What is pgBackRest?

pgBackRest 2.60 now stops a restore when a page checksum is bad

pgBackRest 2.60.0, released October 18, changes a default: restore now errors and stops if a restored file has an invalid page checksum, leaving the cluster unable to start until the restore is rerun, and expire refuses to proceed if the oldest retained backup would contain checksum errors. Setting checksum-page-error=n returns to warnings. The release also adds GCS Workload Identity Federation and prefetch for object-store reads. Two weeks earlier 2.59.3 fixed a bug that could generate weak encryption subkeys and salts when system random data failed.

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.

pgBackRest vs Apache OpenNLP: editorial side-by-side

P5.0

pgBackRest 2.60 now stops a restore when a page checksum is bad

◆ Current state

pgBackRest 2.60.0, released October 18, changes a default: restore now errors and stops if a restored file has an invalid page checksum, leaving the cluster unable to start until the restore is rerun, and expire refuses to proceed if the oldest retained backup would contain checksum errors. Setting checksum-page-error=n returns to warnings. The release also adds GCS Workload Identity Federation and prefetch for object-store reads. Two weeks earlier 2.59.3 fixed a bug that could generate weak encryption subkeys and salts when system random data failed.

◆ Where it's heading

The project is moving from reporting corruption to refusing to continue past it, a stricter stance that fits the root restriction in 2.59.0. Cloud identity continues too, with GCS joining the Azure and S3 work. Underneath, the code generation, documentation tools and test harness have moved from C and Perl to Python, and a documented release schedule and new website show the project formalizing how it runs.

◆ Prediction

Patches tracking PostgreSQL 19 should continue, as 2.59.2 did with 19beta4. Now that restore can fail on checksums, expect follow-up fixes or guidance for clusters where existing backups contain them.

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.
