I suppose that you're aware that you can customize the search for specific version of BOINC manager in BOINC home page just with some switches
QuoteSpecialized download pages
Some sites may want versions of the BOINC download page that show only particular versions or platforms.
This can be done by adding parameters to the http://boinc.berkeley.edu/download_all.php URL.
dev=1
Show versions that are still under test
min_version=x
Show no versions earlier than x
max_version=x
Show no versions later than x
version=x
Show version x in details
platform=x
Show versions for platform x (win/winx64/mac/linux/linuxx64/linuxcompat)
type=x
Show only a specific type of installer (win_old/win_new/bare_core/sea/mac_advanced)
xml=1
Show results as XML (other options are ignored).
Version is used to show only one specific file and must be used with platform and type.
e.g.: http://boinc.berkeley.edu/download_all.php?min_version=6.12&dev=1&platform=winx64 (http://boinc.berkeley.edu/download_all.php?min_version=6.12&dev=1&platform=winx64)
will show you version 6.12 and up + development version too and only in x64 versions of previous search.
I should sometimes check BOINC's trac for my ticket regarding this custom string (http://boinc.berkeley.edu/trac/ticket/513) I've filled a few years ago. Some of the functionality did not work at all, something was against logic, something got repaired... found it. I'll later test it again.
But new versions show up in Notices.....
