Haven't Played Since Shadowkeep, What's Changed?

[THEOTHERJESTER]

I've been thinking about reinstalling D2, I haven't really played since Shadowkeep. Has anything major changed? I heard that some content was removed since then. Is that true?

Yes. Destiny Content Vault. Anything pre-Shadowkeep destinations and raids (except Last Wish,Dreaming city, Earth and Nessus) were vaulted. And most of those weapons were sunset but some were brought back after changing the perk pool for different seasons.
A new subclass - Stasis was introduced in Beyond Light expansion. Darkness based subclass. Stasis weapons as well. Beyond Light released with a new planet called Europa and a new raid called Deep Stone crypt.
Witch queen expansion brought a new place called Throne world (Savathun's throne world) which is above Mars and a new raid called Vow of the Disciple (A disciple of the darkness). A small portion of Mars is playable in the campaign and for crafting weapon building.
You can customize supers now with Void and Solar 3.0. Inspired by stasis subclass. Arc 3.0 next season.
This is just a short summary of the major events so far.
