Lightdash is turning BI into an app platform its users' coding agents can build against.
Lightdash's centre of gravity has moved from charts to Data Apps. In the last month apps gained the ability to call third-party HTTP APIs through a credential-injecting proxy, a generator that builds reusable chart types from a prompt, query-inspection tooling, and now a local workflow: scaffold an app with the CLI, iterate on it in your own IDE against live data, and upload the source for Lightdash to build on your instance. Around that, content as code expanded to cover dashboards, permissions, AI agents, automations and org roles, and verified content was unified with AI agents so the MCP serves one trusted source.
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.

Two threads are converging. One makes the semantic layer legible to agents - verified content and AI-verified answers share a single source of truth that the Lightdash MCP and outside assistants read from. The other makes the platform something agents can write to, with apps scaffolded locally, built by whatever coding agent the developer prefers, then shipped into a governed instance. The governance framing is carrying real weight in both, since the pitch is that data and metrics stay controlled while authoring moves outside the product.
Expect the local app workflow and content as code to fuse, so agent-driven changes to dashboards, permissions and apps arrive as pull requests against a Lightdash instance. The pieces are shipped; what these entries do not settle is how agent-authored apps get reviewed or approved before viewers see them.

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.
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.
