NBT tags require quotes when some characters are used
This command no longer works while it was never an issue before:
give @p diamond_sword 1 0 {ench:[{id:16,lvl:10},{id:19,lvl:5},{id:20,lvl:3},{id:21,lvl:5},{id:22,lvl:5},{id:34,lvl:5},{id:70,lvl:1},{id:71,lvl:1}],display:{Name:Aya's dream sword,Lore:["Carefull where you swing!"]}}
The screenshot shows it's breaking off on the ' character, this worked in previous snapshots, so I assume a bug.

You need quotes around strings with special characters or spaces, see MC-116410.

Duplicates MC-116410, you need quotes around your text because it contains a special character (space).

You require quotes as ' and space are not whitelisted characters anymore.
Confirmed.
One critical note though... If I had known this up front I wouldn't have wasted my time over it. Don't get me wrong: I appreciate Minecraft and what it provides, but it would help to mention these things in the official release notes instead of cryptic stuff.
Part of that was making unquotes strings only allow A-Za-z0-9._-+
