This files describes API changes in /availability/*. The information here is intended only for developers. === 3.11.4 === * There were existing restrictions on what condition plugins can do in the get_description method (for example they mustn't call format_string), which were not well documented. New functions description_cm_name(), description_format_string(), description_callback() can be used so that condition plugins to behave correctly in all situations. === 3.2 === * Condition plugins must replace the CSS selector "#fitem_id_availabilityconditionsjson" with ".availability-field". This selector is often used in your plugin's yui/src/form/js/form.js file. === 2.9 === * Condition plugins can now implement a new include_after_restore function to indicate that they should be removed during the restore process. (This is implemented so that group and grouping conditions are removed if groups are not restored.) === 2.8 === * There is a new API function in the info_module/info_section objects (and related functions in internal API): get_user_list_sql. This returns SQL code that does roughly the same as filter_user_list to return a list of users who should be shown as having access to the module or section. * Any third-party availability plugins which return true to is_applied_to_user_lists (and therefore previously implemented filter_user_list) should now also implement get_user_list_sql. If not implemented, a debugging warning will occur when anybody calls get_user_list_sql if the affected plugin is in use, and that user list will not be filtered by the plugin.
