+# 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+superseded by the mbedTLS library, which is the current incarnation of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).
