==========================
Using default repositories
==========================

When you use a conda command that involves looking for a package to install or
upgrade, by default conda searches the default repository located at
https://repo.continuum.io/pkgs. 

Main channel
============

https://repo.continuum.io/pkgs/main

Added Sept 26, 2017 with the release of Anaconda 5.0 and conda 4.3.27, the main
channel includes packages built by Anaconda, Inc. with the new compiler stack.
The majority of all new Anaconda, Inc. package builds are hosted here. This is
the top priority channel in conda's default channel list.

Free channel
============

https://repo.continuum.io/pkgs/free

The ``free`` channel contains packages built without the new compiler stack. It
includes packages built as far back as Fall 2012. The majority of these
packages are compatible with the packages in /main. These are included in
conda's default channels.

R Language channel
==================

https://repo.continuum.io/pkgs/r

Mirror: https://anaconda.org/r

Microsoft R Open conda packages and Anaconda, Inc.'s R conda packages. This
channel is included in conda's "defaults" channel. When creating new
environments, MRO is now chosen as the default R implementation.

MRO channel
===========

https://repo.continuum.io/pkgs/mro

Mirror: https://anaconda.org/mro

As of Dec. 19, 2017, this is an empty channel. Packages in this channel have
been moved to pkgs/mro-archive. New MRO packages are in the pkgs/r channel.

Pro channel
===========

https://repo.continuum.io/pkgs/pro

Now deprecated, though still available in conda's default channels. Packages in
this channel were once sold commercially, but are now open source and
available without charge. The last package was updated Feb. 2017. Includes
MKL Optimizations, IOPro and Accelerate.

Anaconda-Extras channel
=======================

https://anaconda.org/anaconda-extras

This channel contains packages custom built for customers by Anaconda, Inc.

Archive channel
===============

https://repo.continuum.io/pkgs/archive

Sometimes a package that is released
onto one of the other channels has an issue that forces Anaconda, Inc. to
remove it from the channel. In these cases, the package is archived to this
channel for anyone who still needs it.

MSYS2 channel
=============

https://repo.continuum.io/pkgs/msys2

Mirror: https://anaconda.org/msys2

Windows only - included in conda's default channels. Necessary for
Anaconda, Inc.'s R conda packages and some others in /main and /free. It
provides a bash shell, Autotools, revision control systems and the like
for building native Windows applications using MinGW-w64 toolchains.

Anaconda channel on anaconda.org
================================

https://anaconda.org/anaconda

The Anaconda channel on anaconda.org is a mirror of the packages available in
https://repo.continuum.io/pkgs/main, https://repo.continuum.io/pkgs/free,
and https://repo.continuum.io/pkgs/pro.
