Will there be a uP 2.6?

  • Are there incremental improvements that could be made beyond uP 2.5 that would make you want to deploy 2.6?

  • So much so that there are developers, resources interested in working to make this happen?

  • Then it makes sense to produce uP 2.6.

2.6.0


Some uP 2.6 ideas

  • Continue to improve Layout Management

  • Stability, Stability, Stability

  • Have we stopped leaking memory yet?

  • Skinning improvements, CSS/Divs as default example

  • Groups and Permissions

  • More Spring

2.6.0


Serializable Sessions

  • And sessions worth serializing

  • Beyond load balancing and clustering

    • State-retaining failover *

  • (For channels written to take advantage)

  • Wait, not just in HEAD…


Some features can be accommodated conservatively

JIRA for project planning

  • Identify desired improvements

  • Schedule for 2.6

  • “Assign” resources

  • Track to completion

2.6.0


Lather, Rinse, Repeat

  • Continue to incrementally improve uPortal 2.x so long as there’s interest and resources.

At some point

  • Interest in continuing to develop uP 2.x wanes

  • Because there’s something better to work on

  • Move what we need into uP 3

  • And now, for uPortal 3 roadmap…
