CPPO 1.18.2

Install: from the VS Code Marketplace, or download cppo-1.18.2.vsix below → Extensions → ⋯ → Install from VSIX… → reload. Linux, WSL, Remote-SSH and dev containers only.

Recommended update — it protects a host's saved state from stale uninstall scripts of earlier copies (see the first item below). If you ever uninstalled an older copy (warrenb213.cppo, beboutit503.cppo, Claude Parallel Accounts) from the Extensions view and haven't restarted the VS Code server since, that copy's script is still pending: update first, and see Moving from an earlier copy in the README.

CPPO is a personal project — keep personal and work accounts, keys and code on separate machines, and follow each provider's terms (see Terms of service in the README).

1.18.2 — 2026-10-22

Fixed

• A stale uninstall script wiped a host's saved state. VS Code runs an uninstalled extension's script at the next server start, not at Uninstall. On one host, three copies uninstalled days earlier (DercasDrol.claude-parallel-accounts 1.15.3, warrenb213.cppo 1.16.2, beboutit503.cppo 1.17.1) had their scripts run together after a reboot; the 1.15.3 one only knew two extension IDs, found no other copy beside BeboutItSolutions.cppo, and ran its full cleanup — deleting the state file (every provider record, roles, the host ID that names stored keys), the account stores and the window copies (conversation history was moved to ~/.claude first and survived; one account's login was handed back, the other's lost). Now:
  • A usage lease (~/.config/cppo/in-use, refreshed hourly while CPPO runs, under any extension ID): the uninstall script touches nothing while the lease is under 30 days old — whatever other copies it does or doesn't recognise. A deliberate uninstall therefore leaves CPPO's data in place until CPPO has been unused for 30 days (the README says how to clean up sooner).
  • A state backup (~/.config/cppo/state.backup.json: providers, roles, accounts, host ID; no secrets), outside everything older scripts remove. If the main state file is missing, corrupt or unreadable, CPPO restores from the backup (self-healing on the next write) and tells you. The one-time migration no longer runs when a backup exists, and a missing backup is created at start.
  • Reuse of orphaned Codex sign-ins: adding a Codex provider with its own sign-in offers any sign-in folder on the host that no provider points at any more, showing the ChatGPT account it belongs to, before asking you to sign in again.
• README: the uninstall timing, the lease and its 30-day consequence, the ~/.config/cppo files, and why uninstalled-but-pending old copies are dangerous.
