What’s new for 2023?

• New-and-improved lectures (hopefully!), without masks! 😊
• Lectures are now supplemented by weekly “sections,” optional videos that review the week’s material in more detail!
• Dark mode for code in lectures!
• New problems in Problem Set 2 and Problem Set 4 and two updated labs!
• Many new practice problems in most weeks!
• A new-and-improved gradebook at cs50.me!

All this and more!
