Summary

Adds a curated ## Unreleased section to CHANGELOG.md for the next classic release: 5 Added, 3 Changed and 38 Fixed lines covering v0.65.2..2e75a0089b4.

Why a CHANGELOG edit and not PR bodies: /release builds entries from each PR's ## Changelog line, but 83 of the 135 PRs in that range had no line or a broken one. Rewriting 60 merged PR bodies, many of them teammates' public PRs, was refused. /release already folds leftover ## Unreleased entries into the new version section (cmux-release skill), so this is the supported way to hand it curated lines.

Notes for whoever runs /release:

• Dedupe: these entries already cover their PRs. Drop any line /release generates for a PR linked here.
• Range: PRs merged to main after 2e75a0089b4 still come from their own Changelog lines.
• Left out: CI, staging dogfood, merge tooling and iOS-only changes (Fix iOS terminal sizing priority across background resume #18641, Fix iOS cmux-tui topology reconnect (#21001) #21129, fix(ios): keep stale SSH attaches from reclaiming surfaces #18539, iOS billing: Monthly/Yearly plans, refund request, analytics, unavailable-plans retry, no web purchase links #20572).
• Docs page: the docs changelog page only parses ## [version] - date headings and skips text before the first one, so this section doesn't render until the release folds it in.

The source is the classic patch-notes draft on cmuxterm-hq#2513, rewritten into the Added/Changed/Fixed format.

Changelog

none

Testing

Docs-only. I read web/app/lib/changelog.ts's parseChangelog: it ignores lines before the first version heading, so the docs page is unchanged.

Summary by cubic

Adds a curated ## Unreleased section to CHANGELOG.md for the next classic release, covering v0.65.2..2e75a0089b4 with 6 Added, 3 Changed, and 38 Fixed entries.

This works around a gap in /release: it builds changelog entries from each PR's Changelog line, but 83 of the 135 PRs in range had none or a broken one, and rewriting teammates' PR bodies was refused. /release folds leftover ## Unreleased entries into the new version section, so this is the supported way to hand it curated lines.

Rollout notes

• Dedupe: these entries already cover their PRs, so drop any line /release generates for a linked PR.
• PRs merged to main after 2e75a0089b4 still come from their own Changelog lines.
• CI, staging dogfood, merge tooling, iOS-only, and staff-only changes were intentionally left out.
• Docs-only change; the changelog page doesn't render this section until the release folds it in.

English notes reach localized search

The new English entries appear in localized docs search even though the changelog page skips Unreleased. changelogSearchText() reads the entire file and adds the same text to every locale’s search index. Search results then display matching English excerpts to non-English users.

This violates the requirement to fully localize new user-facing changelog copy. Exclude Unreleased from search until publication, or provide translated search content for every supported locale.

Rule Used: Flag production user-facing text that is not fully internationalized across every locale supported by the affected surface: Swift UI/menu/alert/tooltip/error/command text must use String(localized:defaultValue:) or an equivalent localized API with a ... (source)

Full details: Description check

Explanation

The description provides a detailed summary and explains the release workflow and testing scope. It omits the Proof and Checklist sections, and the Changelog section says "none" even though this PR changes release notes, but the description is otherwise sufficiently complete.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Full details: Cmux Cloud Persistent Session And Early Input

Explanation

PASS. The reviewed range changes only CHANGELOG.md (+54 lines). It does not change Cloud terminal creation, transport, PTY readiness, input routing, authentication, idempotency, revision, or lease behavior. The Cloud-related text is documentation only, so the stated failure conditions are not introduced.

Full details: Cmux Swift Blocking Runtime

Explanation

PASS: The reviewed diff changes only CHANGELOG.md (+54 lines). It introduces no production Swift changes and no semaphores, waits, sleeps, delayed dispatch, polling, main-queue synchronization, or manual locks.

Full details: Cmux Browser Automation Off-Main

Explanation

PASS: The reviewed range changes only CHANGELOG.md (+54 lines). It introduces no browser.* socket command, routing change, WebKit/AppKit access, browser state mutation, or policy-test gap. The off-main browser automation rule is therefore not applicable, and existing debt is not worsened.

Full details: Cmux Expensive Synchronous Load

Explanation

The reviewed range changes only CHANGELOG.md (+54 lines). It adds no Swift code, agent-history loads, or interactive-path behavior. The custom failure condition for production Swift changes does not apply.

