Description:
From the github, it appears that 

Bug#32843447: GTID_PURGED IS GETTING EMPTY AND GTID_EXECUTED
                  IS GETTING UPDATED AFTER RESTARTING MYSQL

is fixed only in 5.7 version and it is null merged to 8.0 (problem is not required in 8.0 version)

But 8.0.27 is mentioning this bug in release notes.  

https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-27.html

Also 8.0 mysqldump document talks about skip-mysql-schema option https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html#option_mysqldump_skip-mysql-schema
which does not exists in 8.0.27 (it exists only in 5.7.36). 

How to repeat:
Please see 

1) https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-27.html
2) https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html#option_mysqldump_skip-mysql-schema
3) Please see github code  https://github.com/mysql/mysql-server/blob/8.0/client/mysqldump.cc (it does not contain skip-mysql-schema option like it exists in 5.7 code 
https://github.com/mysql/mysql-server/blob/5.7/client/mysqldump.c#L527

Suggested fix:
Please fix release notes and documentation to avoid confusion.
