+
+v2.4 field--v2.5 field
+adcampaign_groups--campaigns
+adcampaigngroupsbylabels--campaignsbylabels
+adcampaigns--adsets
+adcampaignsbylabels--adsetsbylabels

+campaign_group_id--campaign_id
+
+
+The whole complete list is located here:
+https://developers.facebook.com/docs/marketing-api/reference/v2.5_rename/v2.6
+Again, in thos commit not all the phrases were changed.
+
+Also, after calling 
+Zuck.graph = (token, secret)
+it is NECESSARY to specify which api version is called by koala as fallowing:
+Koala.config.api_version = "v2.6"
+Otherwise, the error is raised.
