What is RNifti?
The C++ layer under R's neuroimaging stack, closing the gaps where images stopped acting like arrays
RNifti reads and writes NIfTI and ANALYZE medical image files, exposing them to R through an internalImage class that keeps pixel data on the C++ side until it is needed. It is infrastructure: other neuroimaging packages depend on it, and much of its release history is driven by their bug reports. Recent work has been about making that lazy image type behave like a normal R array without giving up the memory advantage.
What is WorkOS?
WorkOS is building the identity layer for agents while quietly making it easy to switch to it.
WorkOS sells enterprise-readiness infrastructure — SSO, SCIM directory sync, and AuthKit — to application developers. The recent work runs on two tracks. One is a fast-moving agent stack: agent identities registering through an open protocol, a proxy that calls third-party APIs so applications never hold user tokens, and Atlas, an AI coworker that is an end-user product rather than a developer primitive. The other is adoption and developer experience, including a local API for CI/CD testing and a reversible SCIM migration bridge.

The C++ layer under R's neuroimaging stack, closing the gaps where images stopped acting like arrays
◆ Current state
RNifti reads and writes NIfTI and ANALYZE medical image files, exposing them to R through an internalImage class that keeps pixel data on the C++ side until it is needed. It is infrastructure: other neuroimaging packages depend on it, and much of its release history is driven by their bug reports. Recent work has been about making that lazy image type behave like a normal R array without giving up the memory advantage.
◆ Where it's heading
Two threads run through these releases. One extends what the package can represent — RGB arrays, complex datatypes, JSON sidecar metadata — steadily widening the file and type surface it covers. The other closes semantic holes in the deferred-loading design, where R would silently fall back on character methods because the image class had no method of its own. The 1.9.0 work is the clearest example, and it is careful to keep the memory benefit by pushing summaries into C++ rather than materialising an array.
◆ Prediction
The JSON sidecar support is flagged as R-only for now, which makes exposing it through the C++ API the most likely next step.

WorkOS is building the identity layer for agents while quietly making it easy to switch to it.
◆ Current state
WorkOS sells enterprise-readiness infrastructure — SSO, SCIM directory sync, and AuthKit — to application developers. The recent work runs on two tracks. One is a fast-moving agent stack: agent identities registering through an open protocol, a proxy that calls third-party APIs so applications never hold user tokens, and Atlas, an AI coworker that is an end-user product rather than a developer primitive. The other is adoption and developer experience, including a local API for CI/CD testing and a reversible SCIM migration bridge.
◆ Where it's heading
The agent releases fit together as one bet: if agents are going to act on users' accounts, someone has to issue their identities and hold their credentials, and WorkOS is positioning to be that party in both cases. What is notable is the pairing with go-to-market plumbing. A reversible SCIM proxy with zero downtime and safe rollbacks is not a capability story, it is a switching-cost story, and shipping it alongside the agent work suggests confidence that the platform is worth migrating onto.
◆ Prediction
Expect the agent identity and token custody pieces to converge into a single documented stack, since Pipes and Agent Registration currently solve adjacent halves of the same problem. Atlas remains the thinnest-described release and the least clear in intent.
