+# 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.
+
+## 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.
+
+Previous discussion and details: https://github.com/curl/curl/discussions/15972
+
+## 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.
+
+## c-ares 1.16.0
+
+In March 2026, we drop support for all c-ares versions before 1.16.0.
+
+## OpenSSL 1.0.2
+
+OpenSSL and others only ship fixes for this version to paying customers,
+meaning users of the free version risk being vulnerable.
+
+We remove support for this OpenSSL version from curl in December 2025.
+
+## OpenSSL 1.1.1
+
+OpenSSL and others only ship fixes to paying customers, meaning users of the
+free version risk being vulnerable.
+
+We remove support for this OpenSSL version from curl in December 2025.
+
+## OpenSSL-QUIC
+
+OpenSSL-QUIC is what we call the curl QUIC backend that uses the OpenSSL QUIC
+stack.
+
+ - It is slower and uses more memory than the alternatives and is only
+   experimental in curl.
+ - It gets little attention from OpenSSL and we have no expectation of the
+   major flaws getting corrected anytime soon.
+ - No one has spoken up for keeping it
+ - curl users building with vanilla OpenSSL can still use QUIC through the
+   means of ngtcp2
+
+We remove the OpenSSL-QUIC backend in March 2026.
