It's still a good option to wait for the next release.
Aside form the newest game engine inplemented and the new content it's also questionable to update mid-campaign.
For my part, every time I updated during a running campaign (allready 12 months in and further) every new patch applied messes around with the mission spawning.
The moment the new month starts (and missions get sheduled) I encounter alot of old missions that stopped spawning.
Those easy missions are free xp and loot so kinda 'cheating' in some way.
