What is adjustedCurves?

A survival curve package spending release after release correcting its own estimates

adjustedCurves computes confounder-adjusted survival and cumulative incidence curves across a range of estimators - IPTW, AIPTW, Aalen-Johansen, direct standardisation - with support for multiple imputation and bootstrapping. The recent releases are dominated by corrections to numbers the package already reported. Version 0.11.4 fixed cumulative incidence estimates under method="aalen_johansen" that were being read one time step early, which the maintainer notes could differ substantially when events are few, and added risk and event counts to the ggsurvplot conversion including correctly pooled values under multiple imputation.

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.

A survival curve package spending release after release correcting its own estimates

◆ Current state

adjustedCurves computes confounder-adjusted survival and cumulative incidence curves across a range of estimators - IPTW, AIPTW, Aalen-Johansen, direct standardisation - with support for multiple imputation and bootstrapping. The recent releases are dominated by corrections to numbers the package already reported. Version 0.11.4 fixed cumulative incidence estimates under method="aalen_johansen" that were being read one time step early, which the maintainer notes could differ substantially when events are few, and added risk and event counts to the ggsurvplot conversion including correctly pooled values under multiple imputation.

◆ Where it's heading

Multiple imputation is the recurring fault line. The standard error pooling formula was implemented incorrectly until 0.11.2, then fixed again in 0.11.3 for the bootstrapping-plus-imputation combination, and 0.11.4 added the pooled risk table values that had previously been omitted entirely. A separate thread quietly removed capability: tmle and ostmle methods went in 0.10.0, and tmle support was pulled again in 0.11.1 after the concrete package left CRAN. Feature work does happen - risk tables, contrast arguments, the extend_to_last control on IPTW curves - but it is outweighed by correction.

◆ Prediction

Expect continued estimator-level corrections rather than new methods, and a possible return of tmle support if its upstream dependency returns to CRAN, since the removal was described as temporary.

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.
