=== Roy Henderson ===

 * huge speed-up for ipptopsps by using multiple 'clients'. This included:
  * lots of headaches with TRANSACTIONS and LOCK TABLES to protect the critical section of the database when queuing multiple clients
  * with a mysql LOCK in place, it was necessary to speed-up a lot of my queuing queries to avoid deadlock
  * each process now stores its PID and hostname for unique log-naming
  * lots of monitoring to check things were running smoothly
  * some tricky clean-up after a screw-up before mutex was properly implemented

 * other ipptopsps development:
  * added coordinate constraints to queuing query so we can load certain regions of old 3PI data
  * datastore class now takes an ipptopsps database object to constructor so it can update the database itself
  * changes to cleanup code: now only deletes from local disk batches that have been merged

 * other:
  * duplicate exp_ids in DVO broke merge, some cleanup work with Sue was required
  * more cleanup work with Sue later in the week when DXLayer stopped and local files were deleted
  * filled up /var with mysql logs: Gavin kindly moved mysql data dir to data partition, and reduces logging retention time
  * some help getting DXLayer to start again: too many subdirs
  * changes to PSPS news page to reflect current status after the merge
=== Mark Huber ===
