+
+# Migration to `webkit2gtk-4.1` on Linux port
+
+Hello everybody! We just released [Tauri v2.0.0-alpha3](https://github.com/tauri-apps/tauri/releases/tag/tauri-v2.0.0-alpha.3) recently. While it doesn't bring any major feature, it does bring some huge impacts on Linux port.
+We will use [WebKit2GTK–4.1](https://webkitgtk.org/reference/webkit2gtk/stable/index.html) in 2.0 from now on.
+
+<!--truncate-->
+
+## What does this mean?
+
+If you are using Tauri version 1.x, there's nothing to worry about. Everything you need is still the same.
+But if you are using Tauri version 2.0 alpha version starting from `alpha.3`, you will need to install the new WebKit2GTK package with API version 4.1.
+We will update the prerequisites in our site soon. But if you want to know how to install such version, here are some instructions from [wry](https://github.com/tauri-apps/wry#linux):
+
+```bash
+# On Arch Linux / Manjaro:
+sudo pacman -S webkit2gtk-4.1
+# On Debian / Ubuntu:
+sudo apt install libwebkit2gtk-4.1-dev
+# On Fedora:
+sudo dnf install webkit2gtk4.1-devel
+```
+
+## Will this bring breaking changes to my code?
+
+The main difference between version 4.0 and 4.1 are the soup library. WebKit2GTK-4.0 uses soup2 and WebKit2GTK-4.1 uses soup3.
+So if you didn't use any soup2-specific APIs, your applications should continue to work fine.
+
+The reason behind this change is because we aim to add flatpak support, but [Gnome runtime](https://docs.flatpak.org/en/latest/available-runtimes.html#gnome) uses webkit2gtk-4.1.
+There are also some subtle bugs like [this](https://github.com/tauri-apps/wry/issues/717) that only happen in soup2 and they can be fixed by upgrading to soup3.
+
+## What other breaking changes we are going to expect?
+
+The major one will be the MSRV. With Tauri v2.0.0-alpha.3 released, MSRV is bumped to 1.64. We will also update windows-rs in the future.
+This Rust version should satisfy the latest version of windows-rs.
+We do plan to update our MSRV with minor releases after 2.0. This could ease the friction to stick to any fixed Rust version while updating dependencies.
