Hugging Face Tau 0.4.2 adds session bookmarks and live Codex model discovery
Hugging Face released Tau 0.4.2, adding persistent per-entry labels for bookmarking moments in the session tree, first-class custom_message entries for extension-injected model context, and live discovery of OpenAI Codex subscription model catalogs so new models can be selected without waiting for a Tau release. It also fixes streamed reasoning ordering and Anthropic-compatible stream handling.
