Android 4.3 (JELLY_BEAN_MR2) が出て結構時間がたちました、恒例のsignatureがらみのPermission比較やらなきゃーと思って放置してたら4.4(Kitkat)が出ちゃったので慌てて更新します。
前回までのPermission比較は

にあります。

何調べてるの？

本記事は署名関係の Android Permission に注目してバージョン間の差分を比較しています。
これらの Permission が要求されるAPIに関してはOSビルド時の署名が必要になります。

メーカー端末であれば販売メーカーに依頼を出して署名をしてもらう必要がありますが、

通常出来ません。
よって3rdパーティアプリを作成する場合これらの Permission を要求されるAPIは使用不可能になります。
Androidはバージョンアップを重ねる毎にこれら Permission の締め付けがきつくなってるのでバージョンアップ毎にチェックしています。
