Cuts v0.64.23 from 1,254 merged PRs and 95 direct commits since v0.64.22 (Aug 3 -> Sep 14).

Bumps MARKETING_VERSION to 0.64.23 and CURRENT_PROJECT_VERSION to 103, adds the CHANGELOG.md entry, and adds the 0.64.23 changelog-media.ts highlights.

Added: Vault session search, checkpoints, and fork; inline replies to agent notifications on Mac and iPhone; full localization in German, French, Spanish, Arabic, Korean, and Simplified and Traditional Chinese; first-class Amp, Hermes, and Antigravity; Nushell; the Automations rule engine, agent-event hook context, and per-agent notification sounds; Notifications as a pane tab; Keep Mac Awake; pane resize shortcuts; group-scoped workspace cycling; right-sidebar tab customization; browser URL allowlist, download history, default zoom, and chromeless Dock browsers; MDM managed policies; File Preview syntax colors; Cmd+F in the Markdown and diff viewers; macOS privacy prompts for terminal child processes; CLI --command, read-selection, --json tree, comments list, guide; ssh-tmux remote notifications and Agent Teams over SSH; cmux TUI detached session owner, sidebar profiles, and CLI verbs. iOS (beta) gains per-Computer connection methods, Task Composer drafts and attachments, workspace sorting and groups, grouped notifications, and Markdown parity.

Changed: iOS transport rebuilt on Iroh (current iOS builds require cmux 0.64.23 on the Mac), Simulator streaming as a video lane, quiet reconnects, Tailscale Pairing window, journal-derived sidebar agent status, Ghostty colors no longer flip with app appearance, hidden-window terminals release Metal swap chains, Ctrl+D quit confirmation, macOS scroll bar setting honored, Sparkle 2.9.5, higher file-descriptor limit.

Fixed: workspace-switch ghosting and latency, main-thread hangs, idle CPU burn, crashes and beachballs on Intel and macOS 15/26/27, tab drags, Mission Control wedges, focus handoff, Dock panes, terminal input and selection, sidebar rows, window restore, Google Sheets CPU loop, browser crashes, persistent SSH reconnect and daemon bootstrap, agent hook timeouts, Claude/Codex/Pi/Kimi/OpenCode fixes, autoresume and hibernation, updater, CLI sockets, plus iOS (beta) typing latency, row corruption, push reliability, and reconnect fixes.

Cloud is mentioned once, as beta, launching in the next major release: cloud-machines-enabled-release is at 0% rollout and the Settings > Beta Features opt-in defaults off in Release, so no stable user can reach it.

Held out of the notes (not stable per the readiness pass): Computer Use (on by default but with a September fix storm and open onboarding issues), cmux sudo (landed via a direct commit while its PR is open), custom sidebars (self-labeled beta with open issues), local tmux persistence (opt-in vertical slice), CodeRouter CLI verbs (hosted service is private beta), SDK placeholders, Agent Chat UI, workspace todo controls, Pro upgrade UI, the sidebar Tailscale Pairing button, the mobile diff viewer (all flagged off in Release), terminal live-resize glue (fix reverted), terminal link routing (#12343, linked issues still open), and iOS keyboard dock rebuild, pixel scrolling, Tailscale pairing fixes, iPad split view, iOS 17/18 support, and iOS localization (open issues or same-day follow-ups). Reverted pairs (#12210/#12329, #11530/#11887, #10197/#11966, #8580/#10018, #10549/#10584) are excluded.

Localization

Supported macOS locales: en, de, fr, ar, es, zh-Hant, zh-Hans, ko, ja. The macOS catalogs were already complete on main; this PR completes the iOS catalogs for keys added in the release range.

  • ios/cmux/Resources/Localizable.xcstrings: 24 keys (demo computer name, notification history, screenshot reply strings, Keep Mac Awake caption, Mac update and version-gate copy) gained de/fr/ar/es/zh-Hant/zh-Hans/ko. Four top-level keys (computers.listauth.unverified.*, computers.version.outdated.*) were present twice since Prevent staging origins in production iOS builds #11524; the duplicate blocks are removed. Now 1440/1440 keys in all nine locales.
  • Packages/iOS/CmuxMobileShellUI/.../Localizable.xcstrings: 5 keys (Task Composer Liquid Glass setting and caption, diagnostics export/clear) gained ja plus the other seven locales. Now 217/217 keys in all nine locales.
  • Placeholders (%@, %1$@, %2$@, %lld) verified equal between English and every translation.
  • web/messages/ja.json is missing 81 keys, all added between March and July 2026 (blog posts, docs.base.*, docs.ohMyOpenCode.*, wall of love); out of this release's range, left as is.

Check output:

$ python3 scripts/localization_catalog.py check
6 catalogs, 9 locales: 0 parity errors
$ python3 scripts/lint-xcstrings.py
XCStrings lint passed: 19 catalog(s)
$ bash scripts/check-pbxproj.sh

$ cd web && bun test tests/changelog-pages.test.tsx tests/sync-changelog.test.ts tests/png-dimensions.test.ts
10 pass, 0 fail, 548 expect() calls

Summary by cubic

Cuts release v0.64.23, bumping MARKETING_VERSION to 0.64.23 and CURRENT_PROJECT_VERSION to 103, adding the CHANGELOG.md entry, and adding the 0.64.23 changelog-media.ts highlights.

Completes iOS localization: 24 keys in ios/cmux/Resources/Localizable.xcstrings and 5 in the CmuxMobileShellUI catalog now cover all nine locales, four duplicated top-level keys are removed, and the Chinese Task Composer caption now matches the English "transparent bar" wording.

Migration

  • iOS builds require cmux 0.64.23 on the Mac; the iOS transport was rebuilt on Iroh.
  • Cloud stays behind a 0% rollout beta flag, so no stable user can reach it.

Written for commit 6eae949. Summary will update on new commits.

Explanation

The PR adds new user-facing web changelog copy without locale-specific sourcing. web/app/[locale]/(landing)/docs/changelog/changelog-media.ts:29-61 hard-codes the 0.64.23 title plus six feature titles and descriptions in English. The changelog pages pass this object for every locale, and changelog-release.tsx:298-303 renders the values directly. No web/messages/*.json file contains corresponding 0.64.23 entries, while web/i18n/routing.ts lists 20 supported locales. The new English release section in CHANGELOG.md is also read directly by changelog-store.ts and rendered by the localized changelog pages. The two changed iOS catalogs otherwise have complete non-empty entries for all nine locales already supported by each catalog.

Resolution

Move the new changelog media title, feature titles, and descriptions into locale-specific message entries, and load them through next-intl (or an equivalent locale source) for all 20 locales in web/i18n/routing.ts. Provide matching entries in every web/messages/*.json file. Localize the new 0.64.23 CHANGELOG.md content as well, or change the changelog data path so each locale receives localized release sections and metadata instead of the single English source.

The English source says "a transparent bar"; the zh-Hant and zh-Hans
values said toolbar, which the iOS UI does not use there.
