SUMMARY:⚑ GitHub: Copilot Business and Enterprise: a new default policy s
 tarts deciding every eligible generally available feature an administrator
  has left Unconfigured — and the default is Enabled
DESCRIPTION:Copilot Business and Enterprise: a new default policy starts de
 ciding every eligible generally available feature an administrator has lef
 t Unconfigured — and the default is Enabled\n\nBEFORE THIS DATE: Adminis
 trators: before October 22\, set 'Default policy for new features' (AI Con
 trols → Copilot) to Enabled\, Disabled or Let organizations decide\, or 
 configure each eligible feature explicitly. GitHub's docs: 'If you don't t
 ake action\, unconfigured features will be enabled on October 22.'\n\nCave
 at: About feature access\, not price. GitHub states explicit decisions are
  preserved and preview features stay opt-in\; the policy also covers the C
 opilot Code Review policy and the MCP servers in Copilot policy. Which fea
 tures count as eligible is set by GitHub's docs and can change.\n\nAuthori
 tative document (GitHub Docs: default availability of Copilot features and
  models): https://docs.github.com/en/copilot/concepts/enterprise/default-a
 vailability\nAnnounced in: https://github.blog/changelog/2026-09-24-defaul

DESCRIPTION:GitHub Copilot deprecates GPT-5.5\, GPT-5.4\, GPT-5.4 mini\, GP
 T-5 mini\, Gemini 3.7 Flash and Grok 4.5 across all Copilot experiences\n\
 nMOVES TO: GitHub's suggested alternatives: Gemini 3.8 Flash for Gemini 3.
 7 Flash\, GPT-5.6 Sol for GPT-5.5 and GPT-5.4\, GPT-5.6 Luna for GPT-5.4 m
 ini and GPT-5 mini\, Grok 4.6 for Grok 4.5.\n\nBEFORE THIS DATE: Repoint a
 ny Copilot workflow\, custom agent or saved setting that names one of the 
 six. Business and Enterprise administrators who turned off the global mode
 l default\, or explicitly disabled an alternative\, must enable it themsel
 ves\; otherwise GitHub says the alternatives are enabled automatically.\n\
 nCaveat: A retirement from one tool\, not from the models' makers: OpenAI'
 s own GPT-5.5 retirement (October 14\, from ChatGPT and Codex) 'does not a
 pply to the OpenAI API'\, and OpenAI names GPT-6 Sol there\, not GPT-5.6 S
 ol. GitHub's supported-models page\, read the same evening\, carries the O
 ctober 2 retirements and no 2026-10-19 entry.\n\nAuthoritative document (G

SUMMARY:⚑ GitHub: GitHub Copilot deprecates Claude Opus 4.7\, Gemini 3.5

DESCRIPTION:GitHub Copilot deprecates Claude Opus 4.7\, Gemini 3.5 Flash\, 
 Gemini 3.6 Flash and Kimi K2.7 Code across all Copilot experiences\n\nMOVE
 S TO: Claude Opus 5 for Opus 4.7\, Gemini 3.8 Flash for both Gemini Flash 
 models\, Kimi K3 for Kimi K2.7 Code — GitHub's suggested alternatives.\n
 \nBEFORE THIS DATE: Copilot Business and Enterprise administrators: enable
  the alternative models in Copilot model policies before the date — GitH
 ub's notice says they may need to\, and until they do users lose the old m
 odel without getting the new one.\n\nCaveat: A retirement from ONE tool\, 
 not from the model's maker: Anthropic's deprecations page lists claude-opu
 s-4-7 as Active with a retirement not sooner than April 16\, 2027\, and Go
 ogle lists no date for its Gemini 3.x Flash models. The models remain avai
 lable elsewhere\; they leave Copilot.\n\nAuthoritative document (GitHub ch
