 ## Unreleased
 
+- `apple upload` finds the IPA of a build made with `--out`: `apple build` notes its IPA and out folder in `.storebound/last-apple-build.json`, and upload searches `--out` (new flag), then that last build's out, then `apple.build.out` / `build/ios`. When nothing is found, the error names every folder it searched and the last build's IPA.
+
 ## 0.8.56 · 2026-10-27
 
 - Release type. `apple.releaseType: afterApproval | manual | scheduled` (+ `apple.earliestReleaseDate`): `apple listing` creates versions with it (MANUAL when unset, existing versions untouched) and `apple submit` / `resubmit` set it before submitting when it differs, the dry run showing old -> new. New `apple release --after-approval | --manual | --scheduled <ISO date> [--platform] [--version] [--first-release] --yes` changes it on a version App Review has not approved yet (clear refusal otherwise, with `--manual-release` as the way out); exit 7 when it already has that type; an update is an agent step, after-approval on the first version of an app is exit 3 OWNER_STEP. Pitfall 125.
