Please release LND v0.18.4 that includes the fix, and provide precompiled binaries urgently

Thanks, it worked, but I think they should release the final fix by releasing LND v0.18.4

See #9053

As suggested above, you should set the deprecatedrpc=warnings config flag if you want to run with the latest version of bitcoind.

Why did you not release the LND v0.18.4 with the fix yet? Why is it not considered a problem of considerable urgency to be solved with precompiled binaries that include the hotfix if right now there is no compatibility between Bitcoin Core and LND without touching anything?

It is still not solved after more than a month.
The change in bitcoin.conf is only a workaround.
I don't like how the LND Developers ignowre it's users.

• Nobody is being ignored. The fix was merged, just not released yet. Bundling a release is a lot of effort. And the upcoming (ETA for an RC this week) v0.18.4 will have way more than just this single bug fix.
• lnd doesn't promise to be forward-compatible. normally that's not an issue, but:
• bitcoind broke one of its APIs. Meaning it no longer is backward compatible without the flag. Why do we get all the slack for that?
• There is a low-effort workaround available. Which further takes merit away from derailing an already parallel running version release cycle due to a single fix.
