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 This library has been -superseded by the mbedTLS library, which is the current incarnation of -PolarSSL.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.
