• Multiple Workshop bugfixes with fixed/capped pricing listed below. Now fixed.
  • Price setting broken when invoice contains other items with line discounts on them.
  • Also broken for GST exempt sales
  • Also broken when trying to set a price that doesn't round to default rounding boundary.  Ignore invoice rounding for fixed/capped jobs
• Spare parts description search
  • Generally should run alot faster. Especially for big searches across all price files. i.e. searching for 'kit' or 'screw' across a million or so parts.
  • Allow description to do partial wildcard matches.  i.e. 'sunglass'  will match 'sunglasses' but 'sun*' will match anything that starts with 'sun', including 'sunset',  'sun' and 'sunglass'.
• Contacts search
  • Also optimised to run faster. Especially when there are multiple search terms.
• System level changes
  • Added new switch to disable monitors such as sms reply checking. (For software dev only).
