What is nuggets?

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

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.

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

◆ Current state

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

◆ Where it's heading

Two forces are shaping the package. One is coverage: baseline, complement and paired-baseline contrasts, correlations, tautologies, ancestors and clustering have all been added as first-class dig_ or explore_ surfaces, so the same search engine now answers a widening set of questions. The other is weight — Shiny packages moved from Imports to Suggests, BH and RcppThread dropped, XSIMD updated, parse_condition() rewritten in C++ — which keeps a package with an interactive app from forcing that app's dependencies on every user. Deprecations are handled through lifecycle rather than removed abruptly.

◆ Prediction

Expect the sparse-data optimisation to extend from crisp to fuzzy data, and explore() to keep gaining tabs as each new pattern family lands, on the roughly six-week cadence the 2.2 line has held.

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.
