What is Apache DolphinScheduler?
A slow, deliberate release train that keeps widening its cloud-task surface
DolphinScheduler ships on a multi-month cadence, with 3.4.2 (June 2026) and 3.4.1 (March 2026) as the recent stable points. The work is split between DSIP design proposals, new task plugins, and operator-facing hardening. Nothing in the window suggests a rewrite; this is a mature orchestrator accreting integrations.
What is PEIMAN2?
PEIMAN2 cut its annotation database loose from its release cycle without breaking CRAN.
PEIMAN2 does enrichment analysis over post-translational modifications, testing whether a protein list is enriched for particular PTMs against UniProt-derived annotations, with translation functions bridging to mass spectrometry workflows. Its answers are only as current as its bundled database, and until June that database could only be refreshed by releasing a new package version. Version 1.1.0 changes that.

◆ Current state
DolphinScheduler ships on a multi-month cadence, with 3.4.2 (June 2026) and 3.4.1 (March 2026) as the recent stable points. The work is split between DSIP design proposals, new task plugins, and operator-facing hardening. Nothing in the window suggests a rewrite; this is a mature orchestrator accreting integrations.
◆ Where it's heading
The consistent direction is coverage of managed cloud compute — Amazon EMR Serverless joins the task-plugin catalog, following the earlier consolidation of Zeppelin, SageMaker and Kubernetes connections into a shared connection center. Alongside that, the project keeps tightening what operators can see and control at runtime: monitor-page visibility into running tasks per master/worker, configurable maximum runtime, and dispatch timeout handling for missing worker groups.
◆ Prediction
Expect the next release to add another managed-compute task plugin and continue routing its credentials through the connection center, since that is the pattern every recent integration has followed.
PEIMAN2
0.0INFRA · APIS
PEIMAN2 cut its annotation database loose from its release cycle without breaking CRAN.
◆ Current state
PEIMAN2 does enrichment analysis over post-translational modifications, testing whether a protein list is enriched for particular PTMs against UniProt-derived annotations, with translation functions bridging to mass spectrometry workflows. Its answers are only as current as its bundled database, and until June that database could only be refreshed by releasing a new package version. Version 1.1.0 changes that.
◆ Where it's heading
The package has been moving from a fixed snapshot toward versioned, user-selectable data. Earlier releases updated the bundled database in place — 1.0.0 shipped the March 2025 version and said little else — which meant the annotation vintage was whatever the package version implied. Now update_peiman_database() downloads and caches external database files and UniProt PTM lists, enrichment workflows take a database_version argument, and the mass-spec translators take a ptmlist_version, so an analysis can pin a dated database rather than a package release. The CRAN-safe default is preserved deliberately: loading, examples and checks still use the bundled internal data and need no network.
◆ Prediction
Version pinning is now expressible but the release notes do not describe how a chosen version is recorded in output, so surfacing the active database version in results is the natural companion. The database and the UniProt PTM list are versioned separately, which leaves room for a combined manifest.
