昨年4月にリリースされたYocto3.1LTS(Dunfell)の12回目のポイントリリース、3.1.12 公開のアナウンスが
2021年12月1日付けでありました。

当初は11月26日リリース予定でしたが、11月15日版で構築されたものがQAを経てリリースされています。
前回のリリースは9月15日版でしたので、変更点は従来より多くなっています。

ポイントリリースは、基本的にCVEに登録された脆弱性対応のSecurity Fix 発見されたbugへの
対処が主となりますが、現時点(12/1 14:00JST)では、次回リリースに向けての修正のコミットは未登録と
なっています。
今回のリリースには、来年1月に実施が予定されているgithub.com のgit:// サポート停止に対する
対応が含まれています。

次のポイントリリース3.1.13は 2021/12/22 を予定しています。（間隔が短いですね……）
