ROOT 6.40 LTS patches CMake 4.4 compatibility and 25+ tracked issues in one drop.
ROOT 6.40 LTS is in active patch maintenance. The 6.40.04 update fixed a CMake 4.4 compatibility break that was blocking new builds, alongside 25+ tracked issues spanning NTuple late-extension bugs, RooFit integral correctness, GDML geometry parsing, and Minuit2 robustness. Multiple older series — 6.36, 6.32, 6.30, 6.28 — continue receiving minor patches, reflecting the long support windows typical of HEP infrastructure software.
Chord's AI layer gains persistent team memory and write access to the CDP — it can now build audiences mid-conversation.
Chord is a commerce CDP that has been systematically upgrading its AI layer, now called Ask Chord, from a Q&A interface into an operational assistant. Two structural shifts happened in the July–August window: the AI moved from read-only to write-capable (it can now build and save CDP audiences directly from a conversation), and it gained persistent team memory (context written back into the knowledge base mid-conversation, searchable in later sessions). Integrations are expanding: Gorgias is now a native data source, and OpenAI Ads has a Conversions API destination.

The 6.40 LTS capabilities — concurrent histogram filling, RDataLoader, S3/libcurl-backed I/O, experimental opt-out of auto-registration — shipped in 6.40.00 and the patch cycle is now focused on correctness and compatibility. ROOT 7's full-API future continues to be a long-horizon goal; in the near term, the project is consolidating the 6.40 LTS base.
Expect continued 6.40.x patches at this cadence, with occasional older-series backports. A 6.42 development series will eventually surface new capabilities, but there is no visible signal of its timeline from the current patch activity.

Chord is betting that the CDP's long-term value is in the AI interface, not the data infrastructure. Each release extends what Ask Chord can do without leaving the conversation: build segments, remember business definitions, act on the data store. The renaming from Copilot to Ask Chord is cosmetic; the architectural direction — an AI that learns your business context and takes actions inside the platform — is the real story. Whether the write-to-CDP capability holds up under real analyst workflows is the key validation question.
The next move is likely scheduled or trigger-based agent actions: run a cohort analysis on a cadence, surface an alert when a segment metric crosses a threshold, or draft campaign copy from CDP data. The shared team memory feature points toward a knowledge-base layer where analysts encode business rules that the AI enforces going forward.
