In recent months, WotC has altered some of the text found in the original 5th Edition core rulebooks to accommodate D&D's ongoing move towards inclusivity. Many of these changes are reflected on D&D Beyond already--mainly small terminology alterations in descriptive text, rather than rules changes.
Teos Abadia (also known as Alphastream) has compiled a list of these changes. I've posted a very abbreviated, paraphrased version below, but please do check out his site for the full list and context.
- Savage foes changed to brutal, merciless, or ruthless.
- Barbarian hordes changed to invading hordes.
- References to civilized people and places removed.
- Madness or insanity removed or changed to other words like chaos.
- Usage of orcs as evil foes changed to other words like raiders.
- Terms like dim-witted and other synonyms of low intelligence raced with words like incurious.
- Language alterations surrounding gender.
- Fat removed or changed to big.
- Use of terms referring to slavery reduced or altered.
- Use of dark when referring to evil changed to words like vile or dangerous.
and if they announce it, it's endless chestbeating about how they are forcing changes on the fandom.
