It should be unrelated to this upgrade, but I ran into some issues while trying to check my DSM/DSMX2 hack RF module. Somehow I lost my models and had to re-enter my eFlite Spitfire in my X9D. This hack RF module, which is in a DM9 case, won't turn on. I checked RF bay pin voltage and saw battery voltage. So I think the module is toast because there is no light, but I have to open it to see if it has an LED. I also have a real DM9 (old DSM protocol only). It's LED turned on and I bound it using PPM, my only choice. I have to dig into the hack's required voltage and pray it is not 3.7V max or something. I'll have to do more research.
Without a true DSM/DSMX2 module protocol, I can't seem to turn off the self leveling by a Channel 7 assigned switch. These are quirks with the Spektrum AR636A receiver installed in this plane. They have a feature of interacting with the TX to assign a new switch for on/off any time you want by holding the joysticks in a certain position. I'm sure OpenTX wouldn't have installed this kind of code.
Edit after trying some things:
My Hack RF Module did bind with the DSM/DMSX choice on the external module, but not the PPM Protocol as two years ago. Again, I didn't expect the upgrades would affect the hack module. The hack module does not have an LED. so I couldn't tell if it was on.
However, I still can't get a switch to function on Channel 7 to effect the flight mode status OFF/Stabilization/Auto-leveling. This worked before my upgrades. Not sure if there is a correlation, has anything to do with my OpenTx upgrade 2.3.11 on an X9D and perhaps an OpenTx bug.
So far, I rebound all the FrSky stuff and most works well, even the S8R's. I set the S8R's only in Quick Mode regardless, and it actually seems more predictable and solid switching from OFF to Stabilization to Auto-leveling more so than the AR636A. The gain adjustment works well and translates to observable changes in servo response.
Edit 05092021:
I installed S8R into a plane. I didn't notice before, but I don't get the temporary blue led when turning on the RX. I calibrated RX using the Lua script. I checked also servos working correct way. I tried invoking the self check by toggling the 3 -pos swiich on Channel 12 and
no blue light. I then tries to press the F/S button on the RX and
again, no blue LED. There was no initial servo movement as expected. I moved functions to extremes and moved the throttle as you should. The control services respond to plane's movement as expected. But I have no idea whether the self-check has worked and the blue light is just not turning on. I see it GitHub that there was a Blue LED light bug reported and supposedly fixed March of 2020. Both of my S8R's were updated and both do not show Blue LED as expected.
Correction: 5/10/2021:
The bug was not fixed. The Self Check Routine is still missing. I wrote issues on GitHub in two areas. OpenTX and FrSkyRC/ Firmware-Test
"I searched for "Blue LED" open or closed issues on OpenTx GitHub and found none.
I wrote this as new issue #8493 on OpenTx GitHub. We'll see how they respond.
"I am a "normal" FrSky User. I updated old X9D Tx and older X9D+ (pre 2019) using Companion 2.3.11. I read about need to update FrSky receiver software to 2.1.x Software. I updated internal module in Tx to XJT 2.1 off the FrSky website. Also updated all my Rx's to the latest 2.1 .x software and specifically for the S8R Rx using SXR_ACCST_2.1.0_FCC.frk.
The update was flashed successfully using the Tx FIRMWARE directory, with firmware loaded on the SD Card and flashed to external device connected to the Rx Smart port.
I bound the Rx using XJT D16, 1-16 Ch and Telemetry On and then used the scripts copied into the SD Card to calibrate the receiver. Calibration successful. (Thumbs up) Using the S8R setup lua script, I chose orientation and enabled both SxR function and Quick Mode. I left all other values alone.
I installed Rx into a plane. I tried the 3-pos switch on Channel 12 to attempt the Self Check routine. The
Blue LED did not come on. I next tried to press the F/S button on the Rx and there was
no Blue LED or servo twitch as I expected. I moved the other joystick function as indicated and then the throttle servo. The plane's functions responded correctly to movement as expected. The assigned Channel 10 switch turns the QM off to Stabilize to Auto-level as expected. The software seems to work, just no confirmation or indication of Self Check routine working and no temporary Blue LED when first turning the Rx on
I have two S8R's and both will not turn Blue LED on. I only get the yellow, red and green lights as expected, green to indicate bind ok.
I reference RCDIY Oscar Liang video for correct setup of an S8R as I know it as a "normal" user.

I don't know if this Blue Light issue is FrSky Rx 2.1.x or Lua Script or OpenTx software related. It just doesn't seem to work as expected.
Kindly, WTS"
Apparently a known bug since June of 2020 and still open. See link below.
Can't trigger self-check procedure by pressing and releasing (F/S) Bind Button as explained in the manual with S8R. Tested with S8R with FW-SxR-v2.1.0_Beta_0529 With S6R it's okay and works...

One minor issue regard general 2.1 updates, one of two X8R receivers doesn't have Channel 1 active for some reason. Either the pin is boke inside or software glitch. I mixed Ail on Channel 5 and it works ok. It's only a 4 channel sport plane. I still have to do range checks.
