-This api can be called to change the format of the `log_conn_id` fields to a 17 Char varchar - and to switch to using truly unique connection ids. Calling this api can also convert log tables to INNODB - using this hook [hook_civicrm_alterLogTables](/hook/hook_civicrm_alterLogTables) either in your code or with the [Extension](https://github.com/eileenmcnaughton/nz.co.fuzion.innodbtriggers/blob/master/innodbtriggers.php)

 Note that log table conversion can be slow which is why we are offering a conversion tool for the improved `log_conn_id` storage rather than springing it in an upgrade script

 ### 4.6.0: CRM_Contact_Form_Search_Interface->buildTaskList
 
 Classes which implement this interface must implement a new method called buildTaskList. This method is responsible for building the list of actions (e.g., Add to Group) that may be performed on set of search results. It differs
-from [hook_civicrm_searchTasks](/hook/hook_civicrm_searchTasks) in that the hook allows a developer to specify tasks by entity (e.g., Contact, Event, etc.) whereas buildTaskList provides the ability to target a specific form. The new method takes a `CRM_Core_Form_Search` object as an argument and should return an array. Dump `CRM_Core_Form_Search()->_taskList` to learn about the format of the array. The array returned by buildTaskList will completely replace the task list.

 Aside from the community-maintained custom searches in `CRM/Contact/Form/Search/Custom/`, this change does not affect CiviCRM core. Custom searches which extend `CRM_Contact_Form_Search_Custom_Base` (as do those built on civix) will not be affected, as the method is implemented there.
