This depends on your website, niche, keywords, competition, current backlink profile and other things. Most of the times it's best to keep doing what you've been doing so far, no matter what updates come out, cause actually Google makes updates to its algo everyday, and it would be impossible to follow all of them in your SEO process. IMO, it's not a spam game anymore, so build natural looking, good contextual backlinks for tier1 and you don't need to stress about google updates.
