Releases: HarnessMD/munder-difflin
Release list
v0.5.5
Munder Difflin 0.5.5.
- A faster, steadier office. No freeze at launch, and a busy floor stays smooth.
- Stop and Archive keep your work. Archived agents stay archived, and Reopen brings them back.
- Dictation lands at your cursor, in the message box, a field or the agent's terminal.
- A second dictation model, whisper large-v3-turbo, one download away.
- Claude Sonnet 5.5 in the model picker.
- Agents manage Automations, and every agent reaches your integrations.
- Detach the IDE into its own window.
- A Halloween office, on by default, with a switch in Settings, General.
- Windows. Hooks run from a home folder with a space in its path or on a second drive.
Downloads: macOS .dmg (universal), Windows .exe (installer or portable), Linux .AppImage. SHA256SUMS.txt lets you verify what you downloaded.
This release carries the installers only, not the 0.5.5 source.
v0.5.3
Munder Difflin 0.5.3.
- Dictate into any app. Hold Option on the Mac and talk.
- Transcription on your machine. Whisper ships inside the app.
- Meetings hear both sides, You and Them.
- More than one office at a time. New Floor runs a second office in parallel.
- A missing CLI installs and signs in from the app.
- One Save in Settings, and your agents in your order.
Downloads: macOS .dmg (universal), Windows .exe (installer or portable), Linux .AppImage. SHA256SUMS.txt lets you verify what you downloaded.
This is a binaries-only release: the tag carries the installers, not the 0.5.3 source.
v0.5.2
Munder Difflin 0.5.2.
- Your name reaches your team. Agents' names travel sealed.
- "Not receiving" is said to the sender. On the relay.
- Who answers. One setting, Slack and teammates.
- Requests stop coming back. Startup waits for the restore.
- Michael, shorter. Terminals, memory, and the agents' composer.
Downloads: macOS .dmg (universal), Windows .exe (installer or portable), Linux .AppImage. SHA256SUMS.txt lets you verify what you downloaded.

v0.4.6
Munder Difflin v0.4.6
A local hive of Claude Code, Antigravity, Codex, Gemini, Cursor, Grok & Copilot agents that run themselves.
Messaging, routing, and remembering, coordinated by your clone, Michael, who you talk to. Local-first and open source.

What's new in 0.4.6
The release that speaks your language and updates itself. The interface now runs in Chinese and
Arabic, the auto-updater downloads and installs a new build end to end, fonts ship inside the app so
a blocked network never leaves you on a blank window, and the way agent engines are launched is
hardened. Plus the Settings rework, an IME fix for CJK typing, and 16 community pull requests.
- The interface speaks Chinese and Arabic. Pick zh-CN or Arabic in Settings — every string is
translated, with nothing falling back to English, and the terminals read right to left. Some
screens still need their padding and icons mirrored, and that is the next piece of work. - Updates install themselves. The badge advances check to available to downloading to downloaded
on its own, and the button at the end restarts into the new version. This is the release that
proves that path end to end. - Fonts ship inside the app. No Google Fonts fetch on launch, so the app opens at the same speed
on any network, including one where Google is blocked. The release drop's fonts are bundled too,
and it can no longer white-screen while a stylesheet loads. - Engine command launching is hardened. The name of the CLI an agent launches is validated
before it is ever resolved against your PATH, so nothing but a plain command name or an absolute
path reaches a shell. - IME typing no longer sends early. Pressing Enter to choose a Chinese or Japanese candidate
picks the word instead of firing the message with half-typed text. - Settings has one Save button. The Connections tab stops repeating itself; REST API, MCP,
Slack and webhooks each keep their place. - The app counts messages you send, not what they say. A single
message_sentevent closes the
activation funnel: a count and nothing else, no text, no length, no content of any kind.
TELEMETRY.mdlists it like every other event and the same opt-out applies. - The ASK ME card renders markdown. Questions with emphasis, bullets,
code, tables and links
now render instead of showing their raw asterisks.
A note on Pro
v0.5.0 launches with Pro and Teams plans alongside the community version. Community stays free, stays
open, and keeps getting updates. Pro ships with new features and integrations, with more posted
throughout the year, and it stays ahead of Community, for power users who want the full potential
of coding agents and agent harnesses. The Pro roadmap also includes a mobile app. The first 100 people on the
Founders' Wall get a month of Pro free, then 50% off the annual plan.

What's new in 0.4.5
The release that fixes the things you trusted and were quietly wrong. Cost reporting was off
by more than half after a restart, semantic memory never worked on Apple Silicon, and agents
could not talk to each other reliably. All three are fixed. Plus weekday scheduling, clickable
paths everywhere, one editor instead of two, and 23 community pull requests.
