IP address vectors for R that hit 1.0 and then went quiet.
ipaddress gives R first-class IPv4 and IPv6 vector types with the arithmetic, netmask and subnet operations that come with them, backed by C++. The 1.0.0 release in 2023 was the deliberate breaking cleanup: one result per input from the hostname functions, vectorised subnets(), several arguments forced to be named, and a country_networks() downloader added. Since then the only release has been a testthat deprecation fix.
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.

The package reached the interface it wanted and stopped. The five releases before 1.0.0 were almost entirely CRAN check compliance — deprecated C++ calls, HTML5 notes, a Windows toolchain change — with functional work confined to a couple of releases that shed heavy dependencies. That pattern, long compliance runs punctuated by rare interface work, is what the feed shows now.
On this cadence the next release is most likely another CRAN or upstream-testing compliance patch; nothing in the entries indicates new functionality in progress.

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.
