What is epiflows?

epiflows has shipped four releases in eight years, none of which changed the code.

epiflows predicts the spread of infectious disease along population flows between locations, and it is effectively dormant. The whole visible history spans 2018 to 2026 in four entries: the first CRAN release, a Zenodo archival tag, a Roxygen patch whose notes state the functionality is unchanged, and a 2026 release replacing deprecated ggplot2 and tibble calls. No entry describes new epidemiological capability.

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.

epiflows has shipped four releases in eight years, none of which changed the code.

◆ Current state

epiflows predicts the spread of infectious disease along population flows between locations, and it is effectively dormant. The whole visible history spans 2018 to 2026 in four entries: the first CRAN release, a Zenodo archival tag, a Roxygen patch whose notes state the functionality is unchanged, and a 2026 release replacing deprecated ggplot2 and tibble calls. No entry describes new epidemiological capability.

◆ Where it's heading

The package is being kept installable rather than developed. The one recent release is dependency maintenance contributed from outside, which is the pattern for RECON-era epidemiology packages that have outlived their original project funding. Two separate entries are both labelled version 0.2.1, so even the version history is not a reliable guide to what changed.

◆ Prediction

Any further releases will most likely be more deprecation cleanup to keep the package on CRAN; there is nothing in the record suggesting active development has resumed.

ANALYTICS
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.
