missing commits/fixes in 1.8.4

The 1.8.4 version has just been released but some commits/patches have disappeared between 1.8.4-rc3 and 1.8.4-rc4.
A new 1.8.4 branch was created https://github.com/influxdata/influxdb/tree/1.8.4
whereas some fixes were provided in a 1.8 branch till 1.8.4-rc3 : https://github.com/influxdata/influxdb/tree/1.8

Also, the release note claims the 1.8.3 version was not released, which is not the case :
https://github.com/influxdata/influxdb/releases/tag/v1.8.4
https://www.influxdata.com/blog/release-announcement-influxdb-oss-2-0-3/

What happened to this 1.8.4 release ?

Compare the 1.8 and 1.8.4 branch histories from 1.8.4-rc3 through 1.8.4-rc4, then review the linked v1.8.4 release notes and announcement. Document which commits or fixes are missing and reconcile the claim about the 1.8.3 release; completion requires an agreed explanation or corrected release information.
