DeepCube™ 1.18.27

Everything since 1.18.8 lands in this Steam update. Preferences are rebuilt from the ground up, and Tessa can read them and change some of them for you. When the frame rate gives out, the app says so and offers one click down. In the Shoebox sandbox, Tessa checks a diagram before she runs it and tells you what she assumed. Busy grids do less work every frame, and two causes of falling through the ground are fixed.

What's New

  • Preferences, rebuilt: press F9 in a grid to open them, grouped into World, Display, Effects, Assistant and Advanced. Rendering quality is a dropdown of six levels, from Ray Tracing (Realtime GI) down to Minimum. A fresh installation starts on Medium, and an existing one keeps the level it had. Reset To Defaults puts everything back in one press and lands rendering quality on Minimum, because reset is what you reach for when the app is misbehaving. It does not sign you out.
  • Tessa reads and changes your preferences: ask what a setting is set to, or ask her to change it. Rendering settings, sign-in and redaction stay yours to set.
  • One voice across clients: Tessa's voice is saved to your account, so the voice you choose here is the one you hear in DeepCube Web.
  • Frame-rate prompt: if the frame rate stays under 30 for ten seconds (after a 15-second warm-up), the app says so and offers to drop rendering quality one level. It stays quiet for five minutes after each prompt, and at Minimum it suggests using filters to show fewer blocks instead. Don't Ask Again switches it off; turn it back on under Assistant in Preferences.
  • Shoebox, checked before it runs: Tessa loads and checks your diagram first, then runs it as a separate step. She tells you what she assumed, shows you the diagram she drew when she read it from a picture, and reports loops and services nothing calls instead of redrawing them away. A share link now matches the diagram that actually ran.
  • Tessa sees what you send her: a message that is only an image now reaches her, and recent images stay in the conversation. On the Shoebox grid, paste a screenshot of an architecture diagram and ask her to run it. Anything you send to the Shoebox lands in a public sandbox, so leave out anything proprietary.
  • Ask Tessa to clear the service map and she clears it.
  • When the assistant service is starting, the chat says so once and waits. If it never comes up, you are told, and sending your message again should work.
  • Phantoms as questions: Tessa treats a phantom as a question to answer, saying what was inferred and from what evidence, rather than announcing a discovery.
  • Connections stay on the map: an idle connection thins but stays on the graph until it has had no traffic for Keep connections for (Advanced, 60 to 300 seconds, default 300), instead of disappearing within 20 seconds.
  • Lighter busy grids: blocks and the service graph do less work every frame. Tesseracts animate only when close and in view, and a platform's portal appears only when you are near it.
  • Demo screens on platforms: turn on Show demo screens on platforms (Advanced, off by default) and each service platform shows three tables filled from demo-screen-1.csv to demo-screen-3.csv in the app's Demo folder.
  • Help is rewritten, and says where to go when the frame rate drops.
  • Teleport and fall diagnostics are off by default, so the avatar does no extra work each frame. If you fall, turn them on under Advanced and teleport again.
  • Security update: a bundled component is updated to fix a high-severity vulnerability (CVE-2026-26127) that could affect the app's availability.

Fixes

  • Fixed teleporting off a moving platform carrying you with it as you left, which could drop you through the ground on arrival.
  • Fixed falling when the platform you were standing on was removed after five minutes without traffic. You are now returned to the hub.
  • Fixed a newly seen service's first traces drawing no queue or dependency nodes, and no connections between its services.
  • Fixed the chat staying blank when two copies of the app ran at once.
  • Fixed the chat waiting forever when one sentence of speech failed, and the "Thinking" indicator staying on after a failed turn.
  • Fixed the new-version prompt linking to a page that no longer exists, and the Preferences tabs scrolling sideways.

Known Issues

  • Demo mode hides only the grid's name. Hosts, URLs and database names in your telemetry are shown as your services report them, with Demo mode on or off. Check what is visible before you demo or share your screen.
  • The chat handles one conversation at a time. The transcript survives reopening the window, but is not saved between sessions.
  • An open Preferences screen does not refresh when a setting changes elsewhere, for example when Tessa changes it. Close and reopen it to see the current value.
  • If the preferences file cannot be written, a change still applies for the rest of the session but is gone after a restart, with no warning.
  • After her tools have run, Tessa's written answer can occasionally come back empty. The chat shows a short note naming what ran, but the answer itself is lost; ask again.
  • At the start of a conversation, "a shoebox of 5 microservices calling each other" can get an answer about writing code. Remind Tessa that a Shoebox is the sandbox.
  • Asking Tessa to clear the service map does not remove trace blocks.
  • On a platform you have already visited, reloading the demo screens refreshes their rows and titles only. A change to a file's columns, or a file deleted or fixed since your visit, needs an app restart to show there.
  • The fix for being carried off a platform as you teleport does not yet apply in VR.
  • macOS support is experimental and may lack full feature parity with Windows.
