Same data pack format, same registries. That is the strongest safe-for-data-packs signal a diff can give, and it is still not proof — behaviour changes and bug fixes are invisible to it.

The official notes
Read the Minecraft 1.20 Pre-Release 4 article on minecraft.net. It lives at an earlier build's address: minecraft.net updated that article in place and retitled it for 1.20-pre4.
The article has no technical-changes section — it lists bug fixes only, or predates that heading.