- Costs are reported right. The telemetry counter reset on every app restart while the
session id stayed the same, so the floor under reported spend by a wide margin. It is now folded
from the ledger, with a separate session figure kept alongside. - Semantic memory works on Apple Silicon. CoreML overflowed the quantized embedding graph,
every vector came back NaN, and chroma rejected every upsert. Embeddings are pinned to CPU
on macOS. - Agents talk to each other reliably. An inbox wake watchdog, no more stale nudges, mail to
a missing inbox is bounced and logged instead of dropped, a capped steer queue, atomic
webhook dispatch, and PROTOCOL.md refreshes on boot. - Workers are reliable to hire. Spawn, teardown, floor cards, and engine availability are
all checked before a hire is committed. - The renderer runs inside Chromium's sandbox.
- Windows agents quit when the app does.
- Restart to update no longer gets stuck when a running agent makes the app refuse to quit.
- Triggers run on weekdays at a time of day, not just on an interval, and they are DST safe.
- Focus mode survives a restart and you can edit an agent from inside it.
- Every path in terminal output is clickable. Markdown previews, source opens in the editor,
images and unknown types reveal in Finder or Explorer. - One editor. The fullscreen file overlay is gone, everything opens in the IDE, and the git
rail is collapsed by default. - Updating is one click. The title-bar badge downloads the build for your machine and tells
you how to install it, it sayslatestonce a check confirms you are current, and the first
run after an update opens that release's page. - Settings opens with a card carrying your version, your plan, and a way back to these notes.
- Terminals follow the window theme, Gemini CLI and Cursor Agent join the engine list, and
Michael hires on his own terms with editable agent names.

v0.4.4
Munder Difflin v0.4.4

routing, and remembering, coordinated by your clone, Michael, who you talk to. Local-first and open source.

What's new in 0.4.4
If you use Windows, this is the release that makes the app work. Agents could never
message each other there — they started, looked completely healthy, and quietly ignored one
another forever. That's fixed.
It's also the release that fixes the first five minutes. Setup could not be finished, and on a
brand-new install the parts that carry messages between agents never started until you quit and
reopened the app.
Windows
- Your agents can talk to each other. This never worked before. If you tried the app on
Windows and your team just sat there, that was this bug — not you. - Setup no longer runs off the edge of the screen.
The first five minutes
- Setup finishes. Accepting the suggested folder used to fail outright, and the folder box
was empty even though the text above promised a suggestion. Both fixed. - It tells you what's missing straight away, instead of walking you through four steps and
then sending you back to the first one. - A fresh install works immediately. Messages between agents, live status on the cards, and
"Restart & Continue" all used to stay dead until you restarted the app. Nothing said so.
New things
- Skills — see every skill your agents can use, browse 227 more, and install or remove them
in a click. - Prerequisites — one page in Settings that says which supporting tools you have, which you
don't, and what each one is for. A button asks Michael to set up whatever is missing. - Release notes you'll actually read — like this one. Updates can now bring a designed page
instead of a version number in the corner. - A card at the top of Settings with your version, plan, and a way to reopen these notes.
Dark mode
Rebuilt. Every button, box and input is drawn with a one-pixel border, and in dark mode
those borders were effectively invisible — so the whole app read as flat grey shapes. The
colours are re-tuned and checked for readability rather than picked by eye. Backgrounds are
softer, text is a warm off-white instead of glaring white, and the selected tab is legible again.
Everything else
Copy from a terminal comes back clean, with accents and dashes intact. Dictation pastes what you
just said. Images and screenshots open in the IDE. Michael sits first on the dock again and it's
obvious which agent you're looking at. Task cards stop going missing. Idle agents stop being told
to compact every hour. Grok 4.6 is selectable. The office stops drawing itself when nobody's
looking at it.
For the nerds — what actually happened, in detail
Windows: two separate bugs, one symptom.
The hive protocol reaches an agent as a command-line argument: multi-line, paren-heavy, ~6.1k
characters. A .cmd cannot be handed to CreateProcess, so any non-.exe target was spawned as
cmd.exe /d /s /c "<one pre-escaped string>". cmd.exe treats CR/LF as a statement separator
before quoting is considered, so the argument was truncated at its first newline — taking the
block that names inbox/ and outbox/ with it. Escaping cannot fix this: cmd.exe has no
backslash escape, every " toggles quote state, and no escape exists for a newline. The fix
decodes the npm shim to its interpreter and script and spawns that with an argv array, so
node-pty's MSDN/CRT escaping hands the whole prompt to CreateProcess (ceiling 32767, not 8191).
