MirethSpace 0.4.2 · The Control release · See how full each agent's memory is, jump to the pane that needs you, and merge a pull request from the app

October 19, 2026

  • A context meter on every agent. Each Claude pane's title bar shows how full its memory is, so you can see an agent getting close to a compaction before it happens. It turns orange at 80 percent, and rides the Claude limits and context switch.
  • Jump to the pane that needs you. Press Ctrl+Shift+J to go straight to the next pane waiting on you, across every tab, so you never scan a grid of terminals for the one with a question.
  • Merge a pull request from the app. When checks pass, a Merge button appears in the PR chip. Two clicks to merge, and it remembers your squash, merge or rebase choice. It holds back while checks cannot be read, and reads a merge queue as queued.
  • Keep your agent CLIs current. Settings shows the version of each agent CLI and an Update all button that runs the update for you in a fresh pane.
  • Smaller touches. Open a folder straight from the empty file panel into a new tab, and a heads-up in Settings when Windows has notifications turned off.

MirethSpace 0.4.1 · The Agents release · Know when every agent is done or needs you, queue your next message, and undo any turn

October 1, 2026

  • Know when an agent needs you. Claude Code and Codex panes show their real state, read from the agents themselves: Working, Your turn, Needs your approval, Has a question, or Stopped with an error. You see it in the pane header, the Sessions list and the new Activity tab. A Claude you start by typing claude in a terminal is picked up too.
  • Pop-ups that never steal your keyboard. A small note in the corner says when an agent needs you or finishes, with a Jump button. Clicking a desktop alert opens that agent's pane, and the taskbar (the dock on Mac) shows how many agents are waiting on you.
  • Queue a message. Type your next instruction while an agent is busy. It goes in the moment Claude Code, Codex or the Mireth CLI is free.
  • Review and undo. See what every agent changed, one row per turn, even when it works straight in your project folder. Undo a single turn, and Redo it if you change your mind.
  • Pi joins the agent list. The Agents tab shows which agent programs are installed, with a Model and Effort picker, and a missing one shows how to install it instead of an error.
  • The GitHub loop. A branch chip with Pull and a proper commit window, Create PR from the app, a checks light on the pane, and Fix with agent, which hands a failed check or review comments to an agent. It uses your own gh sign-in.
  • Usage limits in the title bar. See how much of your Codex plan you have used and, if you switch it on, Claude's 5-hour and weekly limits, side by side.
  • Terminal colors. Pick a color set such as One Dark, Dracula, Nord or Solarized, or your own text, cursor and highlight colors. It works under Glass too, where the terminals stay see-through. The font list shows the code fonts on your computer.
  • Terminal extras. Ctrl+click a file path to open it at that line, right-click a pane to copy, paste or send text to another agent, and open a pane's folder in VS Code or Cursor. Fleet is now called Agents and Mail is now Activity.

MirethSpace 0.4.0 · The Model release · Every OpenRouter model, free models that never train on your code, and keys you can save right from the list

September 28, 2026

  • Every OpenRouter model. In the Mireth Harness, /model openrouter now lists every OpenRouter model that can run an agent, 375 today, with the hand-picked ones at the top. It works before you have saved a key, so you can look before you sign up.
  • Free models you can trust with your code. A model is marked free only when it is good at agent work and does not use your prompts for training: Qwen3.8 27B, Dots 3 Note and North Mini Code on OpenRouter, three models on Ollama Cloud's free plan, six on Vercel AI Gateway's monthly free credit, and Mistral Medium 3.5 once you switch its training setting off.
  • Two new providers. Ollama Cloud, which never trains on your prompts and lists all of its models before you add a key, and Vercel AI Gateway.
  • Save a key where you need it. A provider that still needs a key ends its model list with a row to save one. Paste it there, it stays hidden, and the list opens ready to use.
  • Current models throughout, including Claude Opus 5.5, Grok 4.7, Gemini 3.8 Flash and GLM 5.3.
  • Run /update in the Mireth Harness to get all of this.

