 - Ruby default version has been updated from 3.3 to 3.4.
   Refer to the [upstream release announcement](https://www.ruby-lang.org/en/news/2024/12/25/ruby-3-4-0-released/) for details.
 
+- []{#x86_64-darwin-26.05}
+
+  **This will be the last release of Nixpkgs to support `x86_64-darwin`.**
+  Platform support will be maintained and binaries built until Nixpkgs 26.05 goes out of support at the end of 2026.
+  For 26.11, due to Apple’s deprecation of the platform and limited build infrastructure and developer time, we will no longer build packages for `x86_64-darwin` or support building them from source.
+
+  By the time of 26.11’s release, Homebrew will offer only limited [Tier 3](https://docs.brew.sh/Support-Tiers#tier-3) support for the platform, but MacPorts will likely continue to support it for a long time.
+  We also recommend users consider installing NixOS, which should continue to run on essentially all Intel Macs, especially after Apple stops security support for macOS 26 in 2028.
+
+  A warning will be displayed for `x86_64-darwin` users; you can set [](#opt-allowDeprecatedx86_64Darwin) in the [Nixpkgs configuration](https://nixos.org/manual/nixpkgs/stable/#chap-packageconfig) to silence it.
+  The {file}`~/.config/nixpkgs/config.nix` file will not work for users of flakes, who can instead replace `nixpkgs.legacyPackages.x86_64-darwin` with
+
+  ```nix
+  import nixpkgs {
+    system = "x86_64-darwin";
+    config.allowDeprecatedx86_64Darwin = true;
+  }
+  ```
+
+  nix-darwin users can set [`nixpkgs.config.allowDeprecatedx86_64Darwin`](https://nix-darwin.github.io/nix-darwin/manual/index.html#opt-nixpkgs.config) in their system configurations.
+
 - The Factor programming language has been updated to Version 0.101 bringing various improvements to UI rendering and HiDPI support as well as support for Unicode 17.0.0.
   Starting from Version 0.100, the Factor VM is compiled with Clang.
