What is Fulcrum?
Fulcrum is retiring Google Maps for Esri and stabilising the ArcGIS stack behind it.
The legacy Google Maps engine is being retired on 1 September 2026, with any organisation still defaulting to it switched over automatically. The mobile releases since are consolidation on the replacement: ArcGIS SDK 300.0.0, restored styling on offline ArcGIS feature layers, better basemap loading, and fixes to location-button behaviour on both platforms. iOS 2607.3.0 also swapped ONNX for a different on-device inference format.
What is Apache SeaTunnel?
SeaTunnel can finally split one large file across readers — and hasn't shipped since March.
The 2.3.13 release in March is by far the densest in this window: parallel splitting of large files for HDFS, local CSV/text/JSON and logical Parquet splits, CDC source schema evolution on the Flink engine, a checkpoint API with configurable minimum pause, and new connectors for DuckDB, Lance, AWS DSQL and HugeGraph. The releases before it were thinner — 2.3.12 and 2.3.11 are dominated by documentation, much of it Chinese translations of existing connector pages, and 2.3.9 and 2.3.8 are bug fix rollups.

Fulcrum is retiring Google Maps for Esri and stabilising the ArcGIS stack behind it.
◆ Current state
The legacy Google Maps engine is being retired on 1 September 2026, with any organisation still defaulting to it switched over automatically. The mobile releases since are consolidation on the replacement: ArcGIS SDK 300.0.0, restored styling on offline ArcGIS feature layers, better basemap loading, and fixes to location-button behaviour on both platforms. iOS 2607.3.0 also swapped ONNX for a different on-device inference format.
◆ Where it's heading
This is a forced migration being executed carefully — the map engine is the field app's core dependency, and each release since the announcement has fixed something in the ArcGIS path rather than adding capability. The pace of small mobile releases suggests they are clearing defects ahead of the September cutover rather than working to a feature roadmap.
◆ Prediction
Expect continued ArcGIS-focused fix releases on both platforms through the September cutover, with feature work resuming only once the Google Maps default is gone.

SeaTunnel can finally split one large file across readers — and hasn't shipped since March.
◆ Current state
The 2.3.13 release in March is by far the densest in this window: parallel splitting of large files for HDFS, local CSV/text/JSON and logical Parquet splits, CDC source schema evolution on the Flink engine, a checkpoint API with configurable minimum pause, and new connectors for DuckDB, Lance, AWS DSQL and HugeGraph. The releases before it were thinner — 2.3.12 and 2.3.11 are dominated by documentation, much of it Chinese translations of existing connector pages, and 2.3.9 and 2.3.8 are bug fix rollups.
◆ Where it's heading
Two things are happening at once. The engine is getting faster on the shapes that actually stall a pipeline — a single enormous file, a schema that changed under a running CDC job — and the connector catalogue keeps widening toward analytical and vector-adjacent stores rather than more transactional databases. But the cadence has stretched: releases used to land every two to three months, and nothing has shipped in nearly five.
◆ Prediction
Expect the split-and-parallel-read work started for files to extend to more source connectors, since it is the change with the broadest effect on throughput. The release gap is the open question — these entries show a lengthening interval without indicating whether a 2.4 line is being prepared behind it.
