SAMigo 2.4, which is in QA now along with the rest of Sakai. Improvements, new features, and future plans are noted below.

Colleagues from five other schools joined Stanford to contribute code to the Samigo 2.4 release, including new features, performance enhancements, and, of course, bug fixes. In addition to the Stanford team, contributors to Samigo 2.4 include: Lisa Wilson and James Renfro, UC Davis, Dave Ross, Albany Medical College, Joshua Ryan, Arizona State, and Diego del Blanco Orobitg and Raul Mengod, Universidad Politécnica de Valencia. A gold star goes to Stephen Marquard, University of Cape Town for his analysis, testing and advice. Notes below highlight the changes and contributions.

We really appreciate all the people who have helped with QA in past releases. Now that we are in QA for version 2.4, with many new features and improvements, again we ask the community to help. Please respond to Megan May's call for participation.

  • performance enhancements / bug fixes

Performance improvement:

Samigo's stability and performance continue to be the top goal and continue to improve, and this release includes many improvements. In particular, a few noteworthy additions are:

  • Indexes provided by Raul and Diego
  • SAK-7454: Objects were being saved redundantly and causing deadlocks. Stephen reported this during his loadtest and helped validate our fixes.
  • Optimization on the Scores page to eliminate unnecessary database writes

Bug fixes aren't listed here but can be found in Jira.

Unicon will join the Stanford team to work with Linda Place, the maven of performance and load testing at the University of Michigan, and her team, who have graciously offered to do a thorough load test of Samigo 2.4. We'll update you as the analysis progresses.

Future plans:

After the release of 2.4, the load testing is our next big milestone. The outcome of this process will inform the 2.5 release.

Ideas for features and extensions continue to pour in, and we would look forward to planning the roadmap with the community. We'll begin by working with the upcoming Sakai requirements process. The Sakai requirements team will solicit community requirements for the entire product, including Samigo, this spring. Once this process is complete, we will work with the requirements team to analyze the results relating to assessment. We plan to host an assessment summit for contributors to work together on the roadmap for upcoming effort, likely during the summer.

I'll be in touch again to update you about the plans for Samigo 2.5 and the upcoming assessment summit.
