# 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.

|
|
|
## 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.
