This release implements a enhancement request to have the post define the parent category for the sub-category list. The first category of the post (the first post is used if more than one are displayed, for example on an archive page) as a parent category. If this category has no sub-categories then the widget is not displayed at all.
You’ll also notice that the exclude categories option is now a multi-selection list (use ctrl click to select more than one category).
The release also improved sanitation and validation of widget input.
This release of This Day In History sees a complete overhaul of the administration screens. This fixes a pagination bug with WordPress 4.0, adds screen options so you can choose the number of rows to show and also hide columns you don’t want, adds a basic toolbar to the name field to make it easy to at formatting and links, a changed style to fit in with the new WordPress dashboard, the plugin options page has been redesigned and a link added to the plugin screen so it can be more easily found, oh and the widget code has been updated to the latest standard and the options screen tidied a little.
This release adds a requested enhancement for the ability to display the list as a drop-down list (in the same was as the default Categories widget does). I also tidied up the widget code a bit and the widget option screen as well. Finally the plugin is now fully translation ready.
This is the first production release. It has two enhancements, Firstly you can customise the message that is displayed when there are no events (under Settings -> This Day In History) and secondly there is a new parameter for the shortcode (show-all) that you can use to show all the events that you have added. These enhancements are both user requests.
