macOS 15.3 freed up my storage space

I have a MacBook Air M1 2020 256gb. Before the update i always had about only 70-80gb free storage. I always maintained this free space by regularly clearing my cache and backup files. But now on the Sequoia 15.3, i have 131gb of free storage. I disabled Apple intelligence and Siri, that’s all what I did different. Did i lose any important system folders? Or has anyone observed the same increase in storage after the update? Thanks!
