While WordPress version 3.5, and subsequently 3.51, have recently been released to generally positive reviews (including my own), there is now anticipation for the next version of WP. According to the WordPress VIP site, the emphasis for WP 3.6 will be the inclusion of content editing which will focus on the editorial workflow process of editing, auto saving, and revisions.
Apparently, with version 3.6 WordPress wants to prevent users from losing their writings due to connection problems, plugin errors, browser crashes, etc. Fortunately I’ve not had a problem with this kind of stuff in the past, but in multi-user environments I can see how there may be issues. Hence, WP is also looking at implementing a locking functionality to prevent one person’s changes from being overwritten by another.
The other two significant items mentioned are improved post formats and an improved and less confusing user interface for custom menus. Check out the wordpress.com site to learn more about WP 3.6.
