Conda

-------------------
* faster algorithm for --alt-hint
* don't allow channel_alias with allow_other_channels: false if it is set in
the system .condarc
* don't show long "no packages found" error with update --all
* automatically add the Binstar token to urls when the binstar client is
installed and logged in
* carefully avoid showing the binstar token or writing it to a file
* be more careful in conda config about keys that are the wrong type
* don't expect directories starting with conda- to be commands
* no longer recommend to run conda init after pip installing conda. A pip
installed conda will now work without being initialized to create and
manage other environments
* the rm function on Windows now works around access denied errors
* fix channel urls now showing with conda list with show_channel_urls set to
true

-------------------
* fix removing packages that aren't in the channels any more
* Pretties output for --alt-hint

-------------------
* skip packages that can't be found with update --all
* add --use-local to search and remove
* allow --use-local to be used along with -c (--channels) and
--override-channels. --override-channels now requires either -c or
--use-local
* allow paths in has_prefix to be quoted, to allow for spaces in paths on
Windows
* retain Unix style path separators for prefixes in has_prefix on
Windows (if the placeholder path uses /, replace it with a path that uses
/, not \)
* fix bug in --use-local due to API changes in conda-build
* include user site directories in conda info -s
* make binary has_prefix replacement work with spaces after the prefix
* make binary has_prefix replacement replace multiple occurrences of the
placeholder in the same null-terminated string
* don't show packages from other platforms as installed or cached in conda
search
* be more careful about not warning about conda itself in pscheck
* Use a progress bar for the unsatisfiable packages hint generation
* Don't use TemporaryFile in try_write, as it is too slow when it fails
* Ignore InsecureRequestWarning when ssl_verify is False
* conda remove removes features tracked by removed packages in
track_features

-------------------
* add --use-index-cache to conda remove
* fix a bug where features (like mkl) would be selected incorrectly
* use concurrent.future.ThreadPool to fetch package metadata asynchronously
in Python 3.
* do the retries in rm_rf on every platform
* use a higher cutoff for package name misspellings
* allow changing default channels in "system" .condarc

-------------------
* add retries to download in fetch module
* improved error messages for missing packages
* more robust rm_rf on Windows
* print multiline help for subcommands correctly

-------------------
* correctly check if a package can be hard-linked if it isn't extracted yet
* change how the package plan is printed to better show what is new,
updated, and downgraded
* use suggest_normalized_version in the resolve module. Now versions like
1.0alpha that are not directly recognized by verlib's NormalizedVersion
are supported better
* conda run command, to run apps and commands from packages
* more complete --json API. Every conda command should fully support --json
output now.
* show the conda_build and requests versions in conda info
* include packages from setup.py develop in conda list (with use_pip)
* raise a warning instead of dying when the history file is invalid
* use urllib.quote on the proxy password
* make conda search --outdated --canonical work
* pin the Python version during conda init
* fix some metadata that is written for Python during conda init
* allow comments in a pinned file
* allow installing and updating menuinst on Windows
* allow conda create with both --file and listed packages
* better handling of some nonexistent packages
* fix command line flags in conda package
* fix a bug in the ftp adapter
