What is KubeVirt?

KubeVirt 1.10 reaches beta with 1,345 changes from 94 contributors.

KubeVirt runs a long pre-release cycle per minor version. The 1.9 line went from alpha in May through three release candidates in July, and 1.10 opened with an alpha in early September, then reached beta.0 on October 13 with 1,345 changes from 94 contributors since 1.9.1. The 1.9.0 final and 1.9.1 do not appear in the feed, so the release notes visible here are mostly pre-release headers with change and contributor counts.

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.

KubeVirt 1.10 reaches beta with 1,345 changes from 94 contributors.

◆ Current state

KubeVirt runs a long pre-release cycle per minor version. The 1.9 line went from alpha in May through three release candidates in July, and 1.10 opened with an alpha in early September, then reached beta.0 on October 13 with 1,345 changes from 94 contributors since 1.9.1. The 1.9.0 final and 1.9.1 do not appear in the feed, so the release notes visible here are mostly pre-release headers with change and contributor counts.

◆ Where it's heading

Each cycle draws 70 to 110 contributors and follows the same alpha, beta, release-candidate path over about three months. The 1.10 beta's notable changes begin with Istio sidecar handling, but the feed exposes little of the feature list.

◆ Prediction

Following the 1.9 pattern, 1.10 release candidates should be the next entries; the date of 1.10.0 final is unclear from the feed.

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.
