What is LaunchDarkly?
LaunchDarkly is moving experiment analysis into the customer's own warehouse.
April's work runs on two tracks. Warehouse-native experimentation reached both Redshift and Databricks within a day of each other, letting teams run experiments in LaunchDarkly while metrics compute inside their own warehouse, with automated health checks added for those connections. Separately, the React SDK shipped a ground-up v4 rewrite on the new JavaScript client, and flags gained the ability to restore a previous version from change history.
What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.

LaunchDarkly

LaunchDarkly is moving experiment analysis into the customer's own warehouse.
◆ Current state
April's work runs on two tracks. Warehouse-native experimentation reached both Redshift and Databricks within a day of each other, letting teams run experiments in LaunchDarkly while metrics compute inside their own warehouse, with automated health checks added for those connections. Separately, the React SDK shipped a ground-up v4 rewrite on the new JavaScript client, and flags gained the ability to restore a previous version from change history.
◆ Where it's heading
The experimentation story is the one that matters. Rather than pulling customer event data into LaunchDarkly to analyse it, LaunchDarkly is computing where the data already lives — which sidesteps the data-movement and governance objections that stall experimentation platforms in larger companies. Shipping Redshift and Databricks back to back, then immediately adding connection health checks, is the pattern of a capability being made operational rather than demonstrated.
◆ Prediction
Expect the remaining major warehouses to follow the same integration pattern, and more tooling around connection reliability as the warehouse becomes a dependency in the experiment path. The SDK rewrite suggests the other client SDKs will be consolidated onto the same JavaScript core.
Merge

Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
