• Fixed duplicated --trusted-host, --extra-index-url and --index-url in the generated requirements.

28 Mar 2017

• Regression fix: editable reqs were losing their dependencies after first round (#476) Thanks @mattlong
• Remove duplicate index urls in generated requirements.txt (#468) Thanks @majuscule

22 Mar 2017

• Recalculate secondary dependencies between rounds (#378)
• Calculated dependencies could be left with wrong candidates when toplevel requirements happen to be also pinned in sub-dependencies (#450)
• Fix duplicate entries that could happen in generated requirements.txt (#427)
• Gracefully report invalid pip version (#457)
• Fix capitalization in the generated requirements.txt, packages will always be lowercased (#452)

17 Nov 2016

• Adds support for upgrading individual packages with a new option --upgrade-package. To upgrade a specific package to the latest or a specific version use --upgrade-package <pkg>. To upgrade all packages, you can still use pip-compile --upgrade. (#409)
• Adds support for pinning dependencies even further by including the hashes found on PyPI at compilation time, which will be re-checked when dependencies are installed at installation time. This adds protection against packages that are tampered with. (#383)
• Improve support for extras, like hypothesis[django]
• Drop support for pip < 8

20 Oct 2016

• Add --allow-unsafe option (#377)

06 Jul 2016

• Add compatibility with pip >= 8.1.2 (#374) Thanks so much, @jmbowman!

11 May 2016

• Add warning that pip >= 8.1.2 is not supported until 1.7.x is out

03 May 2016

• Incorporate fix for atomic file saving behaviour on the Windows platform (see #351)

02 May 2016

• PyPI won't let me upload 1.6.2

02 May 2016

• Respect pip configuration from pip.{ini,conf}
• Fixes for atomic-saving of output files on Windows (see #351)

06 Apr 2016

Minor changes:

• pip-sync now supports being invoked from within and outside an activated virtualenv (see #317)
• pip-compile: support -U as a shorthand for --upgrade
• pip-compile: support pip's --no-binary and --binary-only flags

Fixes:

• Change header format of output files to mention all input files

05 Feb 2016

Major change:

• pip-compile will by default try to fulfill package specs by looking at a previously compiled output file first, before checking PyPI. This means pip-compile will only update the requirements.txt when it absolutely has to. To get the old behaviour (picking the latest version of all packages from PyPI), use the new --upgrade option.

Minor changes:

• Bugfix where pip-compile would lose "via" info when on pip 8 (see #313)
• Ensure cache dir exists (see #315)

23 Jan 2016

• Add support for pip >= 8
• Drop support for pip < 7
• Fix bug where pip-sync fails to uninstall packages if you're using the --no-index (or other) flags

20 Jan 2016

• 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)
• Fix pip-sync failed uninstalling packages when using --find-links (#298)
• Explicitly error when pip-tools is used with pip 8.0+ (for now)

11 Jan 2016

• 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)

06 Jan 2016

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

13 Dec 2015

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

13 Dec 2015

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

13 Dec 2015

• 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

08 Dec 2015

• 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)

30 Nov 2015

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

(Anything before 1.2.0 was not recorded.)
