Seafile community edition 8.0 is ready for test!

@daniel.pan can we move/merge/mention
8.0.2: password protected Upload link and
https://forum.seafile.com/t/two-factor-auth-is-enabled-no-access-to-webdav/
here? Both are things affecting 8.0.x breaking behavior when comparing to 7.x

While the upload link thing seems to be a bug, the webdav/2FA change is still not mentioned anywhere than this thread: Disable webdav for users that have 2fa enabled
I guess it affects a lot more installations. While I get the reasoning behind it, I’m glad I knew before upgrading (by reading it by chance) so we can get our stuff in order first. Please add it to your changelog.
