Ok so this has a LOT, which I condensed as much as possible:
New songs:

• announcements.radio_tune
• customsongs.breakdancing_news
• customsongs.mcsdvictoryremix

New emotes : Ă - ă - Ć - ć -

New Items:

• Chaos Emerald (emerald custom model data 2 or something)
• Network Update/Telecast stuff (ink sacs with CustomModelData:1-40  for Characters and 500-510 for Images)
• New Hats!  Still sticks with CustomModelData:24-28 for Satellite Hat, Blue Headphones, Comic Mask, Mustache w/ Monocle, and Antenna
• Pride Flags!  Cookies with CustomModelData:2-20 or something, IDK there were a lot
  
  • Emotes are ≡±≥≤⌠⌡÷≈°∙ √ⁿ²■

I know this changelog seems short but believe me this is a LOT of content, primarily composed of Network Update sprites.
