v2.0.0 (2021/10/20)

FlareSolverr 2.0.0 is out with some important changes:

It is capable of solving the automatic challenges of Cloudflare. CAPTCHAs (hCaptcha) cannot be resolved and the old solvers have been removed.
The Chrome browser has been replaced by Firefox. This has caused some functionality to be removed. Parameters: userAgent, headers, rawHtml and downloadare no longer available.
Included proxy support without user/password credentials. If you are writing your own integration with FlareSolverr, make sure your client uses the same User-Agent header and Proxy that FlareSolverr uses. Those values together with the Cookie are checked and detected by Cloudflare.
FlareSolverr has been rewritten from scratch. From now on it should be easier to maintain and test.
If you are using Jackett make sure you have version v0.18.1041 or higher. FlareSolverSharp v2.0.0 is out too.
