Upgrading from News Manager 3.0 to 3.1 should not have any problem - just copy/upload the whole plugin (news_manager.php and news_manager folder with its contents, overwriting all files) over your current installation.

There are, however, a few changes you should know before upgrading:

  • Tag pages are now included in the Sitemap by default. If you don't want this to happen, enable NMSITEMAPEXCLUDETAGS in gsconfig.php

  • Tag pages now have the tag name inserted in the <title> tag (for better SEO, like single post pages). If for whatever reason you want to avoid this, enter tag titleTag 0 in Custom Settings.

  • The older/newer page navigation now uses <span> instead of <div> for the "older posts" and "newer posts" elements. If this change is an issue for your site, enter markupNavItem div in Custom Settings.
