Why is that , are you talking the new version ? what changed exactly because I read the changelog and I honestly didn't understand much , too much technical stuff .
The new Bitcoin Core version (0.12.0) enables you to run a wallet in pruned mode. This means that you can use it without storing the whole blockchain. Essentially it can cut down the usage from around 60 GB of data to around ~2 GB. You only store the last X amount of blocks.