MirethSpace 0.3.8 · The Glass release, properly · Your own picture behind the work, panels you can actually see through, and a workspace you can arrange

September 24, 2026

  • Your own background. Choose a photo, or a short looping video, to sit behind the app under either Glass template. Two sliders say how dark it reads and how frosted the panels look, and there are twelve glass tints if you would rather colour the glass than use a picture of your own. A video plays quietly, loops without a jump, and pauses itself whenever the window is not on screen so it costs you nothing in the background.
  • Glass that is actually see-through. The panels no longer paint a blurred copy of your picture over themselves, which is what made them read as fog. They paint nothing at all, so the one picture behind the app shows through them sharply, and each pane is lit along its edge so it still reads as a pane of glass sitting on the scene. This is the same on Windows and on Mac, because it no longer depends on the window trick that never worked on macOS.
  • Text that stays readable over anything. How dark the terminal sits behind its own text is measured from the brightest parts of your picture, so a night scene stays clear and open while a bright one gets exactly as much help as it needs.
  • Arrange your panes. Fill the whole tab with one pane from a button in its header, or by double-clicking the header, and put it back the same way. Organize tidies the rows so five panes sit three over two instead of leaving a hole. Save a named layout and come back to it later. Drag a pane by its header onto another to swap them, drag the divider between two panes to resize, and minimise a pane to a tray while whatever it is running keeps going.
  • Motion. A new setting under Theme caps how many frames a second the app asks for, with a button that measures what your display is really delivering and tells you in plain words. Useful on a fast screen, where asking for fewer, steadier frames can look smoother than chasing the refresh rate.
  • Interface size. A slider for how large the app's own text and buttons are drawn, separate from the terminal font.
  • Plug-ins are easier to find. The page is now called Plugins (MCP) and sits with the other settings about how your agents run, rather than last in the list.
  • A tidier home screen and a new app icon drawn from the Mireth crest.
  • Mireth Harness (run /update). A session that has finished no longer leaves its pane looking like it is still waiting on you. Reading or searching a file such as CLAUDE.md no longer asks for approval every time; only changing one does, and a command that quietly appends to one is now caught as well.

MirethSpace 0.3.7 · The Inbox release · Every agent in one list, plug-ins in Settings, and a steadier terminal

September 22, 2026

  • Sessions. A new list at the top of the right rail shows every agent you start from MirethSpace, in every tab, the ones waiting on you first, with how long each has waited. A count on its icon, and on the Rail button when the rail is closed, tells you someone is waiting. When the Mireth Harness asks a simple yes or no, answer it right there without leaving what you are doing. Anything else has an Open button that takes you straight to that agent. Agents from other tools are listed too, marked "we think", because their status is read from their screen. Run /update in the Mireth Harness to get the answer buttons.
  • Plugins in Settings. See the Mireth Harness's MCP plug-ins, including ones that run over the web, switch them on and off, add one from a small form or by pasting a whole command line, and remove one, with no settings file to edit. Paths with spaces work, in double or single quotes, or copied from Mac Terminal with backslashes.
  • When MirethSpace merges an agent's work, changes worktrees or cleans up branches in a project, those steps now take turns, so one no longer fails because another was running at the same moment.
  • Terminals work on a fresh Windows PC, where scripts come switched off. Command blocks, pane status, and agents installed through npm all start as they should.
  • Closing things is kinder to your work. Closing a tab asks whenever a pane in it would lose work, and going Home really closes the old tabs instead of bringing them back.
  • Smaller fixes. Ctrl+R searches your command history again. A prompt with curly quotes pasted from a document reaches the agent whole. On a Mac, hidden files such as .env open in the editor.
  • Mireth Harness (run /update). It tells MirethSpace when it is waiting on you, so panes show "needs you" every time. It leaves your .git folder and instruction files such as CLAUDE.md for you to edit. Git commands work as before, though a command that rewrites those files or changes git's hooks or aliases now always asks first, even with /proceed on. Plug-ins start more reliably: settings containing an & on Windows, commands written with ~, and very long tool names all work, and a plug-in that fails to start says why. Commands that run too long on Mac and Linux now stop on time. Claude Code's sign-in is no longer mistaken for an Anthropic key. Claude Sonnet 4.5 leaves the model menu ahead of its retirement.
  • On Mac, Glass is still not see-through. That is coming.

MirethSpace 0.3.6 · The Glass release · A window you can see through, every agent CLI one click away, and a hundred refinements underneath

