Signal / 001 — New coding tools, SSH changes, and a solo trip to Arrakis

SYSVOID SIGNAL // 22 SEPTEMBER 2026

Three updates for the next time you open the terminal—or close it and launch a game.

BUILD // More model choices in Copilot

GitHub has added GPT-6 Sol and GPT-6 Luna to Copilot. GitHub describes Sol as a balanced option for coding work and Luna as a lighter option for smaller tasks. Access depends on your plan, and the rollout is gradual. For builders, the useful detail is having more choice about which model handles which job.

SYSTEMS // GitHub announces SSH changes

GitHub says new RSA SSH keys uploaded from October 14 must be at least 3072 bits. It also announced a newer post-quantum key-exchange option and plans to retire older SSH algorithms. If your workflow connects over SSH, read the compatibility notes before the changes arrive; Git remotes using HTTPS are unaffected.

PLAY // Arrakis gets a solo option

Dune: Awakening has arrived on Xbox Series X|S alongside an update that adds a full single-player mode. Funcom says solo players can adjust settings such as resource harvesting, XP, and item durability. That gives anyone drawn to the survival sandbox another way to explore it at their own pace.
