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 Heroku?

Runtime bumps fill the changelog; the managed Postgres line is where Heroku actually moves.

Day to day, Heroku's changelog is language-runtime upkeep: Python, Node, Ruby, Go, PHP, JRuby and .NET point releases, buildpack refreshes for Pipenv and uv, and periodic rebuilds of the Heroku-22, Heroku-24 and Heroku-26 stacks now maintained in parallel. The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.

Apache OpenNLP vs Heroku: 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.

Runtime bumps fill the changelog; the managed Postgres line is where Heroku actually moves.

◆ Current state

Day to day, Heroku's changelog is language-runtime upkeep: Python, Node, Ruby, Go, PHP, JRuby and .NET point releases, buildpack refreshes for Pipenv and uv, and periodic rebuilds of the Heroku-22, Heroku-24 and Heroku-26 stacks now maintained in parallel. The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.

◆ Where it's heading

The platform is running two clocks at once. One is a near-daily maintenance cadence that keeps supported runtimes current and rarely changes behaviour. The other is a deliberate, publicly staged lifecycle for the data services, where a major version is walked from beta to GA and the version three releases behind is retired in the same announcement. Kafka is on the same track, with 2.8 and 3.7 deprecations and a revised version-support policy posted in late July.

◆ Prediction

Given that Postgres 15's deprecation was announced alongside 18's general availability, the next concrete step is a published end-of-life date and forced-upgrade window for Postgres 15. The runtime bumps will continue at their current weekly rhythm.
