はじめに

約40日ぶりのリリースになるかと思います。やはり新型コロナウイルス前に比べるとリリースされる間隔が長くなっています。

基本的にはおとなしい内容かと。引き続きCRS3xxび動作安定性の向上に力を入れている感じでしょうか。またIPQ4018/4019についてもVLAN使用時の安定性の向上なども入っているので、RB3011、RB4011は恩恵を受けそうです。

また未確認ではありますがパフォーマンスの一部に何を抱えているとの情報があった CCR2004-1G-12S+2XS ですが、搭載チップの98PX1012向けに改善を入れたらしく、パフォーマンスが改善している可能性があります。

フォーラムを見る限りではRB750Gｒ3で正しくhealthが表示されない、再起動に時間が掛かる、全体としてはDoH使用時にメモリリークを確認している、などが報告されています。
