Codex Lifeboat v3.4.2

Codex Lifeboat 3.4.2 — clearer interface and path details

Nederlands

Codex Lifeboat 3.4.2 keeps the same simple goal: carry Codex projects, chats,
settings, and related local data safely between Windows 10/11 computers.

What changed

• A redesigned professional dashboard makes backup, restore, verification,
  recovery points, and diagnostics easier to find.
• Backup results now show clearer status, project, conversation, and size cards.
• Path-portability notices explain which local references are translated,
  preserved, excluded as machine state, or need review.
• Unknown path references remain included and do not block a valid backup or
  restore; only an old link may still require attention after moving computers.
• Local full paths stay private and are removed from saved or copied reports.
• The sidebar title now remains fully visible with Windows display scaling.

Download

Download Codex-Lifeboat-Windows-x64-Portable.zip, extract it completely, and
start Codex-Lifeboat.exe. Do not run the application inside the ZIP file.

This remains a public testing release. Keep an independent copy of irreplaceable
data and report unexpected results through GitHub Issues.

Codex Lifeboat 3.4.1

Codex Lifeboat 3.4.1 — faster backup and safer hand-offs

Nederlands

Codex Lifeboat 3.4.1 is a public testing release for carrying local Codex
projects, conversations, skills, and portable settings between Windows 10/11
computers. It is an independent community project, not an official OpenAI product.

Download

Most users should download only:

Codex-Lifeboat-Windows-x64-Portable.zip

Extract the ZIP completely and run Codex-Lifeboat.exe. Python, installation,
and administrator rights are not required. The standalone EXE and SHA256.txt
are also attached.

What changed

• Faster backup creation: payload files are hashed once during creation instead
  of being read immediately for a duplicate full verification pass.
• Verify backup remains the explicit independent SHA-256 reread of every file.
• Large conversation histories with hundreds of unavailable historical attachment
  paths are analyzed without the previous severe slowdown.
• The project-selection window opens maximized, shows more rows, and can be
  restored normally from the Windows taskbar.
• Added a read-only diagnostics center with an anonymized support report.
• Added a schema-aware portability audit for path-bearing Codex data.
• Added read-only Git explanations for project conflicts without changing Git.
• Critical JSON and checksum metadata now use durable atomic replacement.
• Safe conversation continuation is automatic only when the destination history
  is proven to be an exact unchanged prefix of the longer backup conversation.

Safety and validation

• Authentication and machine identity are never transferred.
• Every completed package passes structural, SQLite, manifest, path, size, and
  lineage checks before receiving its final name.
• Verify backup independently rereads and checks every payload SHA-256.
• Source, packaged EXE, and freshly extracted ZIP pass 75/75 checks and 12/12
  automated Windows compatibility scenarios.
• Backups are not encrypted and may contain source code, Git history, .env
  files, API keys, and conversation content. Keep backup media secure.
• The EXE is not commercially code-signed, so Windows SmartScreen may warn.

Public testing status

This remains a pre-release while physical Windows 10, second-computer, USB-removal,
and complete A-to-B-to-A evidence is collected. Keep an independent copy of
irreplaceable data and never attach a real backup to a public issue.

Codex Lifeboat v3.4.0

Codex Lifeboat 3.4.0 — public testing release

Nederlands

Codex Lifeboat 3.4.0 is a major beta/release-candidate update for carrying local
Codex projects, conversations, skills, and portable settings between Windows
10/11 computers. It is an independent community project, not an official OpenAI
product.

Download

Most users should download only:

Codex-Lifeboat-Windows-x64-Portable.zip

Extract the ZIP completely and run Codex-Lifeboat.exe. Python, installation,
and administrator rights are not required. Codex-Lifeboat.exe is also attached
separately for advanced users. Verify the files using SHA256.txt.

Highlights

• Complete, independently verified backups of selected project directories.
• Recent, archived, pinned, project-linked, and projectless local conversations.
• Portable skills, settings, available attachments, and consistent SQLite snapshots.
• Pre-backup project inventory with paths, file counts, sizes, largest folders,
  and optional whole-project exclusion.
• Username-independent Windows paths plus reviewed external-drive, USB, and UNC mapping.
• Permanent project identities and backup lineage for A-to-B-to-A hand-offs.
• Read-only restore comparison showing conflicts, actions, and required disk space.
• Explicit per-chat and per-project conflict decisions; data is never silently merged.
• Transactional, SHA-256-verified project replacement with rollback after failure.
• Destination-only data retained by default, with reviewed archive or recoverable removal.
• Managed local recovery points that keep the two newest valid points by default.
• Clear measured/animated progress through hashing, analysis, preflight, and final checks.
• Complete English interface and documentation with Dutch translation.

Safety and validation

• Source authentication and machine identity are never transferred.
• The destination login and machine identity are preserved.
• Every completed package passes independent validation before it receives its final name.
• Source, packaged executable, and freshly extracted ZIP each pass 66/66 checks and
  12/12 automated Windows compatibility scenarios.
• The EXE is not commercially code-signed, so Windows SmartScreen may warn.
• GitHub Actions publishes build-provenance attestations for all three release assets.
• Backups are not encrypted and can contain source code, Git history, .env files,
  API keys, and conversation content. Keep backup media secure.

Public testing status

This release is intentionally marked as a pre-release while real-world evidence
is collected for Windows 10, a second Windows 11 computer, physical USB removal,
and complete PC-A-to-PC-B-to-PC-A hand-offs. Keep an independent copy of
irreplaceable data.

Read the testing guide
and report results with the Compatibility test result issue form. Never attach
a real backup or unsanitized logs.

Compatibility

• Application: Windows 10/11 x64.
• Package reader: formats 2.0 through 2.4.
• New backups: format 2.4.
• Upgrade: replace the previous extracted application files with this release;
  existing backup packages do not need to be modified.