September 15, 2026

  • Glass. A new look for MirethSpace in two tones, Glass Dark and Glass Light, sitting beside the Mireth template you already know. On Windows 11 the whole window turns to glass: your desktop and the windows behind it show through, softly blurred, and it stays that way when you click into another app. Terminals, the code editor, menus and dialogs all stay crisp and readable on top. Switching is instant and remembered, and the Mireth look is unchanged if you prefer it.
  • Launch harness. Every terminal's menu now lists the coding agents you can run: Mireth Harness, Claude Code, Codex, Gemini CLI, Grok Build, Hermes, Antigravity and more. Pick one and it starts in that pane, in that folder, with nothing to type. If something is already running there, you choose whether to take the pane over or open a new one beside it.
  • Your work is harder to lose. Closing a pane that is mid build, mid test run or mid ssh session now asks first. Launching an agent never takes over a terminal that is busy. The code editor notices when an agent has rewritten the file underneath you and asks before it saves over their work, so two of you can move fast in the same repo.
  • Agents keep their own lane. A message in Mail follows the agent it was meant for, even when a later agent picks up the same name. A task's instructions reach the agent as one clean message. Handing a pane to a different agent while you are switching tabs now lands where you meant it to.
  • Worktrees look after your branches. Removing a worktree whose branch still holds commits your main branch does not have now stops and tells you, and lets you keep the branch. A removal that does not succeed says so plainly. Project folders with an ampersand or other punctuation in the name work throughout.
  • The Agents page keeps up. A run that finishes while your other terminals are busy shows its results right away, and Stop reaches the run it belongs to.
  • Around a hundred smaller refinements across terminals, worktrees, Mail, Prompts, Settings, routines and updates, each one pinned by a test so it stays fixed.
  • On Mac, Glass Dark and Glass Light are available and the app is fully up to date, though the window is not see-through there yet. That is coming.

MirethVoice 0.1.4 · Dictation that says what you said, and settings that stick

September 15, 2026

  • Dictating over a silent moment types nothing at all, instead of slipping the transcriber's own placeholder into your document.
  • "Max duration" in Settings now stops the recording exactly when you told it to.
  • Change your hotkey or recording mode and the floating widget picks it up straight away, no restart.
  • Your clipboard is left as you had it. Dictating while an image or a file was copied no longer clears it, and your dictated words never linger there afterwards.
  • A dictionary replacement containing a dollar sign is inserted exactly as you typed it.
  • Turning the floating widget off closes it immediately, turning it on brings it back, and it sizes itself properly for whatever it is showing.
  • A long dictation history no longer gets in the way of your settings being saved, and MirethVoice tells you if saving ever fails.
  • Downloading the same voice model twice at once can no longer leave you with a broken file, and an interrupted download is discarded rather than kept.
  • The X button closes MirethVoice, as you would expect.

MirethSpace 0.3.5 · Restore a session, plus twenty-five fixes: links and the code editor work, and the window never freezes on git

September 12, 2026

  • Restore a session. MirethSpace now opens to Home, and "or restore a session" under Open a folder lists your last 10 sessions. Tick the panes you want and they reopen in their folders, with their earlier output shown above a fresh terminal. Agents are not relaunched, so nothing runs until you start it.
  • Links in terminal output open in your browser when you click them. Before, clicking a link an agent printed did nothing.
  • The code editor opens reliably, including offline. It now loads from inside the app.
  • Ctrl+Shift+F finds text in a terminal pane: results as you type, Enter and Shift+Enter to step through matches, Escape to close. Plain Ctrl+F still reaches the shell.
  • A slow git push, fetch or worktree creation no longer freezes the window while it runs.
  • On Windows, closing MirethSpace also ends the background processes its terminals started, so nothing is left running after you quit.
  • The app starts even when its saved workspace is damaged. A corrupt entry in the saved tab list used to throw before the first screen and leave the app unstartable until its storage was cleared by hand; a bad entry is now skipped and the good tabs beside it still come back.
  • Shrinking the grid, going Home, or closing a pane that is in the middle of a build, a test run or an ssh session now asks first. Before, only panes running an agent were protected.
  • Terminal panes say "blocked" in red when a trust prompt or a chooser is waiting for an answer, and pressing Enter there picks the highlighted option.
  • A worktree whose folder you deleted outside the app now says "folder missing" and offers Restore, instead of listing as healthy and opening a blank terminal.
  • The Memory panel now sees the notes your agents write, labels where each note came from, and hides a note that has been superseded instead of drawing it as still true.
  • The Worktrees panel no longer shows the previous project's worktrees after a tab switch, and if Restart to update fails it says so instead of looking like a dead button.
  • Three narrow-window fixes for the right rail: the Fleet roster no longer buries + New, the memory graph's toolbar no longer paints over its backlinks, and Alexandr's Deep button no longer reads Dee.
  • The Command page no longer redraws itself every second during a live run.
  • Mireth Harness: --worktree isolation now covers shell commands, not just file edits, so a run started there cannot reach outside its own worktree. Run /update to get it.

