John Lauer What's new in 1.0.701: every feature since 1.0.666, the last public release 901ea46 9d ago

What's new in Hydrogen 1.0.701

The last public release was 1.0.666 (21 October 2026). 1.0.701 carries every insiders build since then, 35 of them. This page is the tour, grouped by what you will notice. Each item names the build that brought it, so you can find its changelog under Releases.

Setup finishes on more PCs

  • Mirrored networking that breaks no longer stops setup. WSL's mirrored networking (the default) fails on some PCs in one of two ways. Either the editor never loads at "Sign in to Adom, then activate the editor", or Windows cannot reach the workspace even though it is running. In both cases setup now switches the workspace to NAT networking once and carries on. The second case used to end on "Couldn't build the workspace image", which sent people to delete a good workspace. Now it is called what it is: a network failure. (1.0.682, 1.0.686; #145, #157)
  • NAT networking works properly. When a .wslconfig has localhostForwarding turned off, the editor cannot load on NAT, so setup turns it back on and remembers what it was. (1.0.672)
  • No false alarm about AI sign-in on NAT. Hydrogen used to warn that your AIs could not sign in on every NAT workspace. Now it tests the real sign-in trip and warns only when sign-in is actually blocked. (1.0.671)
  • The editor step waits out a restart. Setup no longer gives up when code-server restarts partway through the editor step. (1.0.689)
  • Better reports when something does go wrong. Setup now sends WSL's own error message, the network mode, why a download failed and how long a stop card was on screen. That lets us fix the problems still left in install. (1.0.677, 1.0.683)

Choose your workspace networking

Settings, Workspace networking lets you pick mirrored or NAT networking for your Linux workspace. Changing it restarts WSL. Turning IPv6 back on from the setup card also puts you back on mirrored networking. (1.0.675, 1.0.689)

WSL that hangs fixes itself

Windows' WSL service sometimes stops answering, and the workspace used to stay down until the PC was restarted. A watchdog now checks WSL once a minute. After three misses it recovers WSL without asking for admin rights, tells you it did, and reopens the AI conversations that were open. (1.0.670)

  • Links open without the picker. Hydrogen remembers which browser you chose for each website. A toast with Change lets you pick again. Shift+click on any link, including one inside a webview tab, always shows the picker. (1.0.668, 1.0.679, 1.0.682)
  • Your default browser is read correctly. Windows 11 keeps your real default browser in a newer setting. Hydrogen used to read the old one, so links could open in Edge for a Firefox user. (#156, 1.0.688)
  • The browser stays in front. After you click a link, the browser page stays on top. Hydrogen no longer pulls its own window back over it. (1.0.692, 1.0.699)

Lighter on your PC

  • Hidden means idle. A Hydrogen window that is minimized or closed to the tray stops drawing, so it no longer uses the GPU or leaks graphics memory. (1.0.674)
  • Background webview tabs pause like background tabs in a browser. They stop drawing and using CPU until you switch back. (1.0.676, 1.0.682)
  • The setup screen no longer slows down PCs without a graphics driver. It skips the animated deck when the PC can only draw it in software. (1.0.678)
  • Honest memory numbers. The RAM meter says whose memory it is. When your PC is full of other programs, that no longer reads as Hydrogen using it. The low-memory warning names only the PC's free memory and Hydrogen's own use. (1.0.668, 1.0.669)
  • Linux can stop runaway AI work started from the editor when memory runs out, instead of the whole workspace suffering. (1.0.679)

The editor keeps your place

  • Your folder comes back. The editor reopens the folder you had open last time, and recovery reloads keep it too. A strip tells you when the editor is outside your project folder, and a chip and an Adom menu item take you back. (#155, 1.0.684, 1.0.687, 1.0.689)
  • The Explorer stays closed unless you open it. It no longer pops open by itself when a folder loads or a layout is restored. When you open it yourself (Ctrl+Shift+E or its icon), it stays open. (1.0.689, 1.0.698)
  • No more recovery shield after a wake when nothing failed. A retried AI request or a background Codex request is not counted as a failure. (1.0.673)

Updating is quicker

Restart to update applies right away, and idle Claude panels no longer hold an update back. (#153, 1.0.688)

Every permission, everywhere

Hydrogen is a power-user tool, so every webview and every frame inside it now gets every browser permission: microphone, camera, clipboard and the rest, with no prompts. Apps in webview tabs can use the mic and camera straight away. Codex dictation gets the microphone too. It will show up once OpenAI ships a Codex build that offers dictation inside the editor without freezing it. (1.0.690)

Codex can't freeze the editor

One Codex build (26.1021, see openai/codex#56780) never finishes loading its panel and freezes the whole editor. Hydrogen holds that build back, so it never shows up as an update. If a Codex panel freezes anyway, Hydrogen notices within 30 seconds and stops reopening or warming Codex tabs until it restarts, so the editor does not freeze again and again. (1.0.683, 1.0.689, 1.0.696, 1.0.697)

Apps your AI builds open in a webview, even on NAT

On NAT networking, a program on Windows can already be using the port of an app your AI just built. The webview tab used to show that other program without saying so. Now it says which program owns the port and asks your AI to serve the app on a different one. (1.0.695)

Report a problem goes to the right page

Adom menu, Report a problem now asks which app the problem is with and files it on that app's page, with that bridge's logs attached. (#152, #154, 1.0.685)

For AIs driving Hydrogen

  • A prompt sent to a conversation by its id (POST /ai-threads/run-prompt with a sid) is refused straight away, naming the tabs, when two open tabs could be that conversation. It used to type into the wrong tab and hang for 40 seconds. (#142, 1.0.678, 1.0.700, 1.0.701)
  • A tab that run-prompt opened stays paired with its conversation, even when Claude Code retitles it late or another tab has the same title. (1.0.680, 1.0.693, 1.0.694)
  • EDA discovery scans every drive for KiCad, Fusion 360 and Altium. (1.0.684)
