What is Apache CloudStack?

CloudStack ships two LTS branches in lockstep and publishes nothing but pointers

Apache CloudStack maintains 4.20 and 4.22 as parallel LTS lines and tags them together — 4.20.3.1 and 4.22.1.1 were cut 49 minutes apart, both with bodies that say only which branch was tagged. The release entries themselves carry no content: the standard body is a set of links to release notes, install, upgrade, admin, and API docs hosted elsewhere. The one exception is the security releases, where the CVE list is written inline.

What is stRoke?

Split itself in two, keeping the stroke-trial functions and exporting the rest

stRoke is now deliberately narrow: functions for handling clinical stroke trial data, mostly questionnaire scoring such as pase_calc() for PASE and mfi_calc() for MFI domain scores. It reached that state by subtraction — the 24.10.1 release moved eight general-purpose helpers out to a separate package, project.aid, and stated the change of focus in the notes. The most recent release, 25.9.1, is an eighty-character note about accommodating upcoming ggplot2 changes.

CloudStack ships two LTS branches in lockstep and publishes nothing but pointers

◆ Current state

Apache CloudStack maintains 4.20 and 4.22 as parallel LTS lines and tags them together — 4.20.3.1 and 4.22.1.1 were cut 49 minutes apart, both with bodies that say only which branch was tagged. The release entries themselves carry no content: the standard body is a set of links to release notes, install, upgrade, admin, and API docs hosted elsewhere. The one exception is the security releases, where the CVE list is written inline.

◆ Where it's heading

The pattern is stable and unlikely to change: maintenance releases on both LTS lines, a regular release on its own cadence, and security fixes backported across every supported branch at once. Because the feed only becomes descriptive when an advisory forces detail into it, the visible record of this project skews heavily toward vulnerabilities — seven CVEs across backups, templates, and cross-tenant Proxmox access in May alone — and says almost nothing about features.

◆ Prediction

Expect the paired-branch tagging to continue, with the next informative entry being a security release rather than a feature one. Nothing in this feed supports a claim about where CloudStack's capabilities are heading; that information lives in the release notes it links to.

Split itself in two, keeping the stroke-trial functions and exporting the rest

◆ Current state

stRoke is now deliberately narrow: functions for handling clinical stroke trial data, mostly questionnaire scoring such as pase_calc() for PASE and mfi_calc() for MFI domain scores. It reached that state by subtraction — the 24.10.1 release moved eight general-purpose helpers out to a separate package, project.aid, and stated the change of focus in the notes. The most recent release, 25.9.1, is an eighty-character note about accommodating upcoming ggplot2 changes.

◆ Where it's heading

The package uses calendar versioning and its history is one of scope being repeatedly redrawn: ds2dd() went to REDCapCAST in 2023, then the general data and project management helpers went to project.aid in 2024. What remains is domain-specific and slow-moving, and the past eleven months produced a single compatibility release. The maintainer's visible effort has moved to the sibling packages.

◆ Prediction

Expect further questionnaire scoring functions if the maintainer's own trials need them and compatibility releases otherwise; on the pattern set in 24.10.1, more of the remaining general-purpose functions could still migrate to project.aid.