MirethSpace 0.3.4 · The Astra release · GPT-6 Astra, and an Assistant that can take files and pictures

September 9, 2026

  • GPT-6 Astra is in the Assistant model picker, alongside Claude, Gemini and Alexandr, with a reasoning effort picker from low to max. Bring your own OpenAI key or use credits.
  • Attach files to an Assistant message: drop them on the composer or use the paperclip. Each file shows as a chip you can remove, and a file that cannot be read says why instead of vanishing.
  • Show the Assistant a picture. Drop a png, jpeg, gif or webp and a model that can see (Astra, GPT-4o, Claude) gets it. A model that cannot see says so on the chip and nothing is sent.
  • Every code block in a reply can be saved as a file or inserted into the open editor tab.
  • Terminal panes have Attach file in their menu: pick a file and its path lands at the prompt in the agent's own syntax, ready for you to press Enter.
  • The Mireth Harness can send pictures too: @image:path, or drop one into the terminal. Run /update to get it.
  • Opening a folder for the first time asks what should happen first and launches an agent already working on it. Starting in a folder you have not used before no longer closes the session: the app now waits for Claude Code's trust question to be answered before sending your opening request.

MirethVoice 0.1.3 · Silence stays silent

September 9, 2026

  • Pressing the dictation key without speaking used to type a placeholder into whatever you had open. It now types nothing at all, and real dictation is unchanged.
  • Push to talk no longer sticks on. Releasing the key always stops listening, even when a quick press and release arrive together.
  • Security hardening: your sign-in token is kept by the operating system rather than in the web view, the window runs under a content security policy, file access is limited to what the app needs, and links that open the app are checked before they are followed.

MirethSpace 0.3.3 and Mireth Harness · Prompts tuned for Claude Fable 5.1

September 7, 2026

  • MirethSpace 0.3.3 gives the Assistant room to answer on Claude Fable 5.1: the reply cap rises from 2048 to 16000 tokens, so thinking no longer starves the reply. Swarm role presets now explain how the mailbox works.
  • The Mireth Harness no longer sends a Claude model a half-finished message to continue from, which Claude rejects. When Claude declines a request under its content policy, the reason is shown instead of a bare refusal. Run /update to get it.
  • Harness prompts say their rules once, at normal volume: the compaction summary, the clarify tool, the delegate brief and the identity contract. Compaction no longer rewrites the system prompt, so the provider's cache stays warm.
  • MirethMCP tool descriptions now state what each tool returns and which fields an update replaces.

MirethSpace 0.3.2 and Mireth Harness · A correctness pass, and skills in the harness

September 4, 2026

  • MirethSpace 0.3.2 fixes the places work could go missing. Checkpoints no longer drop command blocks while an earlier one is still saving, a stale git lock no longer disables them for a project, and a stale worktree past its cutoff keeps a branch that still holds unpushed commits.
  • The board and agent list show only the active project, a delete that failed offline is retried, splitting a pane opens its terminal immediately, and Quick Open finds dotfiles.
  • The Mireth Harness now ships seven skills you run by name: /code-review, /commit, /debug, /explore, /perf, /refactor and /test. Run /update to get them.
  • Harness fixes: on Windows a deleted file can be undone with /rollback, Claude streams like every other provider, /resume brings the plan back and not just the conversation, a delegated child survives a rate limit instead of dying, and verify-on-stop is on by default when the project has a verify command.

MirethSpace 0.3.1 and Mireth Harness · Claude Fable 5.1 is in

September 1, 2026

  • Claude Fable 5.1 is now in the Assistant picker in MirethSpace and in the /model menu of the Mireth Harness, on Anthropic and OpenRouter. Update the app, or run /update in the harness, and it is there.
  • Every panel got a pass. Sending a task to a terminal tells you when there is no free pane instead of pretending it worked, removing a swarm agent asks first, a routine cannot take a name that is already in use, and a prompt that fails to save says so.
  • Memory graph fixes: it no longer shows a previous folder's notes after you switch, labels stop growing as you zoom, and the highlight follows a reload.
  • Smaller fixes: a double click on a file opens one editor tab, block timings never print odd durations, a cleared pane's checkpoints stay cleared, and an agent launched from a cmd.exe pane gets its full instructions.

MirethSpace 0.3.0 · Steadier under load

September 1, 2026

  • If you are on 0.2.9, update now. A window bug in that build stops the app from closing normally. This release fixes it.
  • Terminals report their real state. An idle terminal reads idle instead of sitting on a permanent working spinner, and a command you recall with the Up arrow keeps its output.
  • Agent panes speak up. When a CLI stops to ask permission, the pane shows it, the tab badges it, and closing that tab warns you first.
  • Your work survives a project switch. Tasks and agents keep unsaved edits, cards stay in the project you made them in, and a stray click outside a task no longer discards what you typed.
  • Sending a task to a terminal now saves the instructions you edited, and editing one agent no longer overwrites another.
  • Connections are steadier. A pasted API key is checked before the app calls itself connected, a rejected key cannot sign you out, signing in works even if you closed the app partway through, and a slow server can no longer leave the app waiting forever.
  • Smaller fixes: opening a file reveals the editor panel if you had collapsed it, closing a background editor tab no longer switches to it first, and merge review reports a failed read instead of showing an empty diff.

