openai/codex rust-v0.96.0 on GitHub

New Features

Added thread/compact to the v2 app-server API as an async trigger RPC, so clients can start compaction immediately and track completion separately. (#10445)
Added websocket-side rate limit signaling via a new codex.rate_limits event, with websocket parity for ETag/reasoning metadata handling. (#10324)
Enabled unified_exec on all non-Windows platforms. (#10641)
Constrained requirement values now include source provenance, enabling source-aware config debugging in UI flows like /debug-config. (#10568)

Fixed Esc handling in the TUI request_user_input overlay: when notes are open, Esc now exits notes mode instead of interrupting the session. (#10569)
Thread listing now queries the state DB first (including archived threads) and falls back to filesystem traversal only when needed, improving listing correctness and resilience. (#10544)
Fixed thread path lookup to require that the resolved file actually exists, preventing invalid thread-id resolutions. (#10618)
Dynamic tool injection now runs in a single transaction to avoid partial state updates. (#10614)
Refined request_rule guidance used in approval-policy prompting to correct rule behavior. (#10379, #10598)

Updated app-server docs for thread/compact to clarify its asynchronous behavior and thread-busy lifecycle. (#10445)
Updated TUI docs to match the mode-specific Esc behavior in request_user_input. (#10569)

Migrated state DB helpers to a versioned SQLite filename scheme and cleaned up legacy state files during runtime initialization. (#10623)
Expanded runtime telemetry with websocket timing metrics and simplified internal metadata flow in core client plumbing. (#10577, #10589)
