v4.2 Release Notes

Acknowledgments

Breaking Changes and Deprecations

Operating System Support

  • Open OnDemand version 4.2 adds support for Debian 13 and Ubuntu 26.04.

  • Open OnDemand version 4.2 drops support for Ubuntu 22.04.

Dependency Updates

This release updates the following dependencies:

  • Passenger 6.1.2

  • NGINX 1.28.0

  • ondemand-dex 2.45.1

Ubuntu and Debian repository signing change

Debian and Ubuntu repositories are now signed using a SHA512 key rather than the previous SHA1 key.

Using the OnDemand release packages will result in the correct key being used.

If not using OnDemand's release packages, the DEB-GPG-KEY-ondemand-SHA512 should be downloaded and used by the OnDemand repository's signed-by.

curl -fsSL https://apt.osc.edu/ondemand/DEB-GPG-KEY-ondemand-SHA512 | gpg --dearmor -o /etc/apt/keyrings/ondemand-web.gpg

source /etc/os-release
echo "deb [signed-by=/etc/apt/keyrings/ondemand-web.gpg] https://apt.osc.edu/ondemand/4.2/web/apt $VERSION_CODENAME main" > /etc/apt/sources.list.d/ondemand-web.list

Behavior Changes

Active Jobs Extended Details Panel Opens to the Side

In order to make the Active Jobs table accessible to screen readers, the mechanism for viewing the extended details of a job has been changed. Instead of opening the panel inside the table, it now opens either above or beside, allowing table navigation to proceed normally.
