  * Check user for permissions when inserting data. Only authentication was 
    checked, not if the user had 'insert' privileges. (issue #16)
    
  * Minor performance updates by creating macros for frequently used
    functions. (see issue #17 for more info)
    
  * Store reference counter for a series object in an uint32_t. This solves 
    a bug on big endian systems. (issue #18)
    
  * Remove server_id and idx_tp from series object and set those as flags.
    This removed the unneeded pads and saves 8 bytes for each series object.
    
  * Honor ip_support setting when sending a dns request. (issue #19)
  
  * Fixed a bug in listing and counting servers when using one of the 
    properties 'sync_progress' or 'reindex_progress'. 
    (reported by Koos Joosten, issue #20)
    
  * Fixed a bug when a select query is using a greater start time than end
    time. Instead of trying to answer to the query we now respond with an 
    error informing the user the given query is not allowed. 
    (reported by Koos Joosten, issue #21) 
    
  * Fixed typo in log message.
  
  * Fixed bug in median (and median_low, median_high) when applying on a large
    data set. (reported by Koos Joosten, issue #22)
    
  * Improve median, median_high and median_low algorithm. (see issue #23)
  
  * Fixed bug in 'drop series' statement. (reported by Koos Joosten, issue #24)
  
  * Fixed bug in creating a new replica. Possible data loss could occur when
    creating a new replica. (see issue #25)
    
  * Fixed bug in dropping items from the internal compact tree.
