-**Upgrading?** Read [MIGRATING.md](MIGRATING.md) *before* you bump the version. v0.13.0 breaks all six SDKs, and 61 of those breaks survive a clean build — 55 give no signal at all, and 6 compile and then fail at runtime on one particular shape of response, which is not the same shape in every SDK: Go's four need the field *absent*, Ruby's and Kotlin's need it *present*.
+**Upgrading?** Read [MIGRATING.md](MIGRATING.md) *before* you bump the version. v0.14.0 breaks all six SDKs: `ListUploadVersions` now returns version events instead of uploads — the four typed SDKs catch that at compile time, Ruby and Python just start seeing different keys — and every 507 now reports the new `limit_exceeded` code instead of a retryable `api_error`, which silently reroutes any error handling that branches on the old code. Coming from v0.12.0 or earlier? v0.13.0's section still applies, and 61 of its breaks survive a clean build.

The compiler catches the type changes — `ListVersions` elements became `UploadVersion`, and `UpdateUploadRequest.Description` became `*string` — but not the reroute: every 507 now reports `limit_exceeded` instead of a retryable `api_error`, so a `case` falling through to a default arm sends storage, project and webhook limits wherever that default goes.
