In a lot of ways not much. No zoning for mulit unit lots so population probably has stayed about the same. The area around has become a lot more developed with a biotech boom. There used to be a forest across the street and now it’s been turned into a whole foods and business park. The college town nearby has exploded and taken over every square inch in apartments. You can walk around town though and it looks mostly the same but hippies and college professors have been replaced by yuppy tech bro families that like their gardens much more manicured instead of lush and wild.
