• Added --input-format stream-json to print mode, which reads newline-delimited JSON prompts from stdin and runs one turn per message in a single conversation, so a driver can keep a session open.
• Added a rules: key to markdown agent frontmatter, so an agent can name rule files directly instead of inheriting your whole rule tree; a rule named this way always applies.
• Added plugin support for a top-level rules.json, so a plugin can declare the rule files it ships the same way it already declares its skills.
• Added a more specific hint on the spinner line, which now names the tool call the agent is currently running.
• Fixed the CLI aborting at startup on hosts that preload their own allocator through LD_PRELOAD, such as Cloud TPU VM images, where it died before the interface appeared.
• Fixed personal accounts hitting a resource-exhausted error at startup when saved credentials were restored from the system keyring, and cut the repeated account checks that followed.
• Fixed your billing project, and the license tier it selects, being lost when the CLI restarted and restored saved credentials from the system keyring.
• Fixed a spurious "Out of credits" message for enterprise users signed in through Application Default Credentials.
• Fixed the /model picker cutting off models, and its own header, on terminals too short to show every model; the list now scrolls.
• Fixed the /model picker misaligning its columns for model names that are not plain ASCII, by measuring column widths in display cells rather than bytes.
• Fixed the spinner line flickering to a generic label between quick tool calls.
• Fixed streamed text corrupting non-ASCII characters into replacement characters, in both the interactive display and --output-format stream-json text deltas.
• Fixed artifacts written into a subdirectory of a conversation's artifact directory, such as scratch/, never appearing in the artifact list.
• Fixed reading a .wav file failing as an unsupported media type, by normalizing non-canonical MIME types such as audio/wave before they reach the model.
