The one thing
01Claude Code 2.1.260 fixes Fable 5.1 cache and effort mid-session; npm latest is 2.1.260.
v2.1.260: fullscreen /diff panel beside the chat; /cost and status prompt_cache name why a cache missed; /effort on Fable 5.1 no longer busts the prompt cache mid-session; Fable tool-result context is cached again (it was re-sent uncached every tool turn); model: fable agents honour [1m] on ANTHROPIC_DEFAULT_FABLE_MODEL; /model shows Fable 5.1 for orgs that have it. The 2.1.259 Bash Read() deny expansion is reverted — it blocked npm run build under Read(.//build/).12
npm dist-tags: latest/next 2.1.260, stable still 2.1.236.2 Copilot adds Gemini 3.8 Flash (intro pricing through 31 Dec 2026) and schedules Gemini 3.5/3.6 Flash, Kimi K2.7 Code, and Claude Opus 4.7 off on 2 Oct 2026.34

The conversation
01Fable 5.1 day-three is cache economics and pin hygiene; the new ships are Claude Code 2.1.260 and Copilot's Gemini/deprecation pair.67
- openai/codexPrimary
rust-v0.153.1 adds GPT-6-Astra via API without changing the default or the picker; 0.153.2 only corrects the Fast-tier copy from 1.5x to 2x. Pin ≥0.153.1 if you configure Astra.89

Codex 0.153.1 is the Astra pin; 0.153.2 is copy only. Goose 1.49.0 if you want the desktop auto-updater. Outages were weather with duration, not a pin change.
