+## 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.

-TEST_URL | https://www.google.com | FlareSolverr makes a request on start to make sure the web browser is working. You can change that URL if it is blocked in your country.

 Environment variables are set differently depending on the operating system. Some examples:
-* Docker: Take a look at the Docker section in this document. Environment variables can be set in the `docker-compose.yml` file or in the Docker CLI command.
-* Linux: Run `export LOG_LEVEL=debug` and then start FlareSolverr in the same shell.
-* Windows: Open `cmd.exe`, run `set LOG_LEVEL=debug` and then start FlareSolverr in the same shell.

+## Prometheus exporter
+
+The Prometheus exporter for FlareSolverr is disabled by default. It can be enabled with the environment variable `PROMETHEUS_ENABLED`. If you are using Docker make sure you expose the `PROMETHEUS_PORT`.

+
+```shell

 ## Captcha Solvers
 
-:warning: At this time none of the captcha solvers work. You can check the status in the open issues. Any help is welcome.
+> **Warning**
+> At this time none of the captcha solvers work. You can check the status in the open issues. Any help is welcome.
 
 Sometimes CloudFlare not only gives mathematical computations and browser tests, sometimes they also require the user to
 solve a captcha.
 If this is the case, FlareSolverr will return the error `Captcha detected but no automatic solver is configured.`
 
-FlareSolverr can be customized to solve the captchas automatically by setting the environment variable `CAPTCHA_SOLVER`
-to the file name of one of the adapters inside the [/captcha](src/captcha) directory.

+
+        desired_capabilities: dict, optional, default: None - auto from config
+            Dictionary object with non-browser specific capabilities only, such as "item" or "loggingPref".
+
+        advanced_elements:  bool, optional, default: False
+            makes it easier to recognize elements like you know them from html/browser inspection, especially when working
+            in an interactive environment
+
+            default webelement repr:
+            <selenium.webdriver.remote.webelement.WebElement (session="85ff0f671512fa535630e71ee951b1f2", element="6357cb55-92c3-4c0f-9416-b174f9c1b8c4")>

+
+            note: when retrieving large amounts of elements ( example: find_elements_by_tag("*") ) and print them, it does take a little more time.
+
+
+        service_log_path: str, optional, default: None
+             path to log information from the driver.
+
+        keep_alive: bool, optional, default: True
+             Whether to configure ChromeRemoteConnection to use HTTP keep-alive.
+
+        log_level: int, optional, default: adapts to python global log level
+
+        headless: bool, optional, default: False
+            can also be specified in the options instance.
+            Specify whether you want to use the browser in headless mode.
+            warning: this lowers undetectability and not fully supported.
+
+        version_main: int, optional, default: None (=auto)
+            if you, for god knows whatever reason, use
+            an older version of Chrome. You can specify it's full rounded version number
+            here. Example: 87 for all versions of 87
+
+        patcher_force_close: bool, optional, default: False
+            instructs the patcher to do whatever it can to access the chromedriver binary
+            if the file is locked, it will force shutdown all instances.
+            setting it is not recommended, unless you know the implications and think
+            you might need it.
+
+        suppress_welcome: bool, optional , default: True
+            a "welcome" alert might show up on *nix-like systems asking whether you want to set
+            chrome as your default browser, and if you want to send even more data to google.
+            now, in case you are nag-fetishist, or a diagnostics data feeder to google, you can set this to False.
+            Note: if you don't handle the nag screen in time, the browser loses it's connection and throws an Exception.
+
+        use_subprocess: bool, optional , default: True,
+
+            False (the default) makes sure Chrome will get it's own process (so no subprocess of chromedriver.exe or python
+                This fixes a LOT of issues, like multithreaded run, but mst importantly. shutting corectly after
+                program exits or using .quit()
+                you should be knowing what you're doing, and know how python works.
+
+              unfortunately, there  is always an edge case in which one would like to write an single script with the only contents being:
+              --start script--
+              import undetected_chromedriver as uc
+              d = uc.Chrome()
+              d.get('https://somesite/')
+              ---end script --
+
+              and will be greeted with an error, since the program exists before chrome has a change to launch.
+              in that case you can set this to `True`. The browser will start via subprocess, and will keep running most of times.
+              ! setting it to True comes with NO support when being detected. !
+
+        no_sandbox: bool, optional, default=True
+             uses the --no-sandbox option, and additionally does suppress the "unsecure option" status bar
+             this option has a default of True since many people seem to run this as root (....) , and chrome does not start
+             when running as root without using --no-sandbox flag.
+
+        user_multi_procs:
+            set to true when you are using multithreads/multiprocessing
+            ensures not all processes are trying to modify a binary which is in use by another.
+            for this to work. YOU MUST HAVE AT LEAST 1 UNDETECTED_CHROMEDRIVER BINARY IN YOUR ROAMING DATA FOLDER.
+            this requirement can be easily satisfied, by just running this program "normal" and close/kill it.
