Release notes

Commits since last release: v25.3.0-rc.3...v25.3.0-rc.4. Changes are summarized below.

Fixes

• The logic for removing stale ComputeDomain node labels has been fixed and consolidated, which is especially important when workload pods are created and then deleted again in rapid succession (#404).
• A ComputeDomain update (an IMEX daemon Pod IP change) was not reliably leading to daemon restart (#407).
• The IMEX daemon's liveness probe's stderr was not collected (#407).
• The IMEX daemon's log output was not reliably collected, especially around shutdown (#407).
• Controller pod and IMEX daemon pods now explicitly run with NVIDIA_VISIBLE_DEVICES=void which addresses various error symptoms in some environments (#402).

Notable changes

• Container images are now based on nvcr.io/nvidia/cuda:12.9.1-base-ubi9.
