Codex CLI 0.151.0-alpha.7

• [new] TUI diff rendering includes a dedicated preview path for reviewing changes in the interface.
• [new] Config supports exclude_slash_tmp for controlling tmp-related slash behavior.
• [new] Recognizes the o1 model identifier alongside existing models.
• [changed] Filesystem sandbox context carries additional detail for how sandbox state is described and enforced.
• [changed] Environment info reporting is expanded with more fields for runtime/context metadata.
• [changed] Remote plugins can advertise and negotiate capabilities more explicitly.
• [removed] Drops several older notification/event paths (including collab wait-end and MITM hook-denied style signals) as the event surface is trimmed.

Under the hood

• Apps and marketplace-related response types were reshaped (installed-apps summaries and related read models) toward a clearer apps/plugins surface.
• Thread APIs grow typed responses for unarchive, unsubscribe, usage query, and background-terminal listing.
• Account/rate-limit modeling adds reset-credit details and related response types; token usage can be expressed in daily buckets.
• New request/response shapes land for config bundles and secrets, plus lighter daemon/settings and release-info plumbing.
• Tools modeling introduces a v2-shaped tools payload path.
• Sandbox/network control picks up a CODEX_SANDBOX_NETWORK_DISABLED-style environment option; CIWS-related proxy configuration is also present for controlled environments.
• Session handling can work with session ID lists rather than a single ID where multi-session context is needed.
• Assorted legacy structs and one-off marketplace/plugin-share shapes were removed or folded into the newer models above.

Upgrade notes

• Alpha-to-alpha bump only (0.151.0-alpha.6 → 0.151.0-alpha.7). If you pin config or automation on env vars, re-check sandbox network and session-ID related settings after upgrading.
• Optional: try exclude_slash_tmp if you need to tune tmp path handling for slash commands.
