-### Requirements ###
+### Launching WSL ###
 
-Wsltty does not seem to work with WSL V2 mode since release 2.0.0 (#343).
+Since wsltty 3.8.0, mintty launches WSL using the native Windows launcher 
-As a workaround until a solution in the wslbridge gateway, it is suggested 
+gateway `wsl.exe`. Previously, this approach used to fail due to two problems:
-to install [release 1.3.17](https://github.com/microsoft/WSL/releases/tag/1.3.17); 
+* The wslbridge approach would fail in notoriously frequent cases 
-maybe uninstall WSL first, see [issue 343 comment](https://github.com/mintty/wsltty/issues/343#issuecomment-1818367512).
+  due to its need to use undocumented Windows APIs.
-Another remedy could be to configure your WSL distributions to run in WSL V1 mode, for example:
+* Using `wsl.exe` directly, the _conhost_ layer hooked into the 
-`wsl --set-version Ubuntu 1`.
+  workflow used to obstruct transparent terminal operation in multiple ways.
+
+The _conhost_ layer has meanwhile been modernised and its enforced detour 
+through the Windows console API has been dropped, in the course of the 
+Windows Terminal project. The new _conhost_, however, has not yet been 
+deployed with Windows (as of summer 2025) and will probably not be 
+deployed with Windows 10 anymore. So in order to get fully transparent 
+terminal interaction between WSL and wsltty, the updated _conhost_ needs 
+to be patched into Windows manually, following the instructions in the 
+[mintty wiki, section Interaction with WSL](https://github.com/mintty/mintty/wiki/Tips#interaction-with-wsl-and-other-windows-programs) 
+to patch OpenConsole into your Windows as conhost replacement.
+
+#### Troubleshooting display corruption ####
+
+With the new conhost/conpty layer unfortunately display appears broken 
+in certain cases. Two workarounds are available, both setting an option 
+in a config file (%APPDATA%/wsltty/config):
+* `Baud=999999`
+
+or
+* `WSLbridge=2`.
+
+The latter switches back to the wslbridge launching approach; the 
+wslbridge2 gateway is still deployed with wsltty for that matter. 
+(If for a very old Windows 10 version you still need the original 
+wslbridge gateway, set `WSLbridge=1` and deploy it manually.)
+
+#### WSL bridge requirements in previous releases ####
+
+To connect to WSL, wsltty used wslbridge2, which uses undocumented 
+Windows APIs that have been changed various times, so wslbridge2 needed 
+to catch up with incompatible changes, particularly to support WSL V2.
+(See e.g. issue #343; to work with WSL V2, wsltty 2.0.0 needed a WSL update 
+to [release 1.3.17](https://github.com/microsoft/WSL/releases/tag/1.3.17).)
 
 Since release 3.0.5, WSLtty requires Windows version 1809 (the November 2018 release).
 
+By end of 2024, wsltty works again with recent updates of the WSL subsystem.
