[UPDATE April 28th, 2016: There are more than 200 new terms in the 5th edition of the PMBOK, and we are adding new terms every day now!]
In 2013 already, the PMI has updated the PMBOK. Please note that not all new terms have been added yet, we are working on this right now. There have been significant changes, i.e. a huge number of terms has been added and another huge number of terms has been removed. Having said that, even if some terms are officially “outdated”, they will still be used by some project managers. In some cases, project managers have been using the new terms even before they have been added to the PMBOK which clearly shows that the PMBOK is also updated to reflect the changes in reality. Please note that we try to mention in which version of the PMBOK terms are mentioned or not mentioned so that you know for which version the term is important if you are preparing for your Project Management Professional certification or any other certification the PMI is offering.
We will also update the abbreviations/acronyms.
