 - The default GHC version has been updated from 9.8 to 9.10.
   `haskellPackages` correspondingly uses Stackage LTS 24 (instead of LTS 23) as a baseline.
 
-- Darwin has switched to using the system libc++. This was done for improved compatibility and to avoid ODR violations.
-  If a newer C++ library feature is not available on the default deployment target, you will need to increase the deployment target.

 - **This release of Nixpkgs requires macOS Sonoma 14.0 or newer, as announced in the 25.05 release notes.**
   The default SDK is now 14.4, but the minimum version is 14.0.
   cc-wrapper will enforce that availability annotations are used or an appropriate deployment target is set.
   See the Darwin platform notes for details.
 
+- **We expect to drop support for `x86_64-darwin` by Nixpkgs 26.11,** in light of Apple’s announcement that macOS 26 will be the final version to support Intel Macs.
+  When support is fully removed, we will no longer build packages for the platform or guarantee that it can build at all.
+  This may happen in stages, depending on our available build and maintenance resources and decisions made by projects we rely on.
+
+  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.
