What is authentik?

The first patch on 2026.8 is twenty-odd fixes and no new surface.

2026.8.1 is the first patch after the 2026.8 release, and the GitHub tag carries only a link to the docs. The fix list behind it is entirely correctness work: proxy outposts no longer break header parsing in non-compliant backends or double-send the host on token introspection, X-Forwarded-For now takes the rightmost untrusted IP, expression policies stop polluting the request context, and websocket subprotocol negotiation is relayed properly. New installs get a one-day default token duration. Nothing here changes what authentik can do.

What is Scalar?

Scalar's mock server learns event-driven APIs while the reference UI picks up localization

Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.

The first patch on 2026.8 is twenty-odd fixes and no new surface.

◆ Current state

2026.8.1 is the first patch after the 2026.8 release, and the GitHub tag carries only a link to the docs. The fix list behind it is entirely correctness work: proxy outposts no longer break header parsing in non-compliant backends or double-send the host on token introspection, X-Forwarded-For now takes the rightmost untrusted IP, expression policies stop polluting the request context, and websocket subprotocol negotiation is relayed properly. New installs get a one-day default token duration. Nothing here changes what authentik can do.

◆ Where it's heading

The release train is behaving as expected after a major: 2026.8.0 landed in mid-August after a long rc series, and the first patch is dominated by outpost and proxy edge cases, which is where authentik meets other people's infrastructure and therefore where the reports come from. The security-adjacent items — X-Forwarded-For parsing, expression context isolation, a shorter default token life — are hardening rather than capability.

◆ Prediction

Patch releases on a fresh major usually run in a short series, so a 2026.8.2 with the remaining outpost reports is the likely next entry. The tag body links to docs rather than describing anything, so nothing further is stated.

Scalar's mock server learns event-driven APIs while the reference UI picks up localization

◆ Current state

Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.

◆ Where it's heading

AsyncAPI is the clear investment across all three packages — rendered in the reference, filterable in navigation, and now mockable as live event streams. The client and reference lines otherwise trend toward extension points and polish rather than new surface.

◆ Prediction

Expect AsyncAPI support to complete the loop by reaching the API client, so event-driven APIs can be exercised interactively the way REST endpoints already are.
