-language or imagery, derogatory comments or personal attacks, trolling, public

3rdparty/curl/libcurl/docs/DEPRECATE.md

-# 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 can't be satisfied properly
-using a work around.
-
-## PolarSSL
-
-The polarssl TLS library has not had an update in over three years. The last
-release was done on [January 7
-2016](https://tls.mbed.org/tech-updates/releases). This library has been
-superseded by the mbedTLS library, which is the current incarnation of
-PolarSSL. curl has supported mbedTLS since 2015.
-
-It seems unlikely that this library is a good choice for users to get proper
-TLS security and support today and at the same time there are plenty of good
-and updated alternatives.
-
-I consider it likely that the existing users of curl + polarssl out there are
-stuck on old curl versions and when they eventually manage to update curl they
-should also be able to update their TLS library.
-
-### State
-
-In the curl 7.65.2 release (July 17, 2019) the ability to build with this TLS
-backend is removed from the configure script. The code remains and can be
-built and used going forward, but it has to be manually enabled in a build (or
-the configure removal reverted).
-
-### Removal
-
-The support for PolarSSL and all code for it will be completely removed from
-the curl code base six months after it ships disabled in configure in a
-release. In the release on or near February 27, 2020. (possibly called curl
-7.70.0).

3rdparty/curl/libcurl/docs/EXPERIMENTAL.md

-# Experimental
-
-Some features and functionality in curl and libcurl are considered
-**EXPERIMENTAL**.
-
-Experimental support in curl means:
-
-1. Experimental features are provided to allow users to try them out and
-   provide feedback on functionality and API etc before they ship and get
-   "carved in stone".
-2. You must enable the feature when invoking configure as otherwise curl will
-   not be built with the feature present.
-3. We strongly advice against using this feature in production.
-4. **We reserve the right to change behavior** of the feature without sticking
-   to our API/ABI rules as we do for regular features, as long as it is marked
-   experimental.
-5. Experimental features are clearly marked so in documentation. Beware.
-
-## Experimental features right now
-
- - HTTP/3 support and options
- - alt-svc support and options
