if re_extract() function was used and no match found
• bugfix: potential misadressing on startup if property-filter was used
  This could happen if the property name was longer than 127 chars, a case
  that would not happen in practice.
• bugfix: omelasticsearch: correct failed.http stats counter
• bugfix: omelasticsearch: did not correctly initialize stats counters
• bugfix: omelasticsearch: failed.es counter was only maintained in bulk mode
  This usually did not lead to any problems, because they are in static
  memory, which is initialized to zero by the OS when the plugin is
  loaded. But it may cause problems especially on systems that do not
  support atomic instructions – in this case the associated mutexes also
  did not get properly initialized.
• bugfix: mmanon did not detect all IP addresses in rewrite mode
  The problem occured if two IPs were close to each other and the first one
  was shrunk.

  Thanks to micah-at-riseup.net for reporting this bug
• bugfix: mmanon sometimes used invalid replacement char in simple mode
  depending on configuration sequence, the replacement character was set
  to ‘s’ instead of the correct value. Most importantly, it was set to
  ‘s’ if simple mode was selected and no replacement char set.
