Huginn vs Nebula: at a glance
What is Huginn?
Huginn now waits three days before trusting a newly published gem.
Huginn has shipped near-weekly releases since August, starting with security fixes and moving into hardening and upkeep. The latest, v2026.11.01, updates bundled gems and adds a three-day cooldown before newly published gems are picked up during dependency resolution. The week before brought a Ruby 4.0.9 upgrade for a regex memory-corruption fix, a localized web UI and corrected CA trust after the eMudhra incident.
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.

◆ Current state
Huginn has shipped near-weekly releases since August, starting with security fixes and moving into hardening and upkeep. The latest, v2026.11.01, updates bundled gems and adds a three-day cooldown before newly published gems are picked up during dependency resolution. The week before brought a Ruby 4.0.9 upgrade for a regex memory-corruption fix, a localized web UI and corrected CA trust after the eMudhra incident.
◆ Where it's heading
After the August and September security advisories, the project has turned to supply-chain and runtime hygiene: trust stores, hardened CI runners and now a gem cooldown. Feature work is small and operator-facing, such as Agents page filters and the LOCALE setting.
◆ Prediction
More weekly maintenance releases are likely; the feed shows no sign of a larger feature push.
Nebula
2.5INFRA · APIS
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.
