3.1.1

• The "peep had a problem" traceback is no longer output for several cases of pip installation errors that were not peep's fault: for instance, the specified package version or requirements file not existing.
• peep port now emits URLs for URL-based requirements, if you're using pip 6.1.0 or greater. (jotes)

Full changelog: 3.1...3.1.1

3.1

• Print the name each new requirements file we encounter during peep port. This helps untangle the mess if your files use includes. (pmac)
• Always put hashes on their own lines, even if there's only one. (pmac)

Full changelog: 3.0...3.1

3.0

• Add support for pip 8.x.
• Drop support for the --allow-external, --allow-unverified and --allow-all-external arguments (for compatibility with pip 8).
• Drop support for Python 3.1/3.2.

Full changelog: 2.5...3.0

2.5.0

• Support pip 7.x, through the currently latest 7.1.2, working around its buggy line counting. (kouk)
• Add peep port command to facilitate the transition to pip 8's hashing.
• Fix bug in which the right way to call parse_requirements() would not be autodetected.

Full changelog: 2.4.1...2.5

2.4.1

• Tolerate pip.__version__ being missing, which can apparently happen in arcane situations during error handling, obscuring informative tracebacks.
• Fix flake8 warnings again, and add flake8 to Travis runs.
