What is campsismod?

The model layer under Campsis, renamed in step with it and increasingly JSON-addressable.

Campsismod holds the model object layer for the Campsis pharmacometric simulation suite: reading, editing and writing model definitions that Campsis then simulates. Its recent releases track a single programme, adding a JSON route into model objects and then renaming the whole API to snake_case in 1.4.0, a week before Campsis 1.9.0 did the same. Release notes are terse issue lists, so the reasoning behind each change has to be read from the sibling package.

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.

The model layer under Campsis, renamed in step with it and increasingly JSON-addressable.

◆ Current state

Campsismod holds the model object layer for the Campsis pharmacometric simulation suite: reading, editing and writing model definitions that Campsis then simulates. Its recent releases track a single programme, adding a JSON route into model objects and then renaming the whole API to snake_case in 1.4.0, a week before Campsis 1.9.0 did the same. Release notes are terse issue lists, so the reasoning behind each change has to be read from the sibling package.

◆ Where it's heading

This package moves when Campsis needs it to move. The JSON constructor landed here in 1.3.0 and reached Campsis datasets a day later; parameter uncertainty generation was handed down from Campsis in that package's 1.6.0; and the snake_case migration started here before propagating up. That ordering makes Campsismod the place where suite-wide interface decisions are taken first, even though the visible payoff shows up in Campsis.

◆ Prediction

Expect Campsismod to keep absorbing model-level responsibilities that Campsis currently handles, and to extend the JSON mapping to whatever parts of the model object it does not yet cover. The entries give no signal on a 2.0, and with the rename already spent there is little reason to expect one soon.

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.