The first fix still missed OpenCode. opencode-ai's bin is ./bin/opencode.exe — a compiled
binary, not a JS script — so npm writes an interpreter-less shim ("%dp0%\..\opencode-ai\bin\opencode.exe" %*).
The resolver only modelled "interpreter + script" and returned null, falling straight back to the
truncating path for every Windows OpenCode install. Diagnosed on macOS by generating the exact
shim with npm's own cmd-shim package; the resolver now handles direct-executable shims, and the
previously silent fallback logs which target it could not decode.
First-run bootstrap. bootstrapHiveServices() runs once at app-ready and opens with
if (!hive.enabled()) return — and a fresh install has harnessHome: null at that moment.
Onboarding then sets it through config:update, which did not re-bootstrap. The message router
(hive.startRouter(), the poll loop draining outbox/ → inbox/), the hook server, the
telemetry collector and the mission scheduler all stayed dead for the entire session. changeHome
had always handled this by relaunching; onboarding does not relaunch. It now bootstraps on the
null → set transition. A second source also records the live session id, so "Restart & Continue"
has a resume key even when a hook never lands.
Onboarding. The folder field read window.process.env.HOME, which is always undefined
under contextIsolation: true with only cth bridged — so the "suggested" default could never
appear. It now suggests ~/HarnessAgents literally, which normalizeHiveHome/expandTilde
already expand at both the config-write boundary and ensureHarnessHome's mkdir. The overlay
also centres with margin: auto rather than align-items: center, because a centred flex item
that overflows is clipped at the top and unreachable by scrolling.
Dark mode. Text always measured fine (11–14:1). ink-300 measured 1.73–2.09:1 — and it is
the structural token, used 187 times, 93 of those as inset 0 0 0 1px. Below ~3:1 a one-pixel
line is not perceivable. It is now 3.4–4.0:1, the ground sits at luminance 0.009–0.020 rather than
near-black, and text is 0.71 rather than 0.84. The selected Command Center tab was painting
ink-900 (near-white in dark) on a light accent fill at 1.55–1.87:1; a new --cth-on-accent
token is dark in both themes and takes it to 7.0–8.5:1. The xterm palette re-states these values
because xterm takes literals, so it moved with them.
Release drops. A release body may carry an authored HTML page between `
<style> html, body { height: 100%; } body { overflow: hidden; } .stage { height: 100%; } .pg { position: absolute; opacity: 0; pointer-events: none; } .page { display: none; height: 100%; flex-direction: column; padding: clamp(24px, 4vw, 46px); } #pg1:checked ~ .stage .p1, #pg2:checked ~ .stage .p2, #pg3:checked ~ .stage .p3, #pg4:checked ~ .stage .p4, #pg5:checked ~ .stage .p5, #pg6:checked ~ .stage .p6 { display: flex; animation: rise .34s cubic-bezier(.2,.7,.3,1) both; } @Keyframes rise { from { opacity: 0; transform: translateY(10px); } to { opacity: 1; transform: none; } } .content { flex: 1; min-height: 0; overflow-y: auto; } .center { display: flex; flex-direction: column; justify-content: center; } .nav { flex-shrink: 0; display: flex; align-items: center; gap: 12px; padding-top: 16px; margin-top: 12px; border-top: 1px solid var(--line); } .dots { display: flex; gap: 7px; flex: 1; } .dot { width: 7px; height: 7px; border-radius: 999px; background: rgba(20,19,26,.16); cursor: pointer; transition: background .2s, transform .2s; } .dot:hover { background: rgba(20,19,26,.34); } .dot.on { background: var(--accent); transform: scale(1.25); } .btn { cursor: pointer; border-radius: 999px; font-size: 13.5px; font-weight: 600; padding: 9px 18px; border: 1px solid var(--line); color: var(--ink-soft); user-select: none; transition: background .16s, color .16s; } .btn:hover { background: rgba(20,19,26,.04); } .btn.primary { background: var(--ink); border-color: var(--ink); color: #FBFAF8; } .btn.primary:hover { background: #2a2733; } .kicker { font-size: 11.5px; font-weight: 700; letter-spacing: .14em; text-transform: uppercase; color: var(--accent); margin: 0 0 14px; } h1 { font-size: clamp(1.8rem, 4.4vw, 2.7rem); } .lede { margin-bottom: 1.4em; } .big { font-size: clamp(3.2rem, 10vw, 5.4rem); line-height: .92; letter-spacing: -.045em; font-weight: 700; margin: 0 0 .1em; background: linear-gradient(135deg, #14131A 20%, #1B7F5A 