 ## Next
 
+* Added the MIT `LICENSE` file referenced by the CocoaPods specification.
+* Raised the minimum supported versions to iOS 15.0 and macOS 12.0 in CocoaPods and Swift Package Manager, matching the targets used to validate 3.6.0 with Xcode 27. Aligned the example app's target with iOS 15.0. Apps supporting older OS versions must stay on 3.6.0 or earlier.
+* Removed an unused session configuration binding and its compiler warning.
+
 ## 3.6.0
 
 * Added `Transloadit-Client` headers with the SDK name and version to assembly creation, status, and cancellation requests.

 ### CocoaPods publication
 
+Publication requires Kevin's approval after the release preparation PR is merged.

 Use a macOS machine with Xcode and CocoaPods installed. A pod owner must run
 `pod trunk register` with their pod-owner email address on that machine and
 confirm the session through the verification email. Run `pod trunk me` to
 confirm the session is verified and lists `Transloadit` before pushing.

-Publish with `pod trunk push Transloadit.podspec` when the Xcode toolchain supports
-the podspec's deployment targets.
-
-For 3.6.0, the plain push failed because Xcode 27 rejected the podspec's iOS 10.0
-and macOS 10.11 deployment targets. It also warned that the referenced `LICENSE`
-file is missing and that an existing `identifier` binding is unused. The
-successful push used a temporary build configuration with Xcode's supported
-deployment targets and allowed those existing warnings:
-
-```sh
-(
-  set -e
-  RELEASE_VALIDATION_DIR="$(mktemp -d -t transloaditkit-release)"
-  trap 'rm -f "$RELEASE_VALIDATION_DIR/validation.xcconfig"; rmdir "$RELEASE_VALIDATION_DIR"' EXIT
-  cat > "$RELEASE_VALIDATION_DIR/validation.xcconfig" <<'XCCONFIG'
-IPHONEOS_DEPLOYMENT_TARGET = 15.0
-MACOSX_DEPLOYMENT_TARGET = 12.0
-XCCONFIG
-  XCODE_XCCONFIG_FILE="$RELEASE_VALIDATION_DIR/validation.xcconfig" \
-    pod trunk push Transloadit.podspec --allow-warnings
-)
-```
-
-This override applies only to the validation build. The published podspec still
-comes from the release tag; build and import validation remain enabled.
-It validates iOS 15.0 and macOS 12.0, rather than the older deployment targets
-declared by the podspec.
-
 The 3.6.0 push returned GitHub commit API timeouts despite completing publication.
 Run `pod trunk info Transloadit` and confirm the version is absent before retrying
 an interrupted push.
