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 Biome?

Biome's weekly patches keep widening past JavaScript, with Tailwind the deepest thread.

Biome ships a 2.5.x patch roughly weekly, each carrying a handful of nursery rules and a long tail of formatter and parser fixes. The rule set now reaches well past JavaScript — CSS, HTML, Svelte, Vue, Astro and Tailwind all get attention inside a single release. Type-aware rules remain the expensive part, and their performance is tuned in nearly every patch.

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.

Biome

5.0

Biome's weekly patches keep widening past JavaScript, with Tailwind the deepest thread.

◆ Current state

Biome ships a 2.5.x patch roughly weekly, each carrying a handful of nursery rules and a long tail of formatter and parser fixes. The rule set now reaches well past JavaScript — CSS, HTML, Svelte, Vue, Astro and Tailwind all get attention inside a single release. Type-aware rules remain the expensive part, and their performance is tuned in nearly every patch.

◆ Where it's heading

Two expansions run at once: the languages Biome understands, and the depth of its Tailwind class parser, which has gone from flagging arbitrary values to parsing container-query variants, combinator selectors, bare-utility modifiers and the legacy important marker. Nursery is the staging area, and rules are accumulating there faster than they graduate. The HTML formatter is still absorbing whitespace edge cases, which is where a formatter earns the trust to be run on write.

◆ Prediction

The Tailwind parser work is close to supporting a coherent class sorting and linting story rather than isolated rules, and the nursery backlog will need a graduation pass before the next minor.
