-## Resubmission
-
-This is a resubmission. Compared to the previously submitted version (2.1.0):
-
-- I replaced the `\\dontrun{}` example for `extract_mfcc()` with a fast,
-  executable example. It creates a short WAV file under `tempdir()`, guards the
-  optional `tuneR` dependency with `requireNamespace()`, and removes the file
-  after use.
-- I unwrapped the short `phontrast()` and `hier_boot_jsd_model()` bootstrap
-  examples after measuring them below five seconds. I also reduced the
-  illustrative `estimate_jsd()` bootstrap count from 50 to 10, bringing that
-  example below five seconds so it could be unwrapped. No examples now use
-  `\\dontrun{}` or `\\donttest{}`.
-- I removed direct access to `.GlobalEnv` and `.Random.seed`. Seeded internal
-  sampling now uses a private deterministic generator, so `eval_seed` remains
-  reproducible without modifying the user's workspace or RNG stream.
-- Versions 2.2.0 and 2.3.0 added a multivariate-normal density backend and
-  distribution-aware plotting, respectively. Version 2.3.1 contains the CRAN
-  review fixes above; the previously published GitHub tags remain unchanged.
-
 ## Submission
 
-This is a new submission (first time on CRAN). `phontrast` is a rename and
-reframing of the previously GitHub-only package `phonJSD` (released through
-v1.2.0). Development, testing, and documentation were assisted by AI tools, as
-disclosed in the README; all design, analysis, and release decisions were made
-by the maintainer.
+This is an update to the CRAN release `phontrast` 2.3.1.
+
+Version 2.4.0 is being submitted three days after 2.3.1 because it corrects
+release metadata that users currently see: the GitHub 2.4.0 tag initially
+retained `Version: 2.3.1`, and the package citation remained frozen at version
+2.0.0. The tag, package version, NEWS, version-specific Zenodo DOI, and
+version-aware package citation are now consistent.
+
+## Changes
+
+- Added the opt-in proportion-standardized Pillai estimates documented in
+  `NEWS.md`; existing defaults and the original return fields are unchanged.
+- Corrected the package version metadata to 2.4.0.
+- Replaced the stale citation with a version-aware citation for Grant M. Berry
+  and the 2.4.0 Zenodo DOI <doi:10.5281/zenodo.21864533>.
+- Added tests that keep the installed citation version and DOI synchronized
+  with `DESCRIPTION`.
 
 ## Test environments
 
 - Local: macOS 26.5.2 (aarch64-apple-darwin23), R 4.6.1,
   `R CMD check --as-cran --no-manual`
+- GitHub Actions: Ubuntu latest, R release, `R CMD check`

-## Notes for the reviewer
+The unusually short interval is necessary to correct the public package
+version and citation metadata described above.
 
-* The spell-check flags domain terminology in the Description and
-  documentation (e.g. "Bhattacharyya", "Mahalanobis", "Pillai", "MFCCs",
-  "sociophonetics", "phonological"). These are standard terms from phonetics
-  and multivariate statistics; they are listed in `inst/WORDLIST`.
-* The `Description` cites Lin (1991) <doi:10.1109/18.61115> for the
-  Jensen-Shannon divergence.
-* `ggplot2`, `mgcv`, and `tuneR` are used only conditionally
-  (`requireNamespace()`), so they are in Suggests rather than Imports.
+The local PDF-manual check could not run because the local TeX installation is
+missing `inconsolata.sty`. All Rd checks, examples, tests, vignettes, and the
+HTML manual check completed successfully.
