Anaconda Latest: packages in the latest release of Anaconda (currently 4.4), without versions. This can be used to update all (and only) the packages that are found in Anaconda to the latest available version, since (you may be surprised to learn) the command `conda update anaconda` will not do this for you (see explanation below).

Is this list up to date?
Because I mess up with my base environment and I want to uninstall all the packages that don't belong to anaconda base.

I have the same question as HLatte.

Thanks @dominikgehl for this solution. Almost did the job for me, but had to run sudo bash otherwise terminal prompted missing writing permissions when executing conda install --file anaconda_latest_pkgs_no_versions.txt. Also not all packages were updated, but most of them (80 out of 113).