MirethSpace 0.2.7 to 0.2.9 · Terminal and worktree stability

August 2026

  • Terminals stopped wedging after heavy pane use. The cause was in the terminal plugin itself, so closing a pane now fully releases its console and slow terminal work no longer blocks the app.
  • Agent launches wait for the shell to actually be ready, and a terminal that fails to start now recovers on its own instead of sitting blank.
  • Isolated worktrees are safer to remove, and merge review no longer offers a destructive path without warning.
  • Assorted fixes: deleting a routine cleans up its script, memory note titles keep their punctuation, and the kanban board stopped reshuffling cards on every sync.

Mireth Harness 0.1.0 · The command line agent

August 17, 2026

  • Mireth Harness is a terminal coding agent: launch it in any terminal, point it at a model, and it reads, writes and runs code for you. Every risky command asks first.
  • Install it with one line from the download page. It needs Node.js 20.3 or newer and nothing else: no compiler, no native modules.
  • It runs on every model Mireth offers, Alexandr included, and switches between them with /model.
  • Type /update inside the CLI to pull the newest build and rebuild in place. /balance shows what is left on the provider you are using.
  • A waiting indicator now shows how long the model has been thinking, so a slow turn no longer looks like a hang.

MirethSpace 0.2.6 · Alexandr can search the web

July 28, 2026

  • Alexandr now searches the internet when a question needs current information, like prices, versions or news, and cites where the answer came from.
  • He also knows today's date. Both work in the Alexandr tab and in the right-rail Assistant when he is the selected model.
  • Answers that use tools arrive all at once rather than word by word, and the waiting notes now say what he is doing.

MirethSpace 0.2.5 · New home screen

July 27, 2026

  • Alexandr now has its own card on the home screen, right alongside Mireth's Forge and Forge Swarm.
  • Delete projects straight from the home screen.
  • The wordmark and hero text now use the same display font as the website, instead of the system default.
  • Fixed a rare visual flash when launching Alexandr, a stale reference left behind after deleting a project, and the command-blocks panel popping open unannounced.

Alexandr · The Mireth model goes live

July 23, 2026

  • Alexandr, the Mireth model, is live. Talk to him free on the Chat page with any Mireth account: zero credits, on every plan.
  • He is built for agentic development: planning, building, and reviewing, with the frontier models one click away in the same picker.
  • His first reply after a quiet spell can take up to a minute while he wakes. That is normal.

MirethSpace 0.2.4 · Signed on every platform

July 23, 2026

  • Keyboard reliability: preventive fixes for a rare state where all keyboard input stopped responding, plus diagnostics to catch any recurrence.
  • The Windows installer is now code-signed (Authenticode).
  • The macOS app is signed and notarized by Apple. It opens like any Mac app, no right-click workaround. One universal download for Intel and Apple Silicon.

MirethVoice 0.1.2 · Signed installer + macOS

July 23, 2026

  • The Windows installer is now code-signed (Authenticode). No functional changes.
  • MirethVoice for macOS (signed and notarized) is now on the download page.

MirethSpace 0.2.3 · Editor artwork

July 21, 2026

  • New editor empty-state artwork replaces the background image that showed phantom zoom buttons.

MirethVoice 0.1.1 · Widget polish

July 21, 2026

  • The floating widget window is now titled MirethVoice instead of a raw framework label.

MirethVoice 0.1.0 · MirethVoice launches

July 21, 2026

  • Voice dictation for your agents: local whisper transcription runs free on-device; Groq cloud transcription on the Pro plan.
  • Auto-update built in from day one.

MirethSpace 0.2.2 · Account info fix

July 21, 2026

  • Fixed Settings showing “Connected” without your email or credits after startup. Credits now load reliably from boot.
  • The app now recovers your sign-in automatically if the local token store returns a bad read.

MirethSpace 0.2.1 · First auto-update

July 21, 2026

  • Your account email now shows in desktop Settings.
  • First release delivered through the built-in auto-updater.

MirethSpace 0.2.0 · Launch

July 21, 2026

  • First public release: parallel AI agents building in real terminals, on your machine.
  • Downloads for Windows and macOS.
