+### 2026-03-15 - Deprecating the MINGW64 Environment
+
+As support for Windows 8.1 has been dropped, there is no longer a need for
+non-UCRT environments such as MINGW64. Consequently, we are beginning to phase
+out the MINGW64 environment. To start, no new packages will be added to this
+environment, and existing leaf packages may be removed if issues arise. If you
+are currently relying on the MINGW64 environment, please consider switching to
+UCRT64 or CLANG64 instead.
