EVE Online is on the cusp of releasing Retribution 1.1 on February 19th, and a meaty (is there any other kind from CCP?) blog post outlines three significant balance changes that will arrive with the patch.
The first change is reorganizing streamlining and reorganizing battlecruisers, particularly with former tier 1 and 2 ships in this category. Then the team is moving on to fix an imbalance among the practice of armor tanking, including adding a new skill and a set of new modules to help with deficiencies. Finally, black ops ship fixes are slated for 1.1; they'll soon have a greater range and lowering fuel costs.
As always, this is but a brief overview of the novel-length explanations that CCP provides, so if any of this is pertinent to you, be sure to read the post in detail.
