A side-by-side editorial comparison of Fluent Bit and RadialMR — release velocity, themes, recent moves, and the top alternatives to consider.
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.
RadialMR's 2026 release corrects degrees of freedom that had been wrong since documentation.
RadialMR implements radial-plot formulations of IVW and MR-Egger Mendelian randomization, with outlier detection and interactive plotting. The recent history is thin on features and increasingly focused on the arithmetic: 1.2.4 in July 2026 fixes the degrees of freedom returned by egger_radial() to the documented n-2, corrects the heterogeneity p-value that inherited the same error, and repairs a negated lower bound in the random-effects bootstrap standard error search interval in ivw_radial().

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.
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.
RadialMR implements radial-plot formulations of IVW and MR-Egger Mendelian randomization, with outlier detection and interactive plotting. The recent history is thin on features and increasingly focused on the arithmetic: 1.2.4 in July 2026 fixes the degrees of freedom returned by egger_radial() to the documented n-2, corrects the heterogeneity p-value that inherited the same error, and repairs a negated lower bound in the random-effects bootstrap standard error search interval in ivw_radial().
This is a package being read closely by its maintainer rather than extended. The 1.2.x line pairs statistical corrections with defensive hardening — an rmr_format class check so unformatted input fails with a clear message, and plotly_radial() dispatching on object class instead of counting list elements. Both are the kind of change made while auditing, not while building.
Expect the audit to continue into the remaining estimator internals and print methods rather than new radial variants; the entries show no feature work queued.
