What reforms were enacted in the USSR after Stalin died

After Stalin died what all reforms were enacted by people like Beria or Khrushchev? My understanding is Beria:

Made torture illegal (which probably wasn’t listened to)
Wrote off the ‘doctor’s plot’ as a farce
released over a million political prisoners

While Khrushchev raised the rations of people in slave labor camps, I think up to 1200 calories a day or so. He also cut the gulag population from 13 million to 5 million.