Full details: Cmux Cache Substitution Correctness

Explanation

The pull request changes only CHANGELOG.md (+54 lines). It introduces no production Swift, TypeScript, or JavaScript code and no persistence, history, undo, or snapshot implementation changes. The cache-substitution condition does not apply.

Full details: Cmux No Hacky Sleeps

Explanation

PASS: The pull request changes only CHANGELOG.md. The diff adds Markdown release notes and introduces no TypeScript, JavaScript, shell, or build/runtime code. It therefore introduces no fixed sleep, timer, polling loop, or wall-clock wait covered by the rule.

Full details: Cmux Algorithmic Complexity

Explanation

The pull request changes only CHANGELOG.md, adding 54 lines of Markdown. It does not change Swift, TypeScript, JavaScript, shell, runtime code, or collection-processing logic. Therefore, it introduces no algorithmic-complexity violation.

Full details: Cmux Swiftpm Lockfiles

Explanation

PASS: The pull request changes only CHANGELOG.md. It does not change SwiftPM packages, Package.resolved files, Xcode project package references, .gitignore, workflows, or dependencies. Therefore no SwiftPM lockfile rule applies.

Full details: Cmux User-Facing Error Privacy

Explanation

PASS. The PR changes only CHANGELOG.md. Its only error-related entry says “Cloud errors say what failed and what to try next,” using the allowed generic term “Cloud” and exposing no provider, raw error, credential, token, id, or payload. The other matching text is release-note feature or fix summaries, not user-facing error or recovery copy. The docs parser also skips the new ## Unreleased section until a version heading exists.

Full details: Cmux Source Artifacts

Explanation

PASS: The pull request changes only CHANGELOG.md. The diff adds a hand-written ## Unreleased documentation section with curated release notes. It does not add logs, screenshots, recordings, caches, build output, temporary directories, dependency checkouts, or other source-control artifacts.

Full details: Cmux No Test Or Debug Seam In Production Source

Explanation

The reviewed range changes only CHANGELOG.md (+54 lines). It contains no Swift files, no production Sources/ paths, and no test/debug seam or visibility change. The custom check is therefore not applicable.

Full details: Cmux Full Internationalization

Explanation

The PR adds user-facing changelog copy directly to root CHANGELOG.md; this is the only changed file. The rule requires changelog copy to come from a locale-specific source and to be represented for every locale. The web changelog reads raw CHANGELOG.md through web/app/lib/changelog-store.ts and renders it for all localized routes, while web/i18n/routing.ts lists 20 locales and no web/messages/ file changed. This confirms the standing failure remains.

Resolution

Move the new changelog entries into the locale-specific message/source system used by the changelog, update matching entries for all 20 locales in web/i18n/routing.ts, and make the changelog renderer consume those localized entries. Do not leave the new user-facing copy only in root CHANGELOG.md.

Orphaned: no activity for 14 h, and no lane holds a lease on it. Adopted by the orphan sweep: merged main in at e8eeac6. A later pass queues it for the merge hub if it is reviewed, small and red only on base reds.

Not re-run automatically: macos / macOS compile admission is not a machine failure.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

CI fast guards failed on b8783213a9 (https://github.com/manaflow-ai/cmux/actions/runs/39574159315). It does not block the merge; a red guard merged into main breaks it for every open PR.
The log named no failed step; see the run.

Agents: python3 scripts/ci/guard_attribution.py fix applies the mechanical fixes locally.

Review (independent subagent): BLOCK at e8eeac6

Placement, range and style are fine. Two entries are wrong and need fixing before merge. Both are one-line edits.

Blocking

1. A finished background subagent stops showing as running (#20346) says the opposite of what the PR fixed. Before Keep Claude background subagents running after parent stop #20346, a Claude parent Stop marked every child as ended (AgentChatSessionRegistry+ChildRuns.swift), so a background subagent that was still running showed as finished as soon as the parent turn ended. After the fix, Claude children stay running until their own SubagentStop. Suggested line: A Claude background subagent keeps showing as running after the parent turn ends, until it finishes ([#20346](https://github.com/manaflow-ai/cmux/pull/20346))
2. A verified cmux company email puts you on the Team plan with no machine limit (#21276) only applies to staff. companyPlan.ts gates it on isAdminUser, which means a verified cmux.com, manaflow.ai or manaflow.com email ("cmux staff accounts are on the Team plan by default"). No user outside the company can get it, so it should not be in the public changelog. Suggested fix: drop the line.

