WordPress 4.9.8 Release Candidate 1

The release candidate package for 4.9.8 has been released and is now available for testing. Please help test the release candidate version to ensure the version works as expected.

Note: testing of the release candidate package shortly after it was built uncovered a serious bug in the “Try Gutenberg callout”, see #44635.  It was decided that we should still go forward with the release and will release a 2nd release candidate package as soon as a fix for this bug is found.

The total number of bug fixes in 4.9.8 is 28, the number of enhancements remains is 12 and the number of blessed tasks is 3.
 
The official 4.9.8 release is scheduled for Tuesday, July 31st.
