I have access to this machine now.
In the Python spirit of "it is easier to ask forgiveness than it is to ask permission", I took the liberty of removing all pending releases, because they seemed unneeded: https://dist.plone.org/release/
For example, there was a 4.3.13-pending which will never get turned into an actual 4.3.13: for some reason we skipped ahead to 4.3.14. Anyone who was brave enough to use 4.3.13-pending in production, very likely switched to 4.3.14 years ago.
Also, some symbolic pending links were broken.
What I do wonder, is if
5.2-pending should have remained. Is anyone using those? It could be useful to have a package or project tested against 5.2-pending, if that means that currently it points to 5.2.1, and once we have a real 5.2.2-pending, it would point to that. But that is almost the same as 5.2-latest, and would only differ for a few days a year.
Anyway, here is the list of pending releases that I have removed. Actually I have moved them to my home folder, so I can put them back. If anyone actually needs them, just ask.
