Are there any versions of Syncthing that support both old and recent TLS? I have some devices that cannot (with reasonable effort) be upgraded to newest syncthing. Having at least some clients using versions that talk to both worlds (and act as bridges) would be nice.

You can still use TLS 1.2 in the newest versions with the `insecureAllowOldTLSVersions` option enabled. Please check [https://docs.syncthing.net/advanced/option-insecure-allow-old-tls-versions.html](https://docs.syncthing.net/advanced/option-insecure-allow-old-tls-versions.html).

Thanks… Is it also on Android? Failed to find a menu item. How do folks usually edit those?

Yep, you can access the Web GUI from the left slideout menu there. Then you will be able to use the exact same interface as you do in a browser.
