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.

What is Strimzi?

Strimzi 1.3 starts encrypting and authenticating Kafka's internal connections.

Strimzi's feed carries release candidates rather than finals. 1.3.0-rc1 on 5 October added early-access configurable encryption and authentication for internal Kafka connections, and 1.3.1-rc1 on 29 October added Kafka 4.3.2 support and fixed concurrency issues left by the Vert.x removal. The 1.2.0 cycle before it brought Kafka 4.3.1, per-pod volume templates and permanently enabled server-side apply.

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.

5.0

Strimzi 1.3 starts encrypting and authenticating Kafka's internal connections.

◆ Current state

Strimzi's feed carries release candidates rather than finals. 1.3.0-rc1 on 5 October added early-access configurable encryption and authentication for internal Kafka connections, and 1.3.1-rc1 on 29 October added Kafka 4.3.2 support and fixed concurrency issues left by the Vert.x removal. The 1.2.0 cycle before it brought Kafka 4.3.1, per-pod volume templates and permanently enabled server-side apply.

◆ Where it's heading

Since 1.0 removed every CRD API but v1, each minor follows the same pattern: support the newest Kafka, drop the oldest, tighten operator defaults. 1.3 adds security of the cluster's internal traffic to that list.

◆ Prediction

A 1.4.0 candidate tracking the next Kafka release is the likely next entry, with the internal-security options possibly leaving early access.
