What is ROOT?

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.

What is Chord?

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.

ROOT vs Chord: editorial side-by-side

R
ROOT
ANALYTICS
5.0

ROOT 6.40 LTS patches CMake 4.4 compatibility and 25+ tracked issues in one drop.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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's AI layer gains persistent team memory and write access to the CDP — it can now build audiences mid-conversation.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
