1.) Since you are using SVN 1.11.0, an SVN checkout from GitHub is no longer possible and errors with unsupported WebDAV protocol:
Can't create session
Unable to connect to repository at URL
[any HTTPS based SVN URL]
RA layer didn't receive requested OPTIONS info
The server at
[any HTTPS based SVN URL] does
not support the HTTP/DAV protocol.
This seems to be a bug in SVN, but it is nasty as the user cannot switch to an old SVN executable (1.10.x) which is working OK.
Seems to be a known error, e.g. see here:
https://svn.haxx.se/users/archive-2018-11/0026.shtml
2.) I don't find the nest in system tray option anymore. Is it gone? If so, why? Starting up SmartSVN is time-consuming compared to having it nested in the tray.
I hope you can help me.
Yes, it looks like that. Unfortunately its not working for any Github repo used through the SVN interface. But it seems you do everything compliant to Subversion.
Please allow me two more questions:
1.) I assume its not possible for the user to spcify a svn executable (I've seen similar in SmartGIT)?
