+
+The rustup team is happy to announce the release of rustup version 1.27.0.
+[Rustup][install] is the recommended tool to install [Rust][rust], a programming language that is empowering everyone to build reliable and efficient software.
+
+If you have a previous version of rustup installed, getting rustup 1.27.0 is as easy as stopping any programs which may be using Rustup (e.g. closing your IDE) and running:
+
+```console
+$ rustup self update
+```
+
+Rustup will also automatically update itself at the end of a normal toolchain update:
+
+```console
+$ rustup update
+```
+
+If you don't have it already, you can [get rustup][install] from the appropriate page on our website.

+[install]: https://rustup.rs
+
+## What's new in rustup 1.27.0
+
+This long-awaited Rustup release has gathered all the new features and fixes since April 2023. These changes include improvements in Rustup's maintainability, user experience, compatibility and documentation quality.
+
+Also, it's worth mentioning that Dirkjan Ochtman (djc) and rami3l (rami3l) have joined the team and are coordinating this new release.
+
+At the same time, we have granted Daniel Silverstone (kinnison) and 二手掉包工程师 (hi-rustin) their well-deserved alumni status in this release cycle.
+Kudos for your contributions over the years and your continuous guidance on maintaining the project!
+
+The headlines for this release are:
+
+1. Basic support for the fish shell has been added.
+   If you're using `fish`, PATH configs for your Rustup installation will be added automatically from now on.
+
+   _Please note that this will only take effect on installation, so if you have already installed Rustup on your machine, you will need to reinstall it.
+   For example, if you have installed Rustup via [rustup.rs][install], simply follow [rustup.rs][install]'s instructions again;
+   if you have installed Rustup using [some other method][other installation methods], you might want to reinstall it using that same method._
+
+2. Rustup support for `loongarch64-unknown-linux-gnu` as a _host platform_ has been added.
+   This means you should be able to install Rustup via [rustup.rs][install] and no longer have to rely on [loongnix.cn] or self-compiled installations.
+
+   _Please note that as of March 2024, `loongarch64-unknown-linux-gnu` is a ["tier 2 platform with host tools"], so Rustup is guaranteed to build for this platform.
+   According to Rust's [target tier policy], this does not imply that these builds are also guaranteed to work, but they often work to quite a good degree and patches are always welcome!_
+
+
+Full details are available in the [changelog]!
+
+Rustup's documentation is also available in [the rustup book][book].
