What is Fluent Bit?

Fluent Bit keeps two lines alive while the 5.x branch quietly opens 5.1.

Three release lines are visible at once. The 4.2 branch takes backported fixes — Stackdriver payload over-reads, Avro empty-map handling, Windows event-log enrichment. The 5.0 line carries the forward work. And a 5.1 line has appeared with two tags whose titles are raw commit messages about test changes, which is what this repository produces when a tag is cut off a routine commit rather than a prepared release.

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.

5.0

Fluent Bit keeps two lines alive while the 5.x branch quietly opens 5.1.

◆ Current state

Three release lines are visible at once. The 4.2 branch takes backported fixes — Stackdriver payload over-reads, Avro empty-map handling, Windows event-log enrichment. The 5.0 line carries the forward work. And a 5.1 line has appeared with two tags whose titles are raw commit messages about test changes, which is what this repository produces when a tag is cut off a routine commit rather than a prepared release.

◆ Where it's heading

The engineering emphasis on the maintained branches is memory safety and protocol correctness in the input and output plugins: use-after-free in in_forward, over-reads in out_stackdriver, endian-safe gzip magic reads, oauth2 token parsing hardening. That is the profile of a project whose failure mode is a crash in someone else's log pipeline, and it is being worked systematically rather than opportunistically.

◆ Prediction

Expect the 4.2 backport stream to continue at roughly monthly cadence and the 5.1 line to keep accumulating commit-titled tags until a prepared announcement release appears with real notes.

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.
