# cmux Release Prefer the `/release` command. It determines the new version (minor by default), gathers commits since the last tag, updates `CHANGELOG.md`, runs `./scripts/bump-version.sh`, commits, runs `./scripts/release-pretag-guard.sh`, then tags and pushes. The docs changelog page at `web/app/[locale]/(landing)/docs/changelog/page.tsx` renders from `CHANGELOG.md`, so there is no separate docs changelog source to update. ## Version bumping ```bash ./scripts/bump-version.sh # minor (0.15.0 -> 0.16.0) ./scripts/bump-version.sh patch # 0.15.0 -> 0.15.1 ./scripts/bump-version.sh major # 0.15.0 -> 1.0.0 ./scripts/bump-version.sh 1.0.0 # explicit version ``` This updates `MARKETING_VERSION` and `CURRENT_PROJECT_VERSION`. The build number auto-increments and must increase for Sparkle auto-update to work. Bump the minor version unless explicitly asked otherwise. ## Tagging ```bash ./scripts/release-pretag-guard.sh git tag vX.Y.Z git push origin vX.Y.Z gh run watch --repo manaflow-ai/cmux ``` If the pretag guard fails, run `./scripts/bump-version.sh`, commit the build-number bump, then retry. ## Release artifacts and secrets - The release asset is `cmux-macos.dmg`, attached to the tag. The README download button points to `releases/latest/download/cmux-macos.dmg`. - Signing and notarization require the GitHub secrets `APPLE_CERTIFICATE_BASE64`, `APPLE_CERTIFICATE_PASSWORD`, `APPLE_SIGNING_IDENTITY`, `APPLE_ID`, `APPLE_APP_SPECIFIC_PASSWORD`, `APPLE_TEAM_ID`. ## Detailed reference - [references/release-checklist.md](references/release-checklist.md): changelog tone, failure triage, and asset-rename fallout.
cmux package architecture, refactor layering, dependency inversion, file organization, DocC documentation, package design discipline, testability, and Swift 6 concurrency rules. Use before adding or meaningfully rewriting Swift files, Swift packages, coordinators, services, repositories, or public package APIs.
Backend TypeScript and Cloud VM development rules for cmux. Use when editing web/app/api, web/services, backend scripts, Cloud VM lifecycle, provider integrations, Postgres, Stack Auth pricing gates, migrations, or provider image build scripts.
Stripe checkout, pricing, subscription, Pro plan, webhook, and entitlement runbook for cmux billing work. Use when editing or debugging billing, pricing, Stripe Checkout, subscription recording, Pro plan status, webhooks, entitlement metadata, or pricing dev/prod tooling.
End-user browser automation with cmux. Use when you need to open sites, interact with pages, wait for state changes, and extract data from cmux browser surfaces.
Route work to cmux Cloud machines (persistent cloud VMs) from the CLI — `cmux vm route`/`run`/`agent` pick a machine for you; `vm tree` / `surface ls` show the surface catalog (This Mac and every machine: terminals, VNC screens, browsers) and `vm open` / `surface open` put any of them in a pane; plus create, exec, push/pull, ports, checkpoints, forks. Use when an agent should run builds, tests, servers, desktop/browser tasks, or another agent on a cloud machine instead of the local Mac, or when the user says "cloud machine", "cloud VM", "run it in the cloud", or "cmux vm".
Drive real macOS apps from a cmux agent session via the bundled computer-use engine (accessibility tree + screenshot perception, click/type/scroll/drag, branded agent cursor). Use when an agent should see and operate GUI apps on the local Mac, when computer-use tools are missing or failing, or when explaining how to grant permissions, brand the cursor, or focus the driving session.
Build a custom cmux sidebar from a plain-language request. Use when the user asks for a custom sidebar, a sidebar that shows their workspaces/tabs/PRs/clock, a vibe-coded sidebar, or anything involving files in ~/.config/cmux/sidebars/. Covers authoring the interpreted SwiftUI-style file, enabling the beta flag, selecting it, and iterating with hot reload.
