In the docs (README.rst) we have:

Run migrations: python manage.py migrate aldryn_newsblog.

NOTE: aldryn_newsblog supports both South and Django 1.7 migrations. If using Django 1.7, you may need to add the following to your settings:

MIGRATION_MODULES = [
   …
   'aldryn_newsblog': 'aldryn_newsblog.south_migrations',
   # The following are for some of the depenencies.
   'djangocms_text_ckeditor': 'djangocms_text_ckeditor.migrations_django',
   'filer': 'filer.migrations_django',
   …
]

It should be something like this:

MIGRATION_MODULES = {
   …
   # The following are for some of the dependencies.
   'djangocms_text_ckeditor': 'djangocms_text_ckeditor.migrations_django',
   'filer': 'filer.migrations_django',
   …
}

• {} instead of []
• aldryn_newsblog in 'dev' branch uses django migrations by default;
• dependencies typo fix

checked with Django 1.7.7, django-cms 3.1.0rc1, newsblog 0.8.4

also 'sortedm2m', should be added to INSTALLED_APPS

filer also should be set up, at least

THUMBNAIL_PROCESSORS = (
    'easy_thumbnails.processors.colorspace',
    'easy_thumbnails.processors.autocrop',
    #'easy_thumbnails.processors.scale_and_crop',
    'filer.thumbnail_processors.scale_and_crop_with_subject_location',
    'easy_thumbnails.processors.filters',
)

sorry @mkoistinen I've forgot about that: python manage.py migrate aldryn_newsblog
I think it is prefer to do just python manage.py migrate because there is other apps with migrations.
