Greptile Summary

This is the v0.64.11 release cut: it bumps the Xcode build number to 91 and marketing version to 0.64.11 across all targets, adds the release notes block to CHANGELOG.md, and registers the 0.64.11 feature-highlight entry in changelog-media.ts for the docs changelog page.

• cmux.xcodeproj/project.pbxproj: Eight build configurations all receive consistent CURRENT_PROJECT_VERSION (90→91) and MARKETING_VERSION (0.64.10→0.64.11) bumps; no discrepancies.
• CHANGELOG.md: New section documents workspace groups, focus/recently-closed history, agent hibernation, detachable SSH PTY daemon, font-size controls, and a large set of fixes and removals.
• web/app/[locale]/docs/changelog/changelog-media.ts: Adds the 0.64.11 feature-highlight block (title + 6 feature descriptions) as hardcoded English strings; the changelog page is served across all 20 locales but these strings are not routed through next-intl.

Confidence Score: 4/5

The version bump and changelog copy are correct and self-contained; the only gap is that the new feature-highlight descriptions are English-only on a multi-locale docs page.

All Xcode targets are bumped consistently and the changelog entries are accurate. The changelog-media.ts addition follows an established but untranslated pattern: the 0.64.11 feature highlight titles and descriptions are hardcoded English on a page served to 20 locales, introducing fresh non-localized copy alongside the pre-existing 0.64.10 gap.

web/app/[locale]/docs/changelog/changelog-media.ts — the new 0.64.11 feature descriptions need next-intl keys (or an acknowledged exception) before non-English changelog visitors get translated content.

Important Files Changed

Filename	Overview
CHANGELOG.md	Adds the v0.64.11 release notes section — straightforward changelog update, no issues.
cmux.xcodeproj/project.pbxproj	Bumps CURRENT_PROJECT_VERSION 90→91 and MARKETING_VERSION 0.64.10→0.64.11 across all 8 build configurations consistently.
web/app/[locale]/docs/changelog/changelog-media.ts	Adds the 0.64.11 feature-highlight entry; all title/description strings are hardcoded English and not routed through next-intl, so non-English visitors see English copy on the changelog page.

   Hardcoded English changelog copy served across all 20 locales

   The title and all six description strings in the "0.64.11" entry are hardcoded English and are not consumed from next-intl or any locale-specific source. page.tsx renders these strings directly on the changelog page, which is served under the [locale] route for every locale listed in web/i18n/routing.ts (ja, zh-CN, zh-TW, ko, de, es, fr, it, da, pl, ru, bs, ar, no, pt-BR, th, tr, km, uk). Non-English visitors see raw English feature descriptions. The same pattern exists in the "0.64.10" entry, so this is pre-existing debt, but the PR introduces fresh untranslated copy rather than fixing the existing gap.
