Mastodon v2.8.0 がリリースされましたが、v2.7.4にgit merge v2.8.0するのはちょっとまってください。自動でマージすることができず、コンフリクトします。

更新の方法・注意点は、毎回リリースページに記載があります。こちらをよく読んで、更新を適用してください。 rubyのバージョンも上げる必要があるし、pullとかfetch&mergeするとハマるし、環境やデータベース壊したら元も子もないので、ちゃんと説明読んで作業を進めて下さいね。 https://github.com/tootsuite/mastodon/releases/tag/v2.8.0
ここでは、なぜマージできないのかもうちょっと知りたい人のために、その理由をざっくり説明します。

表示はずっと続きますが、tag: v2.7.1 のあたりでストップしておきます。
- 各行が、一つの更新に対応しています
- 更新の一つ一つは、「バージョン番号を2.7.1にする」とか「README.mdのコピーライト表記の年を2019にする」などのように、一つ一つの内容が明快になるような単位に分割されています
- ところどころ、
(tag: v2.7.1)などのような表記が挟まっています。これは、この更新の時点にv2.7.1という印（タグ）をつけたよ、ということです (HEAD)となっているものが、現在の位置です- 先頭の数字と英字の混じったもの
28866d329は更新を識別するIDです（コミットハッシュ）
ということで、v2.7.1から41個ほど更新して、そこにv2.7.2というタグがつけられています。そのあと9個の更新があってv2.7.3というタグが、11個の更新があってv2.7.4というタグがつけられていることがわかります。

うん、長いですね。すいません。v2.7.1の次についているタグがv2.8.0rc1になっています。積み上げられた更新の数も全然違いますね。
同じ内容だけど、違うIDの更新（commit）
注目してもらいたいのは、v2.7.1の直後からの更新内容とIDです。
内容は同じなのに、違うIDがついています。
これは何故かというと、v2.8.0を開発している最中に行った更新を、つまみ食いして、別の場所にコピーして持ってきているからです。
ひとつひとつの更新内容は基本的に同じですが、別の場所で作業していて、対象とするソースコードの状態も異なるので、違うIDがついた別物になっています。
stable-2.7ブランチ
別の場所には名前がついていて、stable-2.7と名付けられています。日本語で言うと「2.7の安定版」といった意味合いです。
開発中のバージョンが完成する前に、みんなに使ってもらっている前のバージョンにすぐに反映した方がいい修正がでてくることがあります。バグのヤバイやつとか、セキュリティ的にヤバイやつなどです。
こういう、新しいバージョンから、古いバージョンに一部を持ってくることをバックポート（逆輸入）と言います。
この時、v2.8.0に向かって更新を積み上げている本流（master）の流れを変えずに変更しなければいけないので、v2.7.1から別の方向に枝分かれ（ブランチ）させる必要がでてきます。そこで、これは2.7の安定版ですという意味でstable-2.7などの名前をつけて、分岐させるわけです。
ブランチの手動マージは、素人には難しい
分岐させてしまったので、v2.8.0とは似て非なるものになります。これを合流させることもできますが、同じ修正に別のIDがついているし、順番を飛ばして部分的に修正を入れてしまっているので、これを自動的に統合することは、もう難しくなっています。そこで、人間が手動で、ここはこっちの修正を採用するとか、間違って合成されてしまったものを直してあげなくてはいけなくなります。プログラムを理解できる開発者がやっても大変ですが、中身が理解できていないと、これは大変というより、無理というものです。
という事情により、枝分かれしたstable-2.7のv2.7.4から、元々のv2.8.0を開発していた本流に更新するのは、ちょっと大変過ぎて無理、ということになるワケです。
とかいって、実はそんなに大変でもない
実は、v2.8.0の方が先行していて、そこからバックポートしてきたという流れははっきりしているので、どちらを採用したらいいかは基本的にわかっているわけです。なので、自動でマージできなかった部分はv2.8.0の方を採用してしまえば大丈夫です。自動で追加する側を採用するという方法もあります。興味のある方は、ぜひ調べてみてください。
