You want conda update --all.
conda search --outdated will show outdated packages, and conda update --all will update them (note that the latter will not update you from Python 2 to Python 3, but the former will show Python as being outdated if you do use Python 2).
Before you proceed to conda update --all command, first update conda with conda update conda command if you haven't update it for a long time. It happent to me (Python 2.7.13 on Anaconda 64 bits).
the Conda Package Manager is almost ready for beta testing, but it will not be fully integrated until the release of Spyder 2.4 (https://github.com/spyder-ide/spyder/wiki/Roadmap). As soon as we have it ready for testing we will post something on the mailing list (https://groups.google.com/forum/#!forum/spyderlib). Be sure to subscribe
Cheers!

conda update allupdates only compatible version for my py27 environment?conda update --allwill only install packages that are compatible with one another, and it will not update you from Python 2 to Python 3.conda search --outdatedshows you all the available versions of each installed AND outdated package, that is a bit too much in many cases,,, Personally I prefer to useconda update --all, that shows what's going to be installed and prompts for confirmation: you replyNand you have a compact list of outdated packages.conda update --allalso differs fromconda search --outdatedin that it runs through the solver, meaning some packages that have newer versions may not be updated if other packages have dependency restrictions (or, for example,conda update --allwon't update from Python 2.7 to Python 3.4).conda. It answered many questions I had.
