LXD 2.0.12 リリースのお知らせ

14th of August 2020

はじめに

LXD チームが LXD 2.0.12 のリリースをお知らせします!

このリリースは、2021 年 6 月までサポートされる LXD 2.0 に対する 12 個目のバグフィックスリリースです。

バグ修正と改良点

一番古い LTS リリースである LXD 2.0 は 2017 年 10 月以来リリースがありませんでした。

この 2.0 系の LTS ブランチはセキュリティフィックスのみが行われるモードに入っています。このリリースは 2.0.11 に入らなかった古いバグ修正のいくつかと、LXD のこのブランチをビルドできるようにするための修正のみを含んでいます。

この一部として、LXD の依存関係のいくつかが、古いバージョンの Go でビルドできなくなり、LXD 2.0.11 が Go 1.13, 1.14, 1.15 で実行でき、少なくとも 1.11 ではビルドできないことを確認しました。

重要な修正やセキュリティ上の修正はないため、古い Go のバージョンを必要とするディストリビューションは 2.0.11 を維持するべきです。

最後に、LXD 2.0 LTS をまだ使っているユーザーは、このブランチでは重要なセキュリティ上の問題のみが修正され、1 年以内にサポートが終了しますので、より新しいバージョンにアップグレードすることをおすすめします。2.0 LTS から直接 4.0 LTS へアップグレードすることがサポートされています。
