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 Hex?

Hex's agent now builds complete projects from chat — and is pipelineable via CLI

Hex has completed the pivot from data notebook to AI-first analytics environment. The agent can now build entire Hex projects from a single chat prompt — handling notebook creation, data connections, and generative apps — while also exposing its capabilities programmatically via CLI and API. Enterprises have gained BYOK (bring your own AI provider), spend controls, and versioned eval suites to govern model usage at scale. The generative app surface is the fastest-moving piece, receiving targeted chart controls, direct text editing, and Slack-thread context in rapid succession.

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.

Hex's agent now builds complete projects from chat — and is pipelineable via CLI

◆ Current state

Hex has completed the pivot from data notebook to AI-first analytics environment. The agent can now build entire Hex projects from a single chat prompt — handling notebook creation, data connections, and generative apps — while also exposing its capabilities programmatically via CLI and API. Enterprises have gained BYOK (bring your own AI provider), spend controls, and versioned eval suites to govern model usage at scale. The generative app surface is the fastest-moving piece, receiving targeted chart controls, direct text editing, and Slack-thread context in rapid succession.

◆ Where it's heading

The direction is agent-as-primary-interface: Hex is systematically shifting the interaction layer from 'notebook with AI help' to 'chat prompt builds the entire project,' with the notebook itself becoming an implementation detail the agent manages. CLI and API exposure makes Hex a component in automated data pipelines, not just a GUI tool. Eval suite versioning signals they're building governance infrastructure for teams that need to audit and reproduce AI-generated outputs — a layer most rivals haven't formalized. BYOK and multi-model support (Claude Opus 5, GPT-5.6 Sol/Terra/Luna, Kimi K2.7, Fable 5) signal a model-agnostic platform bet rather than vertical integration with a single provider.

◆ Prediction

The next likely move is scheduled or triggered agent runs — Hex already has CLI/API access and fast mode; the missing piece is cron or pipeline-triggered agent jobs without a human in the loop. Structured approval workflows for agent-built projects (beyond the current 'skip approvals' opt-out) are a plausible follow-on as enterprise procurement requires reproducible controls.
