What is OSQP?

QP solver that rebuilt its linear algebra layer for GPUs, then went quiet in beta.

OSQP is an operator-splitting quadratic program solver used widely as an embedded optimization backend. Its visible release history stops at the v1.0 beta from May 2023, which was a substantial rework: a pluggable linear algebra backend chosen at compile time, the separate cuOSQP GPU project folded into the main tree, and an Intel MKL backend added. That beta has not been followed by a stable v1.0 in this feed.

What is RESTEasy?

Jakarta REST implementation in pure maintenance across two parallel branches.

RESTEasy is the Jakarta RESTful Web Services implementation used by WildFly, and it ships every release twice — once on the 7.0.x line and once on 6.2.x, usually within an hour of each other. The overwhelming majority of each release note is Dependabot version bumps. Real fixes appear one or two per release and land on both branches: resource methods inherited from package-private classes not being registered, EJB interface methods not scanned for endpoint annotations, SSE response headers not committed when closing without sending.

0.0

QP solver that rebuilt its linear algebra layer for GPUs, then went quiet in beta.

◆ Current state

OSQP is an operator-splitting quadratic program solver used widely as an embedded optimization backend. Its visible release history stops at the v1.0 beta from May 2023, which was a substantial rework: a pluggable linear algebra backend chosen at compile time, the separate cuOSQP GPU project folded into the main tree, and an Intel MKL backend added. That beta has not been followed by a stable v1.0 in this feed.

◆ Where it's heading

The direction the beta set is clear — OSQP was becoming a solver core that could be retargeted at different compute hardware without changing the algorithm, with CUDA and MKL as the first two targets. Code generation and adjoint derivative computation moving into the C API point the same way, toward embedding OSQP inside other systems including differentiable pipelines.

◆ Prediction

The stable v1.0 is the obvious next milestone, but nothing in these entries indicates when or whether it landed — treat the backend rework as available only in beta form.

5.0

Jakarta REST implementation in pure maintenance across two parallel branches.

◆ Current state

RESTEasy is the Jakarta RESTful Web Services implementation used by WildFly, and it ships every release twice — once on the 7.0.x line and once on 6.2.x, usually within an hour of each other. The overwhelming majority of each release note is Dependabot version bumps. Real fixes appear one or two per release and land on both branches: resource methods inherited from package-private classes not being registered, EJB interface methods not scanned for endpoint annotations, SSE response headers not committed when closing without sending.

◆ Where it's heading

The project is tracking the Jakarta EE platform rather than pushing it — migrating to Jakarta Persistence 3.2, aligning @Inject handling with the CDI specification so resources no longer need a public no-arg constructor, and moving to JUnit 6 internally. There is no visible feature agenda beyond specification conformance and keeping the dependency tree current.

◆ Prediction

Expect the two-branch pattern to continue with the same fix backported to each; nothing in these entries indicates when 6.2.x support ends.
