The one thing
01Codex 0.153.0 ships; Claude Code latest is 2.1.259 with managed MCP and headless deny.
openai/codex rust-v0.153.0: Vim undo/redo that keeps pastes and attachments, plugin CLI for remote marketplaces, optional tui.auto_recap = false, fuller TUI history, earlier half-allowance warning for Plus/Team in the ~5h window, and TUI reconnect after app-server drops without losing drafts.1
claude-code v2.1.259 adds managedMcpServers (org HTTP/SSE MCP for every user; command-shaped entries skipped) and --permission-prompts none for unattended hosts. Concurrent sessions no longer clobber ~/.claude.json; Bash Read deny rules cover option values and cd && cat compounds. npm: stable 2.1.236 / latest 2.1.259.23

The conversation
01Pins moved on Codex and Claude Code; Fable heat is still yesterday's story, measured as burn and retention, not a new GA.67
- pydantic-aiPrimary
v2.38.0 adds Fable 5.1 / Mythos 5.1, gemini-3.8-flash, VLLMProvider, and context_window on ModelProfile — one-off capabilities get a default id (compat).8
- GitHub ChangelogPrimary
Content exclusions GA in Copilot app/CLI; enterprise default model for new conversations, team-overridable.45

LocalLLaMA on Muse Spark open weights "coming soon"; ClaudeAI on Fable 5 vs 5.1 MineBench diffs — no vendor page in-window for either claim.9
pydantic-ai 2.38.0 is the library pin if you call Fable from Python. Copilot exclusions are admin config before the next agent run on app/CLI.