115%); -webkit-background-clip: text; background-clip: text; color: transparent; } .stat { display: flex; gap: 24px; flex-wrap: wrap; margin-top: 24px; padding-top: 18px; border-top: 1px solid var(--line); } .stat b { display: block; font-size: 1.5rem; letter-spacing: -.03em; font-weight: 680; } .stat span { font-size: 12px; color: var(--ink-soft); } .tag { display: inline-block; font-size: 10.5px; font-weight: 700; letter-spacing: .1em; text-transform: uppercase; color: var(--accent); background: rgba(27,127,90,.09); padding: 4px 9px; border-radius: 999px; } .quote { border-left: 2px solid var(--accent); padding-left: 15px; margin: 18px 0 0; color: var(--ink-soft); font-size: 14.5px; } .rows { list-style: none; padding: 0; margin: 0; } .rows li { display: grid; grid-template-columns: 96px 1fr; gap: 12px; align-items: baseline; padding: 7px 0; border-bottom: 1px solid var(--line); font-size: 13.5px; } .rows i { font-style: normal; font-size: 10px; font-weight: 700; letter-spacing: .09em; text-transform: uppercase; color: var(--ink-soft); } .rows b { font-weight: 620; } .rows p { margin: 1px 0 0; color: var(--ink-soft); font-size: 12.5px; } .card { border: 1px solid var(--line); border-radius: var(--radius); padding: 16px 18px; } .card h2 { margin: 10px 0 .2em; font-size: 1.15rem; } .card p { margin: 0; color: var(--ink-soft); font-size: 13.5px; } .split { display: grid; grid-template-columns: 1fr 1fr; gap: 16px; align-items: start; } /* 16:10,...Contributors

Important
If you are reading this on a -rc pre-release page, download from the Assets list at the
bottom of THIS page — not from the table further down. Those table links point at
releases/latest, and GitHub deliberately excludes pre-releases from that, so they would hand
you the previous stable build instead. The same exclusion is why installing an rc does not put
the rest of the world on it: the in-app updater reads the same endpoint.
This pre-release exists to verify Windows. Agent-to-agent messaging on Windows is fixed here,
but the fix was written and unit-tested on macOS and has never been executed on a Windows
machine. If you are testing it: spawn an npm-installed engine (OpenCode), ask the agent where its
inbox and outbox are, and have two agents message each other. Please report anything that
misbehaves on the issue tracker.
What's new in 0.4.4 — Windows agents can finally talk to each other
On Windows, agents were never told they could message each other. They started, rendered,
and looked perfectly healthy — but a multi-line prompt handed to a CLI through cmd.exe is cut
off at its first newline, and the part that got cut was the protocol block naming an agent's
inbox and outbox. So no agent ever wrote mail, and none ever arrived.
- Agent-to-agent messaging works on Windows. Prompt-carrying spawns now run the CLI's real
interpreter directly instead of routing throughcmd.exe, so the whole protocol survives.
Anything we can't decode falls back to exactly today's behaviour. - Setup can finish again. Accepting the suggested
~/HarnessAgentsfolder wrote a literal
~, and the wizard then died onENOENT: mkdir '~/HarnessAgents'with the interface pushed
off-screen — on the very first thing a new user does. - Copying from a terminal is clean. The Edit menu was intercepting ⌘C before the terminal
saw it, so copies came back with the wrong text and with—mangled into‚Äî. - Agent terminals are UTF-8. They ran with no locale at all, so tools inside them fell back
to a 1980s character set and miscounted any non-English text. - Screenshots are visible. Images open in the IDE instead of "binary file (not displayable)",
and agent-written markdown reports finally render the screenshots they embed. - The IDE says whose workspace you're in, and points out the search shortcuts (⌘F, F1) that
were already there. - This notice tells you what changed. Updates used to announce only a version number.
- Task cards no longer vanish when two things edit the board at once; idle agents stop being
asked to compact every hour; "Restart & Continue" works on an agent that already died; an
unusual message id no longer silences an agent's mail permanently; the office floor stops
rendering while you're in a fullscreen terminal; Grok 4.6 is selectable.
Note
Windows users: this is the release that makes multi-agent work on Windows at all. If you
tried it before and your agents sat there ignoring each other, that was this bug.
