Dec 1, 2025

Monthly summary for 2025-12 focusing on theforeman/foreman: Delivered a key provisioning enhancement and bug fix enabling robust image-based provisioning through improved parameter handling. The Provisioning System now renders transient host parameters via the host_param macro, ensuring all host parameters (not just those in the database) are applied in templates and orchestration actions. This unblocks image-based provisioning scenarios where activation keys are defined at the host level rather than the hostgroup, reducing provisioning failures and manual work. The change updates template rendering in hosts#template_used and the Orchestration::Templates queue to include all host parameters. Commit: d61cf5adbd4fe67fb09f1151f2fa5a5c2d2f1810 (Fixes #38939).
