What is GitHub?

GitHub sets a December 8 cutoff for ARM32 Actions runners and opens AI Scan to the API.

GitHub's week splits between Copilot supply and platform upkeep. Claude Fable 5.2 and Gemini 4 Carbon reached general availability in Copilot, issue types reached personal-account repositories, and enterprise GitHub Apps can assign Copilot seats. Since then it has added REST control over code scanning's AI Scan, a Cloudflare service-token detector and direct links to public monitoring alerts, and announced that hosted Actions runners stop running ARM32 jobs on December 8.

What is Nebula?

Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.

Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.

GitHub sets a December 8 cutoff for ARM32 Actions runners and opens AI Scan to the API.

◆ Current state

GitHub's week splits between Copilot supply and platform upkeep. Claude Fable 5.2 and Gemini 4 Carbon reached general availability in Copilot, issue types reached personal-account repositories, and enterprise GitHub Apps can assign Copilot seats. Since then it has added REST control over code scanning's AI Scan, a Cloudflare service-token detector and direct links to public monitoring alerts, and announced that hosted Actions runners stop running ARM32 jobs on December 8.

◆ Where it's heading

Two deadlines now land on December 8: Dependabot alerts pausing on year-idle repositories and the end of ARM32 job execution on hosted runners. GitHub is pruning what it supports while putting its AI security features behind APIs that organizations can script.

◆ Prediction

Expect AI Scan to move from public preview toward general availability with more organization-level controls, and more retirement notices timed around December 8.

Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.

◆ Current state

Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.

◆ Where it's heading

The IPv6 work has moved from security fixes to per-platform correctness, and 1.12 turns to throughput. Offloading starting as opt-in, with a stated plan to make it default, sets up the next release cycle.

◆ Prediction

Expect 1.12.x patches for offloading edge cases, and a later release that turns offloading on by default as announced.
