Changed the name in Multipage Plugin. Also changed the css filenames in multipage.css and multipage.min.css.
Loads default values even if never saved settings.
Added the option to hide comments on all the subpages except in the first one.
Added new options to customize the table of contents: "Hide the new TOC header", "Add a link for comments", "Show only on the first page", "Label choices", "Show before or after the content", "Hide it".
Completely rewritten part of the main code in order to improve performances.
Changed some classes name (maybe you need to correct your customized css).
The settings menu is now named "Multipage" (still under "Settings").
Now multipage posts will appear correctly in non is_single() pages even if there is no <!--more--> code.
Updated .pot file
Updated Italian (it_IT)
Updated Deutsch (de_DE)
Fixed a bug that returned, in some conditions (there is no intro title), 404 on the last page.
Now you can configure some summary appearance options. The admin menu is under "Settings".
Now returns 404 error if the requested page number doesn't exists. It works also if the requested page is 1, because the real permalink is the base one.
Updated "Tested up to" with the new WordPress 3.8.
Now you can navigate through the pages also in previews.
RTL first support.
Customized css automatic load (put your nextpage-titles.css in WordPress theme/child-theme css directory ex. /wp-content/themes/twentythirteen/css/nextpage-titles.css)
Fix a permalink bug with structures without a slash at the end.
Removed a deprecated function that in some conditions generated errors.
Definitively solved the 404 error, caused by pretty urls that are now deprecated (eventually waiting for a 2.0 working version) in favor of native page numbers. Different subpages will have now the same link of the original <!--nextpage--> code.
New Features *
Added the initial code for the configuration page (not active yet).
Correct a bug that sometimes displayed summary on loop pages.
New Features *
Possibility to give a different name to "intro", just create a nextpage title shortcode on the first line of the editor.
Version numbers, somebody couldn't update it. Now it's ok.
Quite completely rewritten! now uses the internal core of WordPress nextpage original code.
Unfortunately I had to modify the subpage pretty link for permalinks due to conflicts with attachment pages, now subpages have 'subpage-' prefix.
Now works with all post_types, anyway pretty url works only on "post".
