WMCore 2.4.4 production central services release
This is planned to be the last WM central services stable release for WMCore code freezing. The base image has been upgraded to Debian Trixie (bringing in a new OpenSSL and Curl/libcurl library versions).
A new workflow parameter has been added, called JobExtraMatchRequirements, which can be used to propagate extra job match-making requirements from the workflow down to the job description in HTCondor pool (note that full functionality depends on WMAgent 2.4.5+).
We have also upgraded the Harvesting PSS memory watchdog default to 3GB - in sync with runtime memory request available in WMAgent 2.4.5+. Lastly, it also allows now Extension value to be used for the workflow SubRequestType parameter.
Release date: Oct 13, 2025.
Changes since release: 2.4.3.
