Many Supports now have multiple tiers as you progress through the game, providing different stat values, additional stats, or perhaps working a bit different to their lower-tier counterparts. Due to these changes, many existing support gems (which will now be tier 1 for cases where multiple tiers now exist) have received small numerical balance changes, and the effects of some support gems have been combined into a single gem.
