What is GeoServer?

GeoServer patches three branches at once, with the new work reserved for the 3.0 line

Three releases landed within about an hour of each other — 2.27.6, 2.28.5 and 3.0.1 — the coordinated multi-branch pattern this project uses for maintenance. The shared payload is a set of security-adjacent fixes: a GeoFence SQL query missing its spatial filter when only CLIP applies, wrong CRS axis order when clipping WFS 2.0.0 features, and the XXE vulnerability in features-templating backported to the oldest branch. Only 3.0.1 carries new capability: a Keycloak role service and security-aware GeoWebCache tile caching.

What is Libreswan?

Libreswan puts post-quantum key exchange into IKEv2 — ML-KEM 768 ships in v5.4.

Libreswan spent the last two releases on security patches, including a CVE found when the project ran an AI audit over its own codebase. v5.4 breaks that pattern: it implements RFC 9370's multiple-key-exchange machinery end to end — IKE_INTERMEDIATE, IKE_ADDITIONAL_KE and IKE_FOLLOWUP_KE — and uses it to carry ML_KEM_768 in IKE_SA_INIT and IKE_INTERMEDIATE. The rest of the release is a wide maintenance sweep across kernel integration on the BSDs, config parsing and logging.

GeoServer patches three branches at once, with the new work reserved for the 3.0 line

◆ Current state

Three releases landed within about an hour of each other — 2.27.6, 2.28.5 and 3.0.1 — the coordinated multi-branch pattern this project uses for maintenance. The shared payload is a set of security-adjacent fixes: a GeoFence SQL query missing its spatial filter when only CLIP applies, wrong CRS axis order when clipping WFS 2.0.0 features, and the XXE vulnerability in features-templating backported to the oldest branch. Only 3.0.1 carries new capability: a Keycloak role service and security-aware GeoWebCache tile caching.

◆ Where it's heading

The branch split is doing what it is supposed to. The 2.x lines get fixes and nothing else, while the 3.0 line — which broke the monolith into extensions — is where authentication and cache-security work now lands. The recurring theme across all three is access control at the data layer: GeoFence filtering, secured feature sources, and now tile caching that respects security rather than serving from an unaware cache.

◆ Prediction

Expect the next coordinated round to follow the same shape, with 3.0.2 taking further security-aware caching and identity-provider work while the 2.x branches receive only the shared fixes.

6.3

Libreswan puts post-quantum key exchange into IKEv2 — ML-KEM 768 ships in v5.4.

◆ Current state

Libreswan spent the last two releases on security patches, including a CVE found when the project ran an AI audit over its own codebase. v5.4 breaks that pattern: it implements RFC 9370's multiple-key-exchange machinery end to end — IKE_INTERMEDIATE, IKE_ADDITIONAL_KE and IKE_FOLLOWUP_KE — and uses it to carry ML_KEM_768 in IKE_SA_INIT and IKE_INTERMEDIATE. The rest of the release is a wide maintenance sweep across kernel integration on the BSDs, config parsing and logging.

◆ Where it's heading

The post-quantum work is the spine of this release and it is not experimental framing — it is standards-track RFC 9370 plus a hard dependency on NSS 3.118.1, meaning distributions have to move their crypto library before users can turn it on. Around it, the project keeps grinding on operator experience: better proposal parsing, more specific error messages, traffic selectors and DIGSIG algorithms in logs, and rate-limited logging. Experimental flags for subnet leasing and updown-config suggest the next capability additions are already staged.

◆ Prediction

Expect ML-KEM to move from supported to recommended in default proposals once NSS 3.118.1 is widely packaged, and the experimental leftaddresspool subnet leasing and per-connection debug options to stabilize in a following release.
