Why did 1.19.2 -> 1.18.2? o_o
Odd numbered versions (1.17, 1.19, etc) are development/beta versions which get new features and content but may break things between releases. Even numbered versions (1.16, 1.18, etc) are stable releases which will mostly just be translation updates, bug fixes, etc. 1.17 was worked on for a couple years and eventually released as 1.18. 1.19 will also likely be worked on for a couple years and will eventually become 1.20. And so on.
