Still To Recheck
- Confirm that the download page, release notes status, and meta-release upgrade prompts all point to the final release.
- 26.04.1 was released on August 27, 2026 (image kernel 7.0.0-30, Mesa 26.0.8); the automatic upgrade prompt for 24.04 LTS is expected in early September 2026.
- Server-focused documents still need page-by-page verification for database, Docker/Kubernetes, Nginx/Apache, Samba, OpenStack, and related version details.
- NVIDIA/AMD AI compute stacks need continued validation against the CUDA, ROCm, PyTorch, and TensorFlow support matrices.
