- Important: Major improvements in RSS feeds (yoursite.com/feed). Many new item fields added.
  RSS feed can now be disabled as well. When disabled, page returns 404.
  New hooks and filters created to support flexibility of data in RSS feed.
- Important: Logic for collecting listing statistics has changed. Now, only 1 stat counts towards 1 user session.
  This change applies to all "stats", including item views, premium views and reported stats (spam, misclassified, duplicated, expired, offensive).
  Why? 2 reasons: a) item & premium views were very unaccurate, b) this helps to significantly decrease database load caused by spam bots hitting all possible links, including "mark as...".
- Important: Big update with item_form and item_edit hooks, those now support different variants (ie. item_form_top), that allows to customize publish/edit page.
  Plugin now can use custom variants of hooks and show data based on category selection on numerous places (ie. below category, blow description etc.).

  Language settings were also split into several sections.
- New setting available: max category levels (nesting) - it is possible to set how many subcategories your Osclass will support.
