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 phyloatlas?

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

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.

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

◆ Current state

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

◆ Where it's heading

The project's defining decision is that it archives the recipe rather than the corpus. Since 1.0.3 the Zenodo deposit holds metadata, provenance, and standardization code while the tree files live at their original sources, and the same principle was applied again when the TimeTree-of-Life was removed at the TimeTree project's request and reduced to a citation. What makes the correction log unusual is its direction: partitions keep getting reclassified from dated to undated as verification confirms the source papers described chronograms they never deposited. The atlas is being built to be honest about archival uncertainty rather than to maximize coverage.

◆ Prediction

The release cadence is driven by the manuscript review cycle, so expect corrections to continue until MEE acceptance and then slow sharply; the open thread most likely to produce the next one is the remaining recoverable archival uncertainty flagged across non-Condamine dated source trees.
