The reasons for this decision were numerous and include:

• The history of discussions around DSpace "2.0" has have gone through many different lists of proposed features revisions over the past 8 years:
  • Discussion of "2.0" first began in 2004, with Robert Tansley's DSpace 2.0 Original Proposal
  • A reworking of the "2.0" concept happened in 2006, during a DSpace Architectural Review.
  • A further reworking of the "2.0" concept occurred in 2008-2009 when a prototype version of DSpace 2.0 was built and demoed at Open Repositories 2009.
• As detailed in the 2.0 history above, much of the planning around a "2.0" is now many years old. Although many great ideas/concepts have come out of that work, much of it does need to be reanalyzed for the modern repository environment.
• "2.0" has always been talked about as a "revolutionary" change to the DSpace software platform. In reality, we've found that many of these the platform improvements attributed to "2.0" have been incremental in nature and have been included over many releases (for example, nearly every major release in recent years has included some . In fact, several 2.0 code/concepts (from the 2009 DSpace 2.0 Prototype) have been included in almost every recent major release.
• Because the "2.0" release has a perception of been perceived as being "revolutionary" in nature, it would be difficult to ever fully meet the expectations/assumptions that have built up around this release over time.
• We all feel that the DSpace Community's immediate needs are better met by incremental changes (over several releases) than by revolutionary changes (over a single release). We feel that incremental changes provide an easier upgrade path between current and future releases of DSpace.

Therefore, many Many of the ideas/concepts of "DSpace 2.0" may still be coming to the DSpace platform. But, they will continue to be added incrementally over several releases. The ideas behind "2.0" still live on, even while the release numbering has changed.
