What is dbt Core?

dbt-core spent a day backporting one deprecation warning across eight EOL branches — the message is: upgrade.

dbt-core maintains an unusually wide set of live branches, and on August 14 it cut releases for 1.1 through 1.8 in a single day. Every one of them carries the same single feature: a warning when the user is running a deprecated dbt version. The older branches picked up a few long-standing backports alongside it — semver comparison, JSON log formatting, seeds from stored manifest data — and 1.4 through 1.6 dropped Python 3.8 testing now that it is end of life.

What is fossilsim?

A fossil-record simulator that quietly grew a trait-evolution engine.

FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.

dbt-core spent a day backporting one deprecation warning across eight EOL branches — the message is: upgrade.

◆ Current state

dbt-core maintains an unusually wide set of live branches, and on August 14 it cut releases for 1.1 through 1.8 in a single day. Every one of them carries the same single feature: a warning when the user is running a deprecated dbt version. The older branches picked up a few long-standing backports alongside it — semver comparison, JSON log formatting, seeds from stored manifest data — and 1.4 through 1.6 dropped Python 3.8 testing now that it is end of life.

◆ Where it's heading

This is a coordinated deprecation campaign rather than product work. Shipping the same warning to every ancient branch at once is how a maintainer starts reclaiming a support surface, and the parallel removal of Python 3.8 support points the same way. The actual development is happening on 1.11 and 1.12, where recent releases sync JSON schemas from dbt-fusion and fix adapter config recognition — the branch where the Fusion engine transition is visible.

◆ Prediction

Expect formal end-of-life announcements for the branches that just received the warning, and continued dbt-fusion schema convergence on 1.12. The backport waves should thin out once the deprecated branches are formally retired.

ANALYTICS
0.0

A fossil-record simulator that quietly grew a trait-evolution engine.

◆ Current state

FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.

◆ Where it's heading

The arc runs from sampling mechanics toward simulating what the organisms actually were. Version 2.2.0 taught the package to handle occurrence data for occurrence birth-death models; 2.3.0 then added trait simulation under Mk, BM and OU, which is a different kind of output than fossil ages. Since then the work has been maintenance and keeping the FossilSimShiny GUI in step, suggesting the authors consider the current model set feature-complete.

◆ Prediction

The pairing of the 2.3.3 release with a FossilSimShiny version bump points to the GUI, not the library, as where the next visible work lands. The entries do not show enough activity to predict a specific new model family.
