Codex CLI 0.147.0-alpha.10

• [new] Added --psp across the CLI to enable process-only PSP routing for first-party ChatGPT requests (reflected in shell completions).
• [new] codex exec-server accepts --concurrent-requests to cap how many requests are handled concurrently on each connection.
• [changed] Skills hosting and configuration paths were reworked toward a clearer host/service interface (including fragment and root handling).
• [changed] Agent plugin MCP configuration expanded, including additional server transport options (stdio, SSE, streamable HTTP).
• [changed] TUI session history handling improved with pagination support for longer threads.
• [changed] App-server / client protocol surface grew with client message and ack-style events, plus richer thread item and turn listing responses.
• [changed] Tool and token-budget configuration models were extended (including tool registry config and a broader token budget TOML shape).
• [removed] Older mode kinds Execute and PairProgramming are no longer part of the mode set.

Under the hood

• Skills moved off the previous core-skills service layout onto dedicated host, interface, and fragment modules.
• Runtime queued-item tracking and a shared tool-spec path were added to support clearer tool dispatch and session state.
• Plugin-related payloads (manifests, share context/principals) and external-agent session migration records were reshaped for upcoming plugin and import flows.
• Model cache and model metadata structures were refreshed; assorted exec/filesystem and elicitation payload types were tightened or renamed.
• OpenTelemetry exporter wiring favors OTLP gRPC over the previous OTLP HTTP internal variant.
• Shell completion scripts (bash, fish, zsh) were regenerated for the new flags.
