FAQ

What is the most practical addition in 0.164.0?

The ten numbered /presets slots. Store the prompts and slash commands you retype constantly and pull them back with the keyboard menu instead of scrolling history.

Where does credential masking apply?

Per the release notes it covers supported remote Bash commands and Zsh snapshot sessions, including credentials from custom providers, and it spans logs, transcripts and approval prompts.

Is upgrading worth it?

The same release fixes session recovery after compaction, repeated --config overrides and Windows proxy authentication over Negotiate/NTLM. If you live in remote sessions behind a proxy, upgrade.

Does the Bedrock wizard being on by default force me to use Bedrock?

No. When AWS credentials are detected, the API key entry is grouped with the other AWS sign-in methods so setup happens in one pass. Nothing forces you onto Bedrock.

Does it cost anything?

The CLI itself ships from the open-source openai/codex repository at no charge. What you pay for is the underlying model usage, billed through your plan or API account.
