# 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.
|
||
|
|
|
||
|
|
## 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 do
|
||
|
|
not 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](https://github.com/curl/curl/pull/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.
