Static binaries [binaries-2026-07-05_05-38]

Automated rolling build of static PRoot and utilities. Passed the native-binary contract/smoke gate (ADFA-4465).

v0.4.1-beta

K2Go v0.4.1-beta

Architecture-and-maintenance release after v0.4.0-beta: Share/rsync and install carved to clean architecture (more resilient on Android 12+), new operator feedback + a shared delivery backbone powering anonymous opt-in analytics, in-app language switching, and the finished Node 24 CI migration + branding refresh.

Highlights

• Share/rsync tab moved to clean architecture (pure domain + tests, survives
  recreation) with phantom-process resilience on Android 12+.
• Install flow rebuilt as observable progress in a foreground service that survives
  recreation.
• New operator Feedback (form + crash reports, email-first) and a shared offline
  delivery backbone that already powers operational, anonymous, opt-in usage
  analytics.
• App Language selector — switch the app UI language independently of the phone locale.
• Finished the Node 24 CI migration + refreshed K2Go branding in the README.

Delivery backbone, analytics & feedback transport (ADFA-4504, ADFA-4466, ADFA-4507)

• Shared offline store-and-forward delivery backbone (#106)

• Flip-ready Worker feedback transport behind a flag (mailto default) (#110)

Localization (ADFA-4304)

• In-app UI language selector (App Language) in Setup (#112)

CI & branding (ADFA-4472, ADFA-4444)

Docs

• Mark Phase 2 (concurrency) closed (#83)
• Refresh TECH_DEBT_PLAN — ADFA-4474 done (install survives recreation) (#91)
• Share export design overview with Mermaid diagrams (#101); remove SHARE_EXPORT_DESIGN.md (design/diagrams belong on Jira, not the repo) (#102)
• Refresh the tech-debt plan — Share tab (S14) carved + robustness (#111)

Full Changelog: v0.4.0-beta...v0.4.1-beta

Static binaries [binaries-2026-06-29_08-12]

Automated rolling build of static PRoot and utilities. Passed the native-binary contract/smoke gate (ADFA-4465).

v0.4.0-beta

K2Go v0.4.0-beta

First release under the Knowledge To Go (K2Go) name, on top of a large
security, reliability and build-integrity pass since v0.3.7-beta.

Highlights

• Rebrand to K2Go across the app: name, launcher icon, splash, dashboard, and README.
• Native binaries hardened: xz (and the bundle) now built fully static, with a contract/smoke gate that blocks publishing a broken rebuild.
• Security sweep: closed command/rsync/ADB injection paths, enforced TLS + download/rootfs integrity, and blocked tar path-traversal.
• Install & proot reliability: DNS on fast-install/restore, writable /dev/shm, failed-runrole detection, and resume/reentrancy fixes.
• Cleaner architecture: DeployFragment carved into focused controllers; off-main-thread polling.

Security & integrity

• Validate sync credentials — close rsync injection (#9)
• Allowlist module names — close command injection (#13)
• Validate ADB shell commands — close arbitrary-shell (#28);
• ADB key sign/verify-only + log-broadcast scope (#10);
• keystore caps restored (#21)
• Verify download integrity + fail-closed on TLS (#12)
• Block tar path-traversal on extraction (#15)
• Rootfs integrity verification iiab-tree-sha256-v1 + device-backup manifest (#37);
• validate rootfs + architecture on backup import/restore (#31)
• OTA updater security & correctness redesign (#30)

Install, proot & reliability

• Make iiab-android proot-safe — deterministic chroot/reboot handling (#22)
• Inject resolv.conf + hosts on fast-install and restore — no-DNS fix (#25)
• Bind writable /dev/shm for Ansible multiprocessing (#49) + detect failed runrole, stop false "installed" (#50)
• Clone installer repo into explicit iiab-android target dir (#63)
• proot process race / resume reentrancy / module selection across tabs (#64, #65, #66);
• safe process handle + reap on kill (#70)
• Drain process output to avoid deadlock / silent failures (#16); proot-safe dashboard copy cp -a (#29)

Networking / DNS

• DNS Clean-Architecture slice + single injection point (#26)
• Restore DNS Setup UI (#60)

Features & UX

• Live rootfs sizes + offline-gated projection (#6, #7);
• real device arch on the dashboard (#8)
• Backup import/restore UX — names, progress, spinner, extraction log (#34);
• transparency + spinner fixes (#40, #44)
• In-app OTA update progress dialog + cancel (#32)
• Portal WebView slice + two-finger map gestures (#35)

K2Go branding

• Launcher/monogram icon + custom splash with "powered by App Dev for All" (#41, #54, #55); footer → "Knowledge To Go" (#42)
• Rebrand user-facing strings + terminal banner (#53); K2Go Dashboard (#69)
• README rebrand + logo (#57) and full Spanish translation (#59);
• fork URLs + app display name (#33)

Native binaries & build (supply chain)

• Link xz fully static (-all-static at link) (#77); restore autoreconf -fi so tar/less build on the new image (#72)
• Native-binary contract/smoke + static-linkage gate (#74)
• Cache-first + token-fallback native artifact sync (#20); group rootfs tooling under tools/rootfs-builder/ (#78)

🛠️ Under the hood (architecture, theming, CI, docs)

Architecture / refactor: move extra-keys layout into app (#5); carve DeployFragment into:

• Planner (#48),
• Install (#51),
• Reset/Delete (#52),
• ADB/Share (#56),
• Backup (#43) controllers;
  off-main-thread dashboard status (#67); sync/adb thread-leak + volatile handle (#73); MainActivity shared executor (#75); rootfs projection via RootfsViewModel (#7).

Theming: semantic colour tokens + screen migrations

• Dashboard (#14),
• Usage (#17),
• Install/Deploy (#18),
• Share/Sync (#19);
• dark-theme storage-gauge fix (#39).

CI / tooling / lint / docs:

• phase-0 tech-debt guardrails + lint gate (#4, #11);
• skip APK sanity-check on docs/CI-only changes (#23);
• disable then re-enable the hanging fragment lint detector (#36, #58);
• MissingTranslation as a hard error + backfill (#61);
