This file contains a log of changes to the API.
API version 1.5
  Add two new alter hooks: page_manager_operations_alter and 
      page_manager_variant_operations_alter to allow modules to add tabs
      to any page manager page.

API version 1.4:
  Allow themes to provide APIs which includes default pages of all types.
  Intorduce ctools_css_add_css() to allow private file systems to have generated CSS.
  Introduce initial build of stylizer.inc to allow UI configurable styles.
  Introduce 'cache warming' feature. Use 'ctools-use-ajax-cache' or
    'ctools-use-modal-cache'. Doing so will cause content to be fetched
    via AJAX on page load and kept warm in a cache for instant responses
    to clicks.
  Generalized ctools_add_css().
  Generalized ctools_add_js().
  Generalized ctools_image_path().
  Make global hooks for plugin definition optional through a 'use hooks'
    plugin option.

API version 1.3.2:
  Introduce 'export callback' to individual fields in export.inc

API version 1.3.1:
  #649144 by neclimdul: Expand ctools_include() to work for other modules.

API version 1.3:
  Introduce ctools_jump_menu().
  Change plugins to no longer need magic function. Can now use $plugin = array(...) instead.

API version 1.2:
  Introduce ctools_set_variable_token().
  Introduce ctools_set_callback_token().
  Introduce cleanstring tool. See cleanstring.inc
  Introduce page_manager_get_current_page().
  Introduce ctools_ajax_command_redirect().
  Introduce ctools_ajax_command_reload().
  Introduce ctools_ajax_command_submit().
  Introduce ctools_static().
  Introduce ctools_modal_command_loading().

API version 1.1.1:
  Introduce ctools_plugin_get_class() and ctools_plugin_load_class()
  Introduce ctools_ajax_command_attr().
  Introduce ctools_set_page_token().

API version 1.1.0:
  delegator module destroyed, replaced by page manager. All 'task' and 'task_handler' plugins
  now owned by page_manager. Update plugin hooks accordingly. The filename for defaults
  for pages and handlers should now be MODULE.pages_default.inc

  The task_type plugin has been removed.

  Task handlers no longer have a separate UI. While task handlers can still
  be separated from pages for other purposes, they will probably need
  to implement their own UI to do it.

API version 1.0:
  Initial CTools API version.
