WordPress 4.9.5 Release Candidate

WordPress 4.9.5 maintenance release is scheduled for April 3rd.

The release candidate package is now ready for testing. Please help us by testing this release to ensure 4.9.5 fixes the reported issues and doesn’t introduce any new ones. This beta release contains 25 fixes and improvements.

Please note: the Try Gutenberg callout will ultimately not land in 4.9.5 release. There are still a few issues that need to get fixed before it's ready for the level of attention this will bring. It will probably land in a dedicated 4.9.6 release in a few weeks (also see related trac ticket: #41316)
