A side-by-side editorial comparison of Fluent Bit and ggcorrplot — 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.
ggcorrplot came back after four years and found its significance markers had been lying
ggcorrplot draws correlation matrices in ggplot2 with optional significance marking and hierarchical reordering. It sat untouched from late 2022 until mid-2026, then shipped 0.2.0 and 0.3.0 sixteen days apart. Between them they added the display options users had been requesting since 2016 and repaired a set of bugs where hc.order = TRUE silently changed which cells were marked significant.

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.

Both releases chase the same target: parity with the older corrplot package inside a ggplot2 object. Significance stars appended to coefficient labels, circle scaling, decimal control, then boxed cells and glyphs sized by absolute correlation — these are corrplot's visual vocabulary reimplemented where they can be composed with other ggplot2 layers. The bug fixes point the other way, at foundations: p-values matched to cells by name rather than row position, clustering computed on the unrounded matrix, tl.col actually applied.
With the corrplot look largely reproduced and the correctness backlog cleared, the remaining gap is the mixed upper/lower display corrplot supports; that is the natural next argument if the current release pace holds.
