pmdarima 1.0.0 on Python PyPI

v1.0.0

Wheels will no longer be built for Python versions < 3.5. You may still be able to build
from source, but support for 2.x python versions will diminish in future versions.
Migrate namespace from 'pyramid-arima' to 'pmdarima'. This is due to the fact that
a growing web-framework (also named Pyramid) is causing namespace collisions when
both packages are installed on a machine. See Issue #34
for more detail.
Remove redundant Travis tests
Automate documentation build on Circle CI
Move lots of the build/test functionality into the Makefile for ease.
Warn for impending deprecation of various environment variable name changes. The following
will be completely switched over in version 1.2.0:
- 'PYRAMID_MPL_DEBUG' will become 'PMDARIMA_MPL_DEBUG'
- 'PYRAMID_MPL_BACKEND' will become 'PMDARIMA_MPL_BACKEND'
- 'PYRAMID_ARIMA_CACHE_WARN_SIZE' will become 'PMDARIMA_CACHE_WARN_SIZE'
