Hi all,

I’d like to share **sde-deltas** , an unofficial open repo that tracks what changes in the SDE from one build to the next, down to field level.

## What you get

For every new SDE build, the repo publishes what was added, removed or changed compared with the previous build, so you can update your own data incrementally instead of re-importing the whole SDE.

- `deltas/index.json`: build chain with dates and verification status
- `deltas/<build>/delta.jsonl.gz`: schema operations and record changes (added / removed / changed)
- `deltas/<build>/manifest.json`: per-table counts and SHA-256 hashes
- `summary.csv` / `verification.csv`: human-readable overview and discrepancies

## How it works

A GitHub Actions workflow fetches new builds, compares every table, and cross-checks the result against CCP’s official changelogs. It also flags changes that were _not_ documented in the changelog.

## How to consume it

1. Read `index.json` to find the builds you need
2. Download the deltas and verify their hashes
3. Apply the lines in order to your SDE copy
4. Optionally check record counts against the manifest

The first published delta is build 3031812.
