What is Apereo CAS?

CAS 8.0 is six release candidates deep with notes that describe nothing

Apereo CAS is working through a long v8.0.0 release-candidate series, reaching RC6 by late June 2026. The candidates are published with a fixed template — links to release notes, documentation, commit log and policies, plus contributor thanks — and no description of what each one changed, so the substance of the 8.0 cycle is not readable from the releases themselves. The one entry with real content is v7.3.7.1, a patch pointing at a published OIDC vulnerability advisory.

What is q2?

After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.

q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.

CAS 8.0 is six release candidates deep with notes that describe nothing

◆ Current state

Apereo CAS is working through a long v8.0.0 release-candidate series, reaching RC6 by late June 2026. The candidates are published with a fixed template — links to release notes, documentation, commit log and policies, plus contributor thanks — and no description of what each one changed, so the substance of the 8.0 cycle is not readable from the releases themselves. The one entry with real content is v7.3.7.1, a patch pointing at a published OIDC vulnerability advisory.

◆ Where it's heading

The observable pattern is a maintained v7 line receiving security patches while v8 advances through candidates at roughly monthly intervals with a small, stable set of contributors. Beyond that, the release notes are too thin to establish what 8.0 changes for operators, which matters for an identity product where upgrade planning depends on knowing exactly what moved.

◆ Prediction

Expect the RC series to continue at a monthly cadence toward an 8.0 release, and the v7 line to keep receiving security patches; what 8.0 actually delivers cannot be predicted from these entries.

6.3

After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.

◆ Current state

q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.

◆ Where it's heading

The light-dark epic is the shape of how this team retires a Quarto 1 feature: a design doc, then ThemeConfig growing a parsed dark variant, dual theme compilation with color-scheme emission, attributed stylesheet links, a color-mode toggle runtime, an accessibility-aware highlight-style reader, a brand light/dark seam, and an end-to-end verification pass against quarto-web before the docs land. One phase (D) was deferred with its options recorded rather than dropped. Around it, panel-tabset support lands, format.html.css is finally copied and rebased per page, and the llms companion output gains a link-format attribute so authors control where companion links point — the one thread tying this release back to the v0.22.0 work.

◆ Prediction

Expect the remaining Q1 parity items to keep setting the release agenda, with the deferred light-dark phase D and the freshly opened panel-tabset plan the two named strands most likely to fill the next few tags. npx distribution for the standalone Quarto Hub MCP bundle is still the only distribution item the notes explicitly call planned.
