+## v1.4.0 [2025-09-22]
+_What's new_
+- Updated the `tailpipe` connection to support the new Tailpipe v0.7.0 DuckLake backend. ([#889](https://github.com/turbot/powerpipe/issues/889))  
+  **Note:** When using Powerpipe with Tailpipe v0.7.0, existing Tailpipe data must be migrated to DuckLake **before** running a dashboard that uses a Tailpipe backend. Data can be migrated by running `tailpipe query`.
+- Updated pipe-fittings to v2.7.0. ([#760](https://github.com/turbot/pipe-fittings/issues/760))
+  **Note:** For CentOS/RHEL users, the minimum supported version is now **CentOS Stream 10 / RHEL 10** due to `libstdc++` library compatibility.
