1.4.5 (dev)

Add --no-index flag to pip-compile to avoid emitting --index-url into the output (useful if you have configured a different index in your global ~/.pip/pip.conf, for example)
Fix: ignore stdlib backport packages, like argparse, when listing which packages will be installed/uninstalled (#286)

1.4.4

Fix: unintended change in behaviour where packages installed by pip-sync could accidentally get upgraded under certain conditions, even though the requirements.txt would dictate otherwise (see #290)

1.4.3

Fix: add --index-url and --extra-index-url options to pip-sync
Fix: always install using --upgrade flag when running pip-sync

1.4.2

Fix bug where umask was ignored when writing requirement files (#268)

1.4.1

Fix bug where successive invocations of pip-sync with editables kept uninstalling/installing them (fixes #270)

1.4.0

Add command line option -f / --find-links
Add command line option --no-index
Add command line alias -n (for --dry-run)
Fix a unicode issue

1.3.0

Support multiple requirement files to pip-compile
Support requirements from stdin for pip-compile
Support --output-file option on pip-compile, to redirect output to a file (or stdout)

1.2.0

Add CHANGELOG :)
Support pip-sync'ing editable requirements
Support extras properly (i.e. package[foo] syntax)

(Anything before 1.2.0 was not recorded.)
