Recent updates to the OED
The OED is updated four times a year, every March, June, September, and December.
The material added to the dictionary includes revised versions of existing entries (which replace the older versions), and new words and senses both within the alphabetical sequence of revised entries and also across the whole A to Z range.
Published quarterly since 2000, the updates make up the Third Edition of the OED.
June 2013 update
The latest range of revised and updated OED entries focuses on the revision of three words – hand, head, and heart – covering 2,875 headwords, compounds, and other expressions including a head for business, handyman special, and heart-wrenching.
Alongside these there are key new additions and revisions from the spheres of technology, popular culture, and current affairs: dad dancing, epic, fiscal cliff, flash mob, follow, geekery, pay day lending, the silent treatment, and tweet.
You can read more about the revisions and new words in the June 2013 update in this article by the Chief Editor of the OED, John Simpson.
