What is Dagster?

Dagster is turning declarative automation from an asset feature into the way the whole platform schedules work.

Dagster ships a core/libraries pair on a near-weekly cadence, and the release notes read like an engineering log: a few genuinely new capabilities per version, a long bugfix tail, and steady community contributions. The current cycle is concentrated in three places — Declarative Automation, the dbt-on-Snowflake integration, and asset health reporting. Serverless and Kubernetes deployment paths get frequent hardening.

What is rosm?

rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl

rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.

Dagster is turning declarative automation from an asset feature into the way the whole platform schedules work.

◆ Current state

Dagster ships a core/libraries pair on a near-weekly cadence, and the release notes read like an engineering log: a few genuinely new capabilities per version, a long bugfix tail, and steady community contributions. The current cycle is concentrated in three places — Declarative Automation, the dbt-on-Snowflake integration, and asset health reporting. Serverless and Kubernetes deployment paths get frequent hardening.

◆ Where it's heading

Declarative Automation is expanding past its original asset scope: it can now launch entire jobs from a condition, with its own evaluation history tab. In parallel, the component model is becoming the packaging unit for integrations, with SnowflakeDbtProjectComponent moving from preview toward parity with DbtCloudComponent via versioned state storage. Asset health is being made more honest — failures pending an automatic retry now warn rather than report degraded, so alerts stop crying wolf.

◆ Prediction

Declarative Automation for jobs is the clearest candidate to graduate from preview, and SnowflakeDbtProjectComponent is following the same preview-to-parity path. Expect the component surface to keep absorbing integrations that were previously bespoke code.

rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl

◆ Current state

rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.

◆ Where it's heading

The package is being brought back from dormancy on modern foundations rather than extended. rgdal's retirement forced the issue, and the maintainer used it to replace the download path with concurrent curl requests and to hand geometry handling to wk. What follows is consolidation: dead built-in tile sources are being tested around rather than replaced, which leaves the source registry as the obvious unfinished edge.

◆ Prediction

The dead Bing and Stamen endpoints are currently skipped rather than fixed, so the next release most likely prunes or re-points the built-in tile source list and continues retiring the silently deprecated functions.