What I checked

• Placement: .claude/commands/release.md step 3 and skills/cmux-release/SKILL.md ("Changelog source") both fold leftover ## Unreleased entries into the new version, drop duplicates and remove the heading. parseChangelog in web/app/lib/changelog.ts skips everything before the first ## [x] - date line. Nothing else reads CHANGELOG.md structurally: sync-changelog.ts only copies it, vercel-ignore-build.sh and the CI area detectors only look at the path, and build-sign-upload.sh only says "See CHANGELOG.md". There is no appcast or release-notes generator that reads it.
• Range: all 55 linked PR numbers are squash commits in v0.65.2..2e75a0089b4 on main. None of them is already in the 0.65.2 or earlier sections.
• Not stale: there is no v0.65.3+ tag on origin, and the top of the CHANGELOG on main is still ## [0.65.2] - 2026-10-14.
• Spot-checked the diff or body of Add workspaceColors.unselectedFillOpacity for solid-fill workspace rows #21377, feat: opt in to trusted SSH OSC 52 clipboard writes #18442, fix(cloud): resume and bound cmux-tui client downloads #16305, docs: sync CLI references with current commands #20817, ci: ship the app stapled inside the DMG (main, needs Lawrence) #21217, Keep restored Claude resume bindings past previous-generation SessionEnd hooks #21368, Keep Claude background subagents running after parent stop #20346, fix(search): isolate global index per app bundle #16195, Add Review Approval for stored resume proposals #21367, web: company email accounts are Team with no Cloud machine cap #21276, fix(cloud): pause machines that wake while paused #21638, Fix Cloud VM computer-use MCP setup #20818, Keep a Cloud terminal's cwd: parse kitty-shell-cwd and publish early reports #20570, fix(worktree-seed): follow chained symlinks in the repository boundary check #21627, Fix Claude Teams pane width and stale split recovery #20830, Fix custom right-sidebar groups context #20354, Fix Codex memory worker session ownership #20849, Let Cmd+Shift+/ open Help menu search (#21230) #21362 and Custom sidebar: expose workspace emoji in data context #20828. Apart from the two above, each line matches its PR. All of these PRs are on base main (classic), not feat-cmux-next.
• Credits: every author in the range is core team (Austin, Lawrence, Leo), so there are correctly no author callouts. I checked four reporter credits against their issues and all four are right: Setting for the opacity of workspace rows that are not selected (solidFill) #21232 @mmartinovich, Opt-in: let a trusted SSH machine write the Mac clipboard (OSC 52) in cmux-tui mirror panes #18324 @simjak, Late SessionEnd hooks from the previous generation's claude processes clear resumeBinding on restored panels (Claude tabs restore as plain shells after a double quit) #21226 @bowernite, Global search index (search.db) is shared across all cmux instances; each startup deleteAll() wipes other instances' documents #7440 @azooz2003-bit. The format (-- thanks @x for the report!, two hyphens, [#N](https://github.com/manaflow-ai/cmux/pull/N) links) matches 0.65.2.

Non-blocking

• The CLI reference matches this build (#20817): the PR only touched docs/ and agent skill references, not the app. It is fine to keep, but it is borderline as a user-facing change.
• A slow terminal download resumes instead of starting over (#16305): this is the Cloud cmux-tui client download. "The Cloud terminal client download resumes instead of starting over" would be clearer.
• The app inside the DMG is notarized on its own (#21217): "stapled" or "carries its own notarization ticket" is more accurate, since the app was already notarized.
• web/tools/build-docs-search.mjs indexes every CHANGELOG line, so these entries will show up in nightly docs search before the release. This is expected and harmless.

[teamleaderleo]

Review (independent subagent): SHIP at b878321

I re-checked the diff from e8eeac6 to b878321. Both blocking problems are fixed: the staff-only #21276 line is gone, and the #20346 line now matches what the PR did (Claude background subagents stay running until their own SubagentStop). The #16305 and #21217 wording is clearer and correct. The PR still only changes CHANGELOG.md, and all the checks from my earlier review still hold.
