Comment (by mojca):

 Once https://github.com/macports/macports-ports/pull/5457 gets merged we
 should address #58361, but probably going straight to 5.30 rather than to
 5.28 first.

 Changing individual ports is pretty straightforward: just change 5.26 or
 5.28 to 5.30. Ideally make sure if any port depends or is a dependent of
 that port (visit https://ports.macports.org/port/<name>). Sometimes
 several ports need to be updated at the same time. So ... after changing
 5.26 or 28 to 5.30 ... just check if the port still builds ok (for those
 of ports for which you care also check if they work fine) and open a pull
 request.

 Then again ... there are lots of ports, so one option is to simply keep
 replacing numbers and leaving it to CI infrastructure to test the builds.
 That's still much better than not doing any work at all.
