Given that Unicode has declared mid-year annual major releases, we can expect Unicode Version 8.0 to be released in about a year, in mid-2015. In terms of ideographs, we can expect some additions, specifically a small number of UNC (Urgently Needed Character) additions to the URO (Unified Repertoire & Ordering) that were discussed in the June article, along with Extension E. This single-page PDF provides a tentative look at the CJK Unified Ideographs, along with CJK Compatibility Ideographs for good measure.
Unicode Version 7.0 was release on June 16, 2014.
