What is Apache CloudStack?

CloudStack's feed shows two LTS branches maintained in parallel and little else

The visible activity on Apache CloudStack is branch maintenance across two long-term-support lines, 4.20 and 4.22. The newest tag, 4.20.3.1, carries no release notes at all — just a line stating it was tagged on a fixes branch. The most informative recent entry remains 4.22.0.1, a security release fixing seven CVEs, several of them access-control failures around backups.

What is logbin?

Relative-risk regression that converges where glm fails, under an unreadable tag order

logbin fits log-binomial models to estimate relative risk, a fit standard glm frequently fails to converge on because of the constrained parameter space. Its answer is a choice of algorithms — adaptive barrier, combinatorial EM, and expectation-maximisation on an overparameterised model — selected through a method argument and optionally accelerated with turboEM. The most recent release, in April 2025, replaces the variance-covariance calculation in summary.logbin so it matches summary.glm, and adds a testthat suite.

CloudStack's feed shows two LTS branches maintained in parallel and little else

◆ Current state

The visible activity on Apache CloudStack is branch maintenance across two long-term-support lines, 4.20 and 4.22. The newest tag, 4.20.3.1, carries no release notes at all — just a line stating it was tagged on a fixes branch. The most informative recent entry remains 4.22.0.1, a security release fixing seven CVEs, several of them access-control failures around backups.

◆ Where it's heading

This feed publishes tags, not changelogs: every maintenance release points at external documentation rather than listing what changed, so direction has to be inferred from version numbers and the occasional security advisory. What can be read from it is a steady dual-branch cadence, with 4.20 and 4.22 receiving parallel maintenance and 4.22 carrying the newer feature work. The one substantive disclosure in this window, the CVE batch, clustered around backup and template permissions.

◆ Prediction

The dual-branch maintenance pattern should continue, though the feed itself will not reveal feature direction unless a security advisory forces detail into it.

Relative-risk regression that converges where glm fails, under an unreadable tag order

◆ Current state

logbin fits log-binomial models to estimate relative risk, a fit standard glm frequently fails to converge on because of the constrained parameter space. Its answer is a choice of algorithms — adaptive barrier, combinatorial EM, and expectation-maximisation on an overparameterised model — selected through a method argument and optionally accelerated with turboEM. The most recent release, in April 2025, replaces the variance-covariance calculation in summary.logbin so it matches summary.glm, and adds a testthat suite.

◆ Where it's heading

The method work concluded in 2021 and the package has since been aligned with base R conventions rather than extended: the vcov calculation now mirrors glm's, and earlier releases added the contrasts, qr, R and effects components so standard glm S3 methods such as influence() and plot() work on logbin objects. Be warned that the feed's tag order is unusable — versions 2.0, 2.0.1, 2.0.2 and 2.0.4 were all pushed within ninety seconds on 23 July 2021 in non-monotonic order, while 2.0.3 carries a 2017 timestamp and restates 2.0.2's notes. Read the bodies, not the sequence.

◆ Prediction

Expect continued alignment with glm conventions and occasional CRAN maintenance; the algorithm set has been stable for four years and nothing in these entries suggests another is planned.
