AddedAdded an advanced Codex model-ID selector for explicitly choosing account-gated or upstream-hidden models without forcing them into the normal model catalog
ChangedUpdated the embedded Codex runtime to 0.153.4, making GPT-6 Astra visible and the default in the bundled fallback catalog while preserving account-provided catalogs and explicit model selections
ChangedUpdated the embedded Claude ACP runtime to 0.75.1, surfacing context compaction as tool activity and rendering Claude /usage results as structured Markdown
