Under a.m. URL I found WIN 18.104.22.168 together with LibO_3.6.0_Win_x86_install_multi.msi and 3.6.0 help.
I think those different versions should be in different folders (of course, I downloaded 3.6.0 together with 3.5 help files ...)
And what a strange 3.6.0 installer is that far away from all our name conventions?
This hodge podge seems to be WIN only.
Not a bug/worksforme.
The pre-release page is not for the general public, but for those who want to try out the build before it is distributed over the mirror network.
And as LO usually maintains two versions at a time, it is used for both.
i.e. if 3.5.x as well as 3.6.x will end up in there before being distributed to the mirrors.
However it is unusual to release two versions at the same time, so it is unlikely that there will be a confusion about the builds there.
But people tend to make mistakes, and sometimes forget to delete the old stuff before putting the new stuff out :-)
That the 3.6.0 ones were still on there was a mistake, they should have been removed after the build was available using the regular mirrors.
(It was windows-only, since windows builds were replaced just after the release, since the digital signature was missing)
