What is Linkerd?

Linkerd publishes an outside threat model of the mesh, with steps for operators.

Linkerd's feed has been quiet since the 2.20 release in June, which added rate-limit-aware load balancing and cut memory use. The 10 November post reports what an independent threat model found in Linkerd and what operators should do next; the feed carries only the title, so the specific findings are not visible here. Most other recent posts are operational explainers rather than releases.

What is Apache OpenNLP?

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

2.5

Linkerd publishes an outside threat model of the mesh, with steps for operators.

◆ Current state

Linkerd's feed has been quiet since the 2.20 release in June, which added rate-limit-aware load balancing and cut memory use. The 10 November post reports what an independent threat model found in Linkerd and what operators should do next; the feed carries only the title, so the specific findings are not visible here. Most other recent posts are operational explainers rather than releases.

◆ Where it's heading

The project keeps leaning on security and operational trust: post-quantum mTLS by default in 2.19, tuning in 2.20, and now an external review of its attack surface. The emphasis is on making an existing mesh safer to run rather than adding new surface.

◆ Prediction

Expect hardening changes or new default settings tied to the threat model findings in the next stable or edge release; the entry does not say which components are affected.

A5.0

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

◆ Current state

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

◆ Where it's heading

The 3.0 milestones combined security hardening (deserialization and XXE fixes, model-loading allowlists) with new text tooling such as the Unicode normalization engine and a SymSpell spell checker, while 2.5.x added RoBERTa inference through ONNX Runtime. With 3.0.0 out, the 2.5 line is likely to move to backports only, and new work should land on 3.x.

◆ Prediction

Expect a 3.0.1 patch and continued 2.5.x security backports; whether 1.9.x gets further releases is unclear from these entries.
