Where do these numbers come from?
Every count on this page is derived from the committed dataset diff between the two versions — nothing here is a summary of the patch notes.
Checked against Palworld v1.0.3 · verified 2026-08-25 · Data status
Between Palworld v0.7.0 and v1.0.3, 807 published build verdicts changed: 172 became legacy-only and 635 became newly obtainable, affecting 299 Pals. Every number here is derived from the committed dataset diff between the two versions, not from reading the patch notes.
The numbers above are this site's own reading of the datasets, not a recap of the patch notes. The image below is Pocketpair's own announcement art for the release, and it is here to say plainly which update the counts belong to — nothing on this page is sourced from it.

This compares one exact build across two versions. It does not plan a breeding session and does not calculate odds.
Both versions are evaluated with the same engine, and a build counts as changed only when its verdict changes. Counts here are derived from the committed datasets, so anyone with the repo can re-derive them. Rows we cannot classify from the data alone are counted as "under review" rather than assumed harmless.

The build was obtainable in the earlier version and, after the update, no current route reaches it — it can now only exist on a Pal that already has it.
