SpawnPoint

Here is a short list of some of the major improvements since Beta:

Massive performance increases (many players are reporting double frame rates, especially in Low Spec renderer)
New game maps, with more to come next week
New Bloodbath Training Ground with 4 bots and 3 other human players in a FFA (great for perfecting your skills before the challenge of taking on higher level opponents)
Changes to the Ranking system (Rank is now determined by your skill in battle not trials completed or time played)
Pre-made groups and pick-up groups are now separated in the Matchmaker queue
Lower ranked players (i.e. new players and beginners) receive an Offense and Defense bonus (making it more likely for them to hit their target)
Major improvements to the Database which improve loading times and mail/vendor response times during peak periods
Lots and lots of minor bug fixes, crash fixes and optimizations (with more still to come)
