What is authentik?

authentik 2026.8 ships: Actors, domain-joined Agents, and a push past browser-mediated SSO

2026.8.0 is out, closing a seven-candidate train that ran through early August. The GA tag itself is the last cherry-pick batch — SCIM group membership removals, a proxy redirect that preserves query strings, session deletion on user deactivation — but the release it finalizes is where the substance lives: an Actors primitive in core, an enterprise Agent requiring a domain join and its own API scope, OAuth2 token exchange delegation, and a CAS source integration.

What is campsis?

Campsis breaks its API on purpose: snake_case throughout, RxODE compatibility cut loose.

Campsis runs clinical-trial simulations from pharmacometric models, sitting on mrgsolve and rxode2 as interchangeable engines, with the sibling package Campsismod supplying the model object layer. Version 1.9.0 is the release where the suite stops carrying its history: the whole API migrates to snake_case, backward compatibility with the old RxODE package is removed, and result processing is refactored into output functions that can be applied as a collection, with an NCA table the first substantial one. Campsismod made the same snake_case move a week earlier, so this is a suite-wide rename rather than one package's decision.

authentik 2026.8 ships: Actors, domain-joined Agents, and a push past browser-mediated SSO

◆ Current state

2026.8.0 is out, closing a seven-candidate train that ran through early August. The GA tag itself is the last cherry-pick batch — SCIM group membership removals, a proxy redirect that preserves query strings, session deletion on user deactivation — but the release it finalizes is where the substance lives: an Actors primitive in core, an enterprise Agent requiring a domain join and its own API scope, OAuth2 token exchange delegation, and a CAS source integration.

◆ Where it's heading

Two threads converge in this major. The identity surface keeps broadening at the protocol edge — CAS, WS-Fed, token exchange delegation, on-behalf-of — while the enterprise tier grows an endpoint story that reaches machines and devices rather than browser sessions. The RC train's shape reinforces it: six candidates fired in one day on CI and docs, then one heavy candidate carrying the features, then a fix-only close. That is release engineering hardened around a major, not a routine point release.

◆ Prediction

With Agents and Actors now GA rather than cherry-picks, the next branch should build out what they enable — device-conditioned policies or agent-brokered credentials — while 2026.8.x settles into backport patches.

Campsis breaks its API on purpose: snake_case throughout, RxODE compatibility cut loose.

◆ Current state

Campsis runs clinical-trial simulations from pharmacometric models, sitting on mrgsolve and rxode2 as interchangeable engines, with the sibling package Campsismod supplying the model object layer. Version 1.9.0 is the release where the suite stops carrying its history: the whole API migrates to snake_case, backward compatibility with the old RxODE package is removed, and result processing is refactored into output functions that can be applied as a collection, with an NCA table the first substantial one. Campsismod made the same snake_case move a week earlier, so this is a suite-wide rename rather than one package's decision.

◆ Where it's heading

The 1.8 and 1.9 releases together describe a package being made drivable from outside R. JSON interfaces arrived first for models in Campsismod 1.3.0 and for datasets in Campsis 1.8.0, then extended to scenarios, settings and study replication; the output side has now been generalised the same way, from fixed result processing to a collection of output functions applied to simulated results. Renaming every function and cutting RxODE loose is the cost of that consolidation, paid in one deliberate breaking release rather than spread across several.

◆ Prediction

With the rename and the RxODE removal behind it, the next releases should restore the rxode2 engine to the test suite, which 1.9.0 removed temporarily, and continue filling out the output-function catalogue beyond NCA. The JSON surface looks like the intended entry point for driving Campsis from outside R, though the entries do not say what is meant to consume it.
