+# Items to be removed from future curl releases
+
+If any of these deprecated features is a cause for concern for you, please
+email the
+[curl-library mailing list](https://lists.haxx.se/listinfo/curl-library)
+as soon as possible and explain to us why this is a problem for you and
+how your use case cannot be satisfied properly using a workaround.
+
+## Nothing
+
+Nothing is currently scheduled to be removed.
+
+## msh3 support
+
+The msh3 backed for QUIC and HTTP/3 was introduced in April 2022 but has never
+been made to work properly. It has seen no visible traction or developer
+activity from the msh3 main author (or anyone else seemingly interested) in
+two years. As a non-functional backend, it only adds friction and "weight" to
+the development and maintenance.
+
+Meanwhile, we have a fully working backend in the ngtcp2 one and we have two
+fully working backends in OpenSSL-QUIC and quiche well on their way of ending
+their experimental status in a future.
+
+We remove msh3 support from the curl source tree in July 2025.
+
+## winbuild build system
+
+curl drops support for the winbuild build method after September 2025.
+
+We recommend migrating to CMake. See the migration guide in
+`docs/INSTALL-CMAKE.md`.
+
+## Windows CE
+
+Windows CE "mainstream support" ended on October 9, 2018, and "Extended
+Support" ended on October 10, 2023.
+
+curl drops all support in November 2025.
+
+## VS2008
+
+curl drops support for getting built with Microsoft Visual Studio 2008 in
+November 2025.
+
+The only reason we kept support for this version is for Windows CE - and we
+intend to remove support for that Operating System in this time frame as well.
+Bumping the minimum to VS2010. VS2008 is a pain to support.
