2.1 - Added automatic update checking via Joomla! Updates plugin
2.0 - Added option of user defined order number pattern
1.1 - Corrected condition if the order number is four or more digits (in this case the number generated was YYYYMMDD0000NNNN)
1.0 - Initial release
1. Install Plugin
2. Configure plugin as "User defined"
3. Enter the number of "N"s corresponding to the number of digits you want in your order number. NNNNNN = 6 digit order numbers.
4. Enable the plugin.
Done. The plugin automatically starts order numbering using the natural sequence already established. We already had 318 orders on record, so this plugin numbered our next order at 000319. Sweet.
A nice non-commercial free alternative to the for-pay plugin already on the market.
