Changelog evidence

Entry correctly flags the breaking binning change in ggplot2 4.0.0 (CRAN 2025-09-11). The changelog shows no reversion or fix to boundary/nbin parametrization through 4.0.3 (2026-04-22)—the change is permanent and still active. Current CRAN is 4.0.3; window should extend to 4.0.9 to cover the entire active 4.0.x release series, capturing users on current patches.

  "description": "In ggplot2 4.0.0, all binning stats (including geom_histogram()/stat_bin()) switched to a boundary/center parametrisation rather than origin, and the default boundary is now chosen to better adhere to the nbin argument. This may silently change the bin edges and resulting bar positions/heights of histograms that rely on default binning, with no code change required.",
