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.

What is Apache Arrow Rust?

Arrow Rust cuts release candidates on three older lines at once.

Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.

Apache OpenNLP vs Apache Arrow Rust: editorial side-by-side

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.

A5.0

Arrow Rust cuts release candidates on three older lines at once.

◆ Current state

Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.

◆ Where it's heading

The project keeps four major lines alive and patches them together, so downstream users on older Arrow versions still get fixes. Feature work stays on the 60 line.

◆ Prediction

Expect the three patch releases to publish after the vote period, and a 60.2.0 or 61.0.0 candidate to follow.
