 djangocms-blog version together with cmsplugin-filer upgrade, you can just apply the migrations::
 
-    pip install cmsplugin-filer==1.1.1 django-filer==1.2.2 djangocms-blog==0.8.4
+    pip install cmsplugin-filer==1.1.3 django-filer==1.2.7 djangocms-blog==0.8.4

 .. note:: de-apply migration **before** upgrading cmsplugin-filer. If running before upgrade, the

           to migrate ``ThumbnailOption`` from cmsplugin-filer to filer
