Dear XRootD community,
The first RC for 5.0.0 has been tagged hence I'm creating this issue so we have a place where we can discuss the upcoming MAJOR release.
Here is the link to tentative release notes:
https://github.com/xrootd/xrootd/blob/stable-5.0.x/docs/ReleaseNotes.txt
Please NOTE: this is a rough approximation of the actual release 5.0.0 meant for testing! That said, we STRONGLY ENCOURAGE you to test it!
Please NOTE: as this is a major release it is a unique opportunity to break ABI and hence if you have any request which needs breaking current (4.x.x) ABI please speak up!
Please NOTE: we especially encourage you to test the newly implemented TLS support, all the details on how to configure encryption on the server side can be found in:
https://xrootd.slac.stanford.edu/doc/dev50/xrd_config.htm#_Toc22335919
