What is GitHub?

Security and governance controls catch up to the Copilot build-out

GitHub's shipping split cleanly this window: platform security and governance on one side, Copilot model rotation on the other. Credential revocation now works by token type during an incident, OAuth apps can opt into expiring tokens with refresh, and enterprise managed settings reached Copilot for JetBrains. Code Quality gained a Trends tab at the organization level, and CodeQL 2.26.3 improved JavaScript, TypeScript and Vue modeling alongside GitHub Actions queries.

What is Psi4?

Psi4 is closing the gap with ORCA on the methods that decide which code a lab installs

Psi4 ships a major version roughly annually with a trail of conda-compatibility patch releases behind each one. The 1.11 cycle is the most competitively pointed in the window: DLPNO-CCSD and DLPNO-CCSD(T) become callable methods, with cutoffs deliberately tuned to match ORCA, and ZORA arrives for scalar-relativistic core Hamiltonians. Around the science, the project spends heavily on Python-ecosystem plumbing — QCSchema v2, Python 3.14 support, and the QCArchive dependency chain that most of its patch releases exist to unbreak.

Security and governance controls catch up to the Copilot build-out

◆ Current state

GitHub's shipping split cleanly this window: platform security and governance on one side, Copilot model rotation on the other. Credential revocation now works by token type during an incident, OAuth apps can opt into expiring tokens with refresh, and enterprise managed settings reached Copilot for JetBrains. Code Quality gained a Trends tab at the organization level, and CodeQL 2.26.3 improved JavaScript, TypeScript and Vue modeling alongside GitHub Actions queries.

◆ Where it's heading

The interesting work has moved from adding Copilot surfaces to governing them. Enterprise managed settings, MCP allowlists, and per-token-type revocation are all answers to the same question — how an administrator controls an agent fleet — and they are arriving faster than the agent features themselves now. Model additions have become routine catalogue maintenance, individually low-signal.

◆ Prediction

Expect enterprise managed settings to keep extending to the remaining Copilot clients, and OAuth token expiry to move from opt-in toward default once adoption data supports it. The weekly model cadence should continue with little signal in any single addition.

Psi4 is closing the gap with ORCA on the methods that decide which code a lab installs

◆ Current state

Psi4 ships a major version roughly annually with a trail of conda-compatibility patch releases behind each one. The 1.11 cycle is the most competitively pointed in the window: DLPNO-CCSD and DLPNO-CCSD(T) become callable methods, with cutoffs deliberately tuned to match ORCA, and ZORA arrives for scalar-relativistic core Hamiltonians. Around the science, the project spends heavily on Python-ecosystem plumbing — QCSchema v2, Python 3.14 support, and the QCArchive dependency chain that most of its patch releases exist to unbreak.

◆ Where it's heading

Two things are being built at once. Scientifically, the code is filling in the local-correlation and relativistic methods that users otherwise leave for commercial packages, plus external-potential and embedding machinery that makes Psi4 usable as a QM engine inside larger workflows. Structurally, it is betting on the QCArchive stack — qcelemental, qcengine, qcmanybody, optking, qcfractal — which delivers interoperability but also means a Python packaging change downstream can force a release, as 1.10.1 and 1.10.2 both did.

◆ Prediction

The DLPNO work landed as energies only, so analytic gradients for DLPNO-CCSD are the natural next step. Expect at least one more 1.11.x patch driven by the QCFractal and pydantic constraints that the 1.11 notes flag as still unresolved for Python 3.14.
