 From the committers' point of view, it makes perfect sense for 3.0 to 
be the culmination of the 2.x releases, but I'm not sure the users 
understand this as well, so I'm extending the question to the users list.

Traditionally, proprietary software is developed behind the curtains, 
and it's normal to have one big release every two years, with lots of 
new features and some bugs which get fixed in subsequent bugfix 
releases. Marketing comes mostly from the proprietary software world, so 
from a marketing point of view, this is the "normal" way releases work.

In the open source world, since the development is done in the open, it 
doesn't make sense to stash code away in a repository and only release 
it once every two years. Still, most big projects use a release 
versioning scheme similar to the proprietary products, but with a slight 
difference which deeply changes the meaning. While proprietary products 
use only a number (3, 8, 2010...), with eventual bugfixes versions (SP2, 
5.5), open source usually has 3 numbers in its versions, with the 
following meanings:

The first number changes rarely, and when it does, it signals a critical 
change, like a complete rewrite of the codebase, a change of paradigm, 
or major new features. The second number is the one that actually 
identifies a release. The third number is the bugfix version. So, when 
we say that PHP 5.3.2 was released, we actually say that version 3 of 
PHP5, which is a different thing than PHP4, has been released again, 
giving the second bugfix release. KDE 4.5.1 means version 5 of KDE4 saw 
its first bugfix release.

Another tendency is for open source software to linger towards a major 
release. For example, lots of software have a lot of releases before 
1.0, going nearer and nearer: 0.6, 0.9, 0.9.9... And everybody knows 
that 0.x comes before 1.0, and it's not just a bugfix version of an 
imaginary 0.0 release.

A different topic is that of agile development, with very short releases 
(2-3 weeks) for which traditional version number make no sense, since 
such a product would reach version 42 in a couple of years. Either an 
identifier, such as the SCM version number is used, or a continuous 
counter (v1.42) is used. Since the software evolves in a fluid manner, 
without a "breakthrough" version coming out of the regular releases, a 
"major" version is released when the current features are stable and 
they mix well together in a coherent product. Since releases come so 
frequently, it's normal for users to be split into two categories: those 
that follow the releases and know how the software is evolving, and 
those that only monitor the major releases, and which see all the 
continuous improvements at once.

While XWiki Enterprise is used in the enterprise environment, and it is 
backed by commercial companies, it is a true open source project, 
following an open source release model, so I don't think that a 
proprietary product release scheme is suited.

Our development/release style is closer to the agile development 
practice, albeit with mixed release types. In the future, once the core 
is more stable than it is now, we'd like to move even closer to a full 
agile release process, with 2-3 weeks between final releases. Thus, I 
believe that the last release versioning strategy is the best for XWiki 

Note that we're already using this strategy in a more obvious way for 
smaller modules (applications, skins, tools), where we do have 1.32 as a 
stable version number.

Also note that although 1.9 was followed by 2.0, this was just a 
coincidence, and not a natural version evolution, since we also felt 
that the code was mature enough to receive a major number bump, but it 
could just as well have been followed by a 1.10.

So, there are two different opinions here. One that 3.0 should present 
the groundwork/roadmap for the following 3.x releases, and one that 3.0 
should be the culmination of the work done so far on the 2.x releases.

The committers (with the exception of Ludovic) believe that the latter 
is the better one, and it is in accordance with what we've been doing so 
far. What do our users think?

As a final remark, the XWiki Open Source projects are governed by the 
committers, so in the end the decision lies in the hands of the 
developers, but we're always open to the larger community. If no 
consensus is reached about when to release 3.0, we will continue 
releasing 2.x versions.

What do XWiki users think? Is 3.0 as a culmination of the 2.x releases, 
with no major new features besides what 2.5 already provides, something 
the community expects?

XWiki SAS is in the Gartner report, as a vendor. The XWiki Enterprise 
project is not in that report. I think the marketing direction that 
Gregory and Ludovic are supporting is better suited for the company

Yes, these should be central in the future 3.x releases, but not in 3.0, 
which should be as stable as possible, without any "demo" features.
