CloudStack ships two LTS branches in lockstep and publishes nothing but pointers
A side-by-side editorial comparison of authentik and stRoke — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Split itself in two, keeping the stroke-trial functions and exporting the rest
stRoke is now deliberately narrow: functions for handling clinical stroke trial data, mostly questionnaire scoring such as pase_calc() for PASE and mfi_calc() for MFI domain scores. It reached that state by subtraction — the 24.10.1 release moved eight general-purpose helpers out to a separate package, project.aid, and stated the change of focus in the notes. The most recent release, 25.9.1, is an eighty-character note about accommodating upcoming ggplot2 changes.

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.
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.
stRoke is now deliberately narrow: functions for handling clinical stroke trial data, mostly questionnaire scoring such as pase_calc() for PASE and mfi_calc() for MFI domain scores.

The most recent release, 25.9.1, is an eighty-character note about accommodating upcoming ggplot2 changes.
The package uses calendar versioning and its history is one of scope being repeatedly redrawn: ds2dd() went to REDCapCAST in 2023, then the general data and project management helpers went to project.aid in 2024. What remains is domain-specific and slow-moving, and the past eleven months produced a single compatibility release. The maintainer's visible effort has moved to the sibling packages.
Expect further questionnaire scoring functions if the maintainer's own trials need them and compatibility releases otherwise; on the pattern set in 24.10.1, more of the remaining general-purpose functions could still migrate to project.aid.
