Codex 0.148.0 Ships Stable With `codex exec fork`, `/export` to Markdown and Bedrock as a Built-In Provider
OpenAI cut Codex rust-v0.148.0 stable on 2026-08-18 with roughly 245 commits, adding session forking via `codex exec fork`, archive/restore from the TUI resume picker, `/export` of a full TUI conversation to Markdown or clipboard, and Amazon Bedrock Runtime as a built-in provider with AWS profile and region support. Hooks can now run commands asynchronously and invoke MCP tools, and `/status` shows estimated thread credits or cost for eligible workspaces. Sandbox restrictions now fail closed on denied or unreadable paths on Linux and Windows, and the 0.149.0 alpha train opened the next day.
