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 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.
NTLM_WB auth
This NTLM authentication method is powered by a separate tool,
ntlm_auth. Barely anyone uses this method. It was always a quirky
implementation (including fork + exec), it has limited portability and we
don't test it in the test suite and CI.
We keep the native NTLM implementation.
Due to a mistake, the NTLM_WB functionality is missing in builds since 8.4.0
(October 2023). It needs to be manually patched to work. See PR
12479.
curl will remove the support for NTLM_WB auth in April 2024.
space-separated NOPROXY patterns
When specifying patterns/domain names for curl that should not go through a
proxy, the curl tool features the --noproxy command line option and the
library supports the NO_PROXY environment variable and the CURLOPT_NOPROXY
libcurl option.
They all set the same list of patterns. This list is documented to be a set of comma-separated names, but can also be provided separated with just space. The ability to just use spaces for this has never been documented but some users may still have come to rely on this.
Several other tools and utilities also parse the NO_PROXY environment
variable but do not consider a space to be a valid separator. Using spaces for
separator is probably less portable and might cause more friction than commas
do. Users should use commas for this for greater portability.
curl will remove the support for space-separated names in July 2024.
