Unique coming to just mean unusual.

Ending sentences with propositions, and getting them jumbled around. My work does it in their advertisements and i cry every time.

"See what classes you can register for." Or modifying it to be worse; "see what classes you can register for fast"

Ain't ain't a word.

It is now.

Not exactly what you're asking, but double spaces after ends of sentences.

Pour one out for the Oxford Comma .

Let's eat Grandma

Commas save lives!

Apple put the nail in the coffin for adverbs when "Think different" let illiterates think they were speaking correctly.

The one that bothers me most (heard a lot in the software dev world) is when people say process-eez instead of processes, even if it is technically a word now, like ain’t

Australian English language is now largely Americanised, a process that started in the post-war era is now mostly complete.

• Terms such as 'gaol' have been widely replaced by 'jail'.
• 'Programme' is mostly replaced by 'program'.
• A 'car bonnet' is likely to be called a 'hood'.
• 'Play lunch' is mostly replaced with 'recess'.
• 'Pusher' is mostly called a 'pram'
• 'Lacker band' is now mostly just 'rubber band'.
• 'Boomer' no longer means kangaroo, but instead 'Old person.'

I'm not really bothered by it or anything, but it's been interesting to see it shift even over my lifetime.

I was one of the first years to have the new spelling rules.
It used to be, that a letter appearing more than twice in direct sequence would be cut to just twice. But that was lifted and is now just how many it should normally be. Examples: Schifffahrt, Brennnessel, Seeelefant.

It used to be, that "dass" could also be spelt "daß", but the rules for "ss" and "ß" were made clearer and more concise.

They also changed the way words could be split at the end of a line. If there was a double consonant in-between the syllables that were to split, the first syllable would take both consonants but now they are split evenly.
immer is split im-mer and not imm-er
But ck makes an exception: knackig is kna-ckig instead of old knak-kig

“Decimating” no longer means killing ten percent as the Romans did; now it is used to mean the killing of a majority, so it’s close to the opposite of its original meaning.

We were always supposed to put punctuation inside quotation marks; however, now it seems to be the user's choice of inside or outside. And I have to admit that most of the time when I’m using quotes, it seems more logical to me to place the punctuation outside of them.

"Reticent" used to mean 'reluctance to speak', or, 'holding your tongue', but in the last decade I saw it being used more frequently as a straight up synonym for 'reluctance'. I wonder if people maybe think it's a more authoritative sounding word?

It's not a change of convenience or cultural drift, just a sign of people reading less and subconsciously trying to hide it, I think.

From my perspective, literally being used for emphasis does not actually change its meaning, it’s simply hyperbole.

If you complain that you’ve been “waiting for hours”, even though it’s been 45 minutes, that doesn’t change the meaning of “hours”, you’re just exaggerating.

Hyperbole is a stylistic element; style is a completely different level of language than grammar/spelling/semantics (word meanings). As another example of style, ending a sentence with a preposition is grammatically correct but stylistically not recommended.
