The newly established DSpace Development Fund supports the development of new features prioritized by DSpace Governance. For a list of planned features see the fund wiki page.

Version 3.0

A More Recent 3.x Release Exists: DSpace 3.2

We recommend users upgrade to DSpace 3.2 directly, rather than upgrading to 3.0.  The process to do so is documented at: DSpace Release 3.2 Notes

DSpace 3.0 was officially released to the public on November 30, 2012.

DSpace 3.0 can be downloaded immediately at either of the following locations:

Why 3.0? What happened to 2.0?

In 2011, after much discussion, the DSpace Committers in conjunction with members of the DSpace Community Advistory Team (DCAT) decided to forgo releasing a "DSpace 2.0".

The reasons for this decision were numerous and include:

  • The discussions around DSpace "2.0" have gone through many different 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 the platform improvements attributed to "2.0" have been incremental in nature. 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 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.
  • 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.

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.

DSpace has changed its release numbering scheme

With DSpace 3.0, the DSpace Developers will be changing our release numbering scheme. Release numbers will now only consist of two numbers: [major].[minor] (e.g. 3.0, 3.1, 4.0):

  • Major Releases: incrementing the first number ('major') will represent a new MAJOR release of DSpace. A major release may include any or all of the following
    • new features
    • system improvements
    • architectural changes
    • bug fixes 
    • (All major releases end in ".0", so "3.0", "4.0", and "5.0" would all represent major releases.)
  • Minor (Bug-Fix) Releases: incrementing the second number ('minor') will represent a new MINOR release of DSpace. A minor release will only include
    • bug fixes to an existing major release (For example, "3.1" and "3.2" would represent two minor releases which only include bug fixes to the "3.0" major release.)

There will be a migration path for users upgrading from v1.8.2 to the 3.0 release.

3.0 Decisions To Be Documented

  • Where should translations of individual modules like Discovery go? Including them in the main messages.xml currently works. This should be answered before freeze time, it already poses another barrier for commiting of translations, see DS-1049, DS-1054. This is a subproblem of i18n Improvements Proposal, but let us not divert this discussion too much to broad topics. ~~helix84
