# 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.

## 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.

## Windows XP

In January 2026, curl drops support for Windows XP and Server 2003. Their
"mainstream support" ended in 2014, with final updates on May 14, 2019.

Making the new minimum target Windows version Vista / Server 2008.
