Prerelease 0.9.1
Version 0.9.1
* The fiels “alias_visible” has been added to ddTools::$documentFields (MODX 1.0.12).
* Be advised! The 1.0.12 version of MODX is required.
Merge branch 'master' into develop
* The array “ddTools::$tables” with its elements is declared directly in the class to make it clear.
* The field “alias_visible” will be added to ddTools::$documentFields only if the version of MODX is later than 1.0.11 for backward compatibility.
* The method “ddTools::unfoldArray” has been added. Converts a multidimensional array into an one-dimensional one joining the keys with '.' (see the description & examples).
Prerelease 0.10
Version 0.10
* Small changes for compatibility with old MODX versions.
+ The method “ddTools::sort2dArray” has been added. It sorts 2-dimensional array by multiple columns (like in SQL) using Hoare's method, also referred to as quicksort. The sorting is stable.
* Bugfix: the method “ddTools::unfoldArray” didn't used to be static.
Prerelease 0.11
