What is Ory Hydra?

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

What is projoint?

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

◆ Current state

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

◆ Where it's heading

The through-line is reducing per-request database work in the hot authorization path — first by relocating flow state into encrypted client-side material, then by parallelizing JSON web key set generation and adding scope-claim strategies. Running underneath is tighter coupling to the rest of the Ory stack: the Kratos admin URL config and session-termination hook make Hydra less of a standalone component and more of one piece of an integrated identity suite. The verifiable-credentials work is the one thread pointing somewhere genuinely new, and it shipped against a draft specification.

◆ Prediction

The candidate series points toward a v2.2.0 general release consolidating the AEAD flow change and the credential-issuance work. The feed's silence after February 2024 gives no basis for judging when, or whether the draft-stage VC support advanced.

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

◆ Current state

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

◆ Where it's heading

The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.

◆ Prediction

Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.
