When is TeXLive's next release date? (and where is this information published?)

If you really can't wait any longer, simply install TeXLive2017 pretest!

I have written an blog article (in german ;-)) how to run a TeXLive mirror on a NAS in your LAN, but the basic steps are the same.

Download the distribution .e.g. with

rsync -av --delete --exclude="mactex*" ftp.cstug.cz::pub/tex/local/tlpretest /path/to/dir

or just the installer for a network installation and then run the relevant installer for your OS, e.g.:

install-tl-windows -repository http://<NAS-IP>/tlpretest -gui wizard or

install-tl-windows -repository http://<TL2017pretest-URL> -gui wizard or

install-tl-windows -repository /path/to/dir -gui wizard

Wait for a while or even a bit longer! ;-)

There won't be any changes, so this pretest version will be the official release version of TeXLive 2017!

As soon as TL2017 is officially released simply change the default repository back to its default or a server of your preference:

tlmgr option repository http://mirror.ctan.org/systems/texlive/tlnet

No need to wait for the official release! ;-)

TeX Live 2017 was released today. Enjoy.
