Runtime upgrades

What each upgrade touched

Files changed in each part of the subtensor code, per upgrade. Runtime, pallets, EVM and node change how the chain behaves; SDK, docs and tooling do not.

Files:01 to 910 to 3940 to 99100+

Every upgrade, newest first

The main changes are the release's own commit titles, with merges, version bumps and build fixes left out. The bar is chain code files changed.
