As of today (2025 Fri May 23), it appears:
I haven't looked into why /releases is out of date but think it should be updated.
context: I am resolving peer dependency warnings related to react 19 upgrade and went to /releases only to see that the version I had (3.16.1) was seemingly the latest. Only after looking at commits did I see that others were available.
p.s. Thank you for react-modal!
