What is Cobbler?

A backport branch kept alive for downstreams, with the main line nowhere in sight.

Every release in Cobbler's visible history describes itself the same way: backports from main to make Cobbler more stable for the community. The 3.3.x line has absorbed real work under that framing — collection indices, lazy loading, new XML-RPC endpoints — but none of it originates here. The most recent item is a 3.2.3 build carrying the CVE-2024-47533 fix to an older branch, with its Fixed and Added sections left as literal TBD placeholders.

What is JointFPM?

Recurrent-event modelling settles, with mean_no() promoted to stable.

JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.

A backport branch kept alive for downstreams, with the main line nowhere in sight.

◆ Current state

Every release in Cobbler's visible history describes itself the same way: backports from main to make Cobbler more stable for the community. The 3.3.x line has absorbed real work under that framing — collection indices, lazy loading, new XML-RPC endpoints — but none of it originates here. The most recent item is a 3.2.3 build carrying the CVE-2024-47533 fix to an older branch, with its Fixed and Added sections left as literal TBD placeholders.

◆ Where it's heading

This is a stabilization branch serving downstream packagers rather than a product advancing on its own. The work that does land splits cleanly into three buckets: distribution coverage (Ubuntu 22.04, Debian 12, AlmaLinux, RHEL9, openSUSE and SLE signatures), API surface for integrators, and security backports. 3.3.3 flagged dump_vars as the replacement for get_blended_data as of 3.4.0 — a version that has not appeared in any release since.

◆ Prediction

Expect continued single-purpose backports to 3.3.x and older branches as CVEs surface; the entries give no indication of when or whether the 3.4.0 work these releases keep deferring to will ship.

0.0

Recurrent-event modelling settles, with mean_no() promoted to stable.

◆ Current state

JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.

◆ Where it's heading

The arc runs from a working estimator toward a usable one: input validation and error messages first, then control over the numerical integration, then a summary method and pass-through arguments to the underlying rstpm2 fit. The latest release adds no code so much as a stability commitment to a function users were already calling.

◆ Prediction

With mean_no() stable, the next work most likely targets the prediction and standardization paths rather than the model fit itself.
