26.3 Pre-Release 1 — release journal

What 26.3-pre-1 changed for data packs, measured against 26.3-snapshot-10, the build before it. Released 2026-09-01; development build — not a release.

⚠ Breaking for data packs

This build removed 2 registries. Any file that referenced them stops loading. number_provider looks renamed to context_int_provider (80% of its entries reappear there) — in those cases the fix is likely moving files, not rewriting them.
