0.20.0

Some key fixes for Windows:

• https://github.com/openai/codex/pull/2035 the npm release of @openai/codex now runs the Rust CLI instead of falling back to the old TypeScript CLI (TypeScript code was removed from the repo in https://github.com/openai/codex/pull/2048)
• https://github.com/openai/codex/pull/2019 fixes two things for Windows:
  • fixes one class of issues with login logic by writing Python program to a temp file instead of long string arg (FYI, we are planning to replace the Python with Rust: https://github.com/openai/codex/pull/2047)
  • ignores PopKeyboardEnhancementFlags failure since not all Windows terminals support it
• https://github.com/openai/codex/pull/2042 should help/fix the Python certificates issue with codex login: https://github.com/openai/codex/issues/2044
