# April 2026

> New ways to investigate telemetry and build on your calculated metrics

April 2026 ships a rebuilt Explore workspace, the ability to use Calculated Channels in Rule logic, and support for referencing Calculated Channels within other Calculated Channel calculations.

## <Badge size="lg" shape="rounded" color="green">New</Badge> Investigate telemetry in one workspace

Skip the back-and-forth between tools when investigating telemetry. Open the new [Explore](/documentation/reference/explore-settings) as Sift's default workspace, shaped around your everyday workflows.

## <Badge size="lg" shape="rounded" color="green">New</Badge> Alert on every Calculated Channel

Catch problems in every metric your team calculates. Feed any [Calculated Channel](/documentation/reference/calculated-channel-settings) into a Rule and reuse the same alert logic you already rely on.

## <Badge size="lg" shape="rounded" color="green">New</Badge> Build calculations on top of calculations

Cut duplicate work and keep every dependent metric in sync. Drop any existing [Calculated Channel](/documentation/transform/create-a-derived-signal#create-a-derived-signal) into a new calculation, and updates flow through automatically.
