=== 2.80 ===
This versions consists of some under-the-hood changes, no functionality added. Changes are significant however.
* PPSS does not use local locking of items anymore. The central listener process is the one that requests new items and start a new worker after the previous one finished. Locking is only used when operating in distributed mode.
* Fixed issue 32: when processing large number of items, lots of memory is consumed because all items are loaded into an array. This is no longer the case. PPSS now uses 'sed' to read a particular line from an input file containing all the items. Therefore, the memory footprint of PPSS remains small.

* Major change: PPSS now generates unique file names for log files and item locks using MD5 hashes. Thus, job file names cannot be tracked back to items, but that should not be a problem. Just grep for SUCCESS or FAILURE to determine issues, or grep for the particular item, to find the actual file containing the output. * Major change: PPSS now generates unique file names for log files and item locks using MD5 hashes.
