LibreSpeed finished its design migration and is now hardening what it measures.
LibreSpeed spent late 2025 and early 2026 landing a rewritten frontend that had been in progress for roughly two years, moving it from a feature-switch pre-release to the default in 6.0.0. With that migration behind it, the 6.2.x line has turned to measurement itself and to deployment robustness — a dedicated connection-stability test, installable PWA packaging, and a string of Docker and asset-layout fixes.
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.
LibreSpeed spent late 2025 and early 2026 landing a rewritten frontend that had been in progress for roughly two years, moving it from a feature-switch pre-release to the default in 6.0.0. With that migration behind it, the 6.2.x line has turned to measurement itself and to deployment robustness — a dedicated connection-stability test, installable PWA packaging, and a string of Docker and asset-layout fixes.
The most interesting shift is scope. LibreSpeed was a one-shot bandwidth benchmark; 6.2.0 added a standalone stability test with live latency charting, packet-loss tracking, and CSV export, which is a different job — watching a connection over time rather than scoring it once. The 6.2.1 follow-up shows the maintainers treating measurement accuracy as the product: upload results were being inflated when a request came back with an HTTP error, and the client now waits for a successful status before starting a replacement. Deployment work runs continuously alongside, mostly making Docker and non-Docker layouts behave identically.
The stability test is new enough that its server selection and timeout handling are still being fixed, so expect the next releases to keep refining it rather than opening another surface. Docker and asset-layout parity looks like the other ongoing thread.

The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.
The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.
Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
