v1.1.2 - Add support for Django 2.0 and 2.1

• Add support for Django 2.0 and 2.1.
• Handle latitude and longitudes with initial + sign (issue #70).
• Use .iterator() to save memory during export (PR #80).
• Fix validation error in admin for Frequency.exact_times (PR #86).

v1.1.1 - Read CSV with extra whitespace

• Strip whitespace after commas in CSV files with skipinitialspace (issue #64, PR #65 and #68).
• Discard empty lines in CSV files (issue #66, PR #67)

v1.1.0 - Add support for Django 1.10 and 1.11

• Add support for Django 1.10 and 1.11
• Drop support for Django 1.7 and earlier, and for South migrations. If you are using these, upgrade to 1.0.0 first, migrate your codebase to Django 1.8 and Django migrations, then update to 1.1.0.
• Move Python 2 / Python 3 and other compatibilty code to multigtfs/compat.py. Exclude this file from the make qa coverage report, unless the COVERAGE_COMPAT environment variable is set. Because the cross-environment code is now in this file, many lines will be uncovered in a particular environment, while other files should be 100% covered. This file is tested in the supported environments in TravisCI, and a combined coverage report is generated in Coveralls, where compat.py should be 100% covered.
• Add a dockerized environment for the explore example app, and run it under Django 1.11.
• Whitespace-only values in import files are treated as empty values (PR #56)

v1.0.0 - Django 1.7 - 1.9 support

• The project has been production-ready for a while. Updating the version
  number and the PyPI classifiers to reflect that.
• Add support for Django 1.7 through 1.9, and a compatibility layer to handle
  future versions.
• Add support for transitioning from South to Django migrations.
