MSEdgeDriver (Chromium) does not work after version 79.0.309.0

问题

I'm using Microsoft Edge Webdriver (Chromium) with Python3 in my script.

The webdriver configuration is as follows:

driveroptions = Options()
driveroptions.add_argument('--inprivate')
driveroptions.add_argument('--disable-infobars')
driveroptions.add_argument('--start-maximized')
driveroptions.add_argument('--auto-open-devtools-for-tabs')
driveroptions.add_argument('--user-data-dir=D:\\Selenium_Edge_Chromium_UserData')
driveroptions.binary_location = "C:\\Users\\Administrator\\AppData\\Local\\Microsoft\\Edge SxS\\Application\\msedge.exe"
# driver = webdriver.Chrome(options=driveroptions, executable_path="msedgedriver.309.exe", service_log_path="D:\\X.txt")
driver = webdriver.Chrome(options=driveroptions, executable_path="msedgedriver.exe", service_log_path="D:\\X.txt")

driver.set_page_load_timeout(40)
wait = WebDriverWait(driver, 40)
driver.get(base_url)

It works well since the 1st time I used Canary, but after version 79.0.309.0 (not included), the driver simply returns the error:

Message: session not created: No matching capabilities found

And the service log here:

I can still use my script if the msedgedriver version is kept at 79.0.309.0.

But what happened to the newer versions of msedgedriver (79.0.313.0, 80.0.315.0 etc.)?

Are they dropping some supported capabilities?

Updated:

Microsoft Edge (Chromium): 80.0.315.0
msedgedriver for Microsoft Edge (Chromium): 80.0.315.0
->
Message: session not created: No matching capabilities found

Microsoft Edge (Chromium): 79.0.313.0
msedgedriver for Microsoft Edge (Chromium): 79.0.313.0
->
Message: session not created: No matching capabilities found

Microsoft Edge (Chromium): 79.0.309.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works well without issue)

and with 79.0.309.0 (and older) msedgedriver:

Microsoft Edge (Chromium): (version before 79.0.309.0)
msedgedriver for Microsoft Edge (Chromium): (version before 79.0.309.0, = browser version)
->
(Works without issue)

Microsoft Edge (Chromium): 79.0.309.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works without issue)

Microsoft Edge (Chromium): 79.0.313.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works without issue)

Microsoft Edge (Chromium): 80.0.315.0
msedgedriver for Microsoft Edge (Chromium): 79.0.309.0
->
(Works without issue)

PS: My GetEdgeDriver.BAT which compares the version of currently installed Microsoft Edge (Chromium) Canary browser with currently downloaded webdriver from https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/. If the latter is lower than the former, it downloads the msedgedriver.exe and overwrites the old one.

I tried the capabilities like below, it worked, you can have a try:

{
    "desiredCapabilities": {
            "nativeEvents": false,
            "browserName": "chrome",
            "version": "",
            "platform": "ANY",
            "javascriptEnabled": true,
            ...
    }
}