Still new in 0.4.3 — Michael is the logo
The mark is a face now. Munder Difflin has always been an office you watch people work in,
and the icon was a pair of script initials on a gradient. It's Michael — your clone — drawn in
the app's own pixel art, on the brand yellow, looking straight back at you.
- One mark, everywhere. The dock icon on macOS, Windows and Linux, the site favicon and
header, the in-app toolbar, and the README all render the same portrait. No variant is a
redrawing of another. - The SVG is the source of truth. The mark is authored as pure vector — every pixel of the
sprite is a rect, with no fonts, no gradients and no filters — and every raster inbuild/
anddocs/is generated from it bytools/make-logo.cjs.
The old icon depended on the Lobster webfont being installed to render correctly. - Icons are native at every size. A real multi-resolution
.icns(16→1024, with the macOS
drop shadow) and a.icocarrying six sizes, plus a 32px favicon and a 180px apple-touch-icon,
so nothing is a downscale of a 512px image any more. - Brighter call-to-action buttons. The download button took its fill from the same token as
accent text, which has to stay dark enough to read on a white page — so on the light theme
it came out brown. Fills now have their own token and start at what used to be the hover colour.
Note
Appearance only. No functional change in this release: the update carries the new icon into
your dock, and nothing else moves.
Still new in 0.4.2 — Anonymous usage stats, done in the open
Munder Difflin now sends a small set of anonymous usage events (app opened, agent spawned,
feature used) so we can tell whether features are actually used. It is built the way an
open-source project should build it:
- TELEMETRY.md is the
complete contract. Every event and property is listed there, and the code enforces that list
as a hard allowlist — anything not in the table cannot be sent. No prompts, no transcripts, no
file paths, no repo names, no identifiers. Events are PostHog anonymous events (no person
profile, no identity), keyed by a random UUID you can delete. - Opt-out, three ways. Uncheck it during onboarding, flip Settings → General → Anonymous
usage stats, or set the standardDO_NOT_TRACKenv var. - Forks send nothing. The analytics key is injected only in release CI — building from
source produces a build where the analytics module is a complete no-op.
Still new in 0.4.1 — The app says what the site says
Michael is your clone. The website has been describing Munder Difflin as a clone of you that
works around the clock — the app still called it a "GOD agent." Now they match.
- Your clone, not the GOD agent. Michael is described as your clone throughout onboarding,
and his card on the floor carries a BOSS tag — he's the boss of the agents, you're still
the boss of him. - Onboarding was rewritten. It opens on what you actually get ("a clone of you, working
24/7") instead of a feature list, and the engine card no longer advertises three engines when
ten ship — Claude Code, Codex, Grok, Kimi, Antigravity, Qwen, OpenCode, Crush, pi and Copilot
are all named.
Note
This release changes wording only. The god agent id, the hive folder layout, and message
routing are untouched, so existing hives, memory, and running agents carry over exactly as they
are. Nothing to migrate.
Note
Auto-update carries you here from v0.3.7 or later. If you are still on v0.3.5 or v0.3.6,
those builds shipped the broken updater and need one manual install — grab the download below,
once.
Previously
- 0.4.0 — the brand grew up: one yellow "MD" mark across the dock icon, in-app logo, site
favicon, and munderdiffl.in; the landing page rebuilt around real screenshots and a live
pixel-floor sim; pricing reframed around Private Cloud and Private Network. - 0.3.9 — Settings → General answers "am I up to date?" directly, and removes 0.3.8's
usage-limit guard that never released held agents. - 0.3.8 — memory condensation works for the first time; a Triggers hub; one compaction
schedule instead of two; a readable commit history. - 0.3.7 — auto-update actually runs: a CommonJS/ESM import bug meant the native updater never
fired in any packaged build since v0.3.4, and the failure was swallowed by acatch. - 0.3.6 — a machine with nothing on it can run agents: Node and npm install themselves
(verified against the officialSHASUMS256.txt), hooks stopped dying with exit 127,~/dev/foo
paths resolve, and the office floor rebuilds itself after losing its GPU context. - 0.3.5 — a send now escape hatch for a paused message queue, and a compact Command
Center header. - 0.3.4 — talk mode that knows the floor, markdown previews, the IDE git time-machine
(history + branch compare), redesigned Settings, xAI Grok and Kimi Code, and a single
delivery gate for every automatic writer. Community work by
@gts-47 and @qschmick. - 0.3.3 — the built-in Monaco IDE, and GitHub Copilot CLI as the first community-contributed
engine (@anxkhn). - 0.3.2 — Realtime Michael: a voice channel to the GOD orchestrator.
- 0.3.1 — three more engines: OpenCode, Crush, and pi.dev.
