| 5 | 5 | * (trunk) -- Version 2.0rc3 alpha |
| 6 | 6 | - Adjusted to work with 'Regex Fun' version 1.1 |
| | 7 | + - '{{#arraydefine: a |}}' will create an empty array instead of an array with an empty element as in |
| | 8 | + version 1.3.2. A new option 'singleempty' can be used to avoid this behavior, ',' can be used to |
| | 9 | + create an array with two empty elements. |

| 8 | 11 | * December 5, 2011 -- Version 2.0rc2 |
| 9 | 12 | - Bug introduced in r105069 fixed where '#arrayprint' was broken in compatibility mode in some cases. |
