CloudDock Universal Usagi 4.1 Beta 5

4.1.5 is a security-first upgrade — stronger hardening, vulnerability fixes, and a Training Center that finally gets ETA + charts right, even for fast jobs.

Usagi 4.1.5 says: “You think you know what you want? No. I know you better.”

Overview

Usagi 4.1 Beta 5 (4.1.5) is built around two priorities: security and predictable workflow comfort. This release significantly strengthens system security and patches vulnerabilities. On the user side, Training Center and Launcher become more “aware”: you can see ETA + % where you actually need it — in the browser tab title, and from the Launcher.

Training Center 4.1.5 overview
4.1.5 — security hardening + better ETA/% visibility, end-to-end.

Highlights

  • Major security hardening: improved system security + vulnerability fixes.
  • Training Center tab title ETA/%: progress shows right on the browser tab (no babysitting).
  • Fast-job ETA + chart bug fixed: quick runs no longer break ETA calculation or chart rendering.
  • Launcher sees Training Center ETA/%: Launcher can display the current training job’s progress at a glance.
  • One-click venv cleanup: Training Center adds a fast “clean venv” button for recovery and maintenance.
  • Remaining-time safeguard: if you have < 15 minutes left, clicking Start training triggers a confirmation dialog.
  • Expanded Tips library: new failure patterns and fixes added (quietly, but very useful).
  • Optional: refreshed skins for Training Center / App Store / Launcher.
What 4.1.5 feels like:
Less attack surface. Less guessing. Less “why is ETA NaN?” moments.
And when something goes weird: one-click cleanup gets you back on track.

Security first — stronger hardening + vulnerability fixes

4.1.5 significantly improves system security and patches security vulnerabilities. The goal is simple: make the container ecosystem safer by default, and reduce the chance that “one bad session” can compromise the environment.

Note:
Security fixes are intentionally described at a high level in public docs.
What matters to users: stronger safety, same workflow.

Training Center: tab title ETA + % (always visible)

Training often runs in the background while you multitask. In 4.1.5, Training Center can display ETA + % directly in the browser tab title. That means you can check progress without opening the page or digging through logs.

Tab title ETA and percent
Tab title shows progress: “35% ETA: 1:00:00 — SD Training Center”.

Fast-job ETA + chart rendering — fixed

A real pain point: some fast jobs (high it/s) used to confuse the UI — ETA could fail to compute and charts could fail to render. In 4.1.5, the Training Center is more robust: ETA and charts work consistently, even when jobs move quickly.

ETA stability improvement
ETA stays stable even when training steps fly.
Chart rendering fix
Charts render correctly for fast jobs (no more blank wall).

Launcher: see Training Center ETA + % at a glance

4.1.5 connects the ecosystem tighter: the CloudDock Launcher can display the current Training Center job’s ETA + % — so you don’t have to jump back and forth just to know what’s happening.

Remaining-time safeguard (15-minute confirmation)

Training is not a “click and pray” workflow — it needs enough session time to finish cleanly. In 4.1.5, Training Center adds a simple but powerful guard: if your session has less than 15 minutes remaining, clicking Start training will trigger a confirmation dialog.

  • Goal: prevent accidental starts that will be cut off mid-run.
  • Behavior: under 15 minutes → show confirm → user can cancel or proceed knowingly.
  • Best practice: extend your session first (if available), then start training.

One-click venv cleanup — fast recovery

Sometimes training environments get messy: cached states, or half-installed packages. 4.1.5 adds a one-click venv cleanup feature in Training Center — designed for quick recovery and “I want a clean slate now” moments.

Heads-up:
This is a recovery tool. Use it when you need a clean environment or troubleshooting reset.

Tips library expanded (quiet but powerful)

The Tips library has been expanded with new failure patterns and fixes. You’ll see more “actionable answers” when jobs fail — less raw logs, more next steps.

Optional: refreshed skins

Training Center / App Store / Launcher received a visual refresh in 4.1.5. It’s optional to mention, but if you do: call it a “skin update” — the real value is the behavior.

Positioning

  • 4.1.3: Central Scheduler — close the tab, it still runs.
  • 4.1.4: Speed + Debug UX — xFormers + failed job tips.
  • 4.1.5: Security + Predictability — hardened system + ETA everywhere + fast-job fixes + one-click recovery + time guard.
