MySQL upgrade version output seems odd
Short answer:  Not to worry.
Long answer:
I did a survey of over 200 MySQL and MariaDB version names -- 40% ended with -log.  They went back to version 4.1, perhaps farther.
(Interestingly, none of the 8.0 versions ended in -log.)
(I've been using MySQL for 20 years, and have never heard why some have &quot;-log&quot;.  And I have not noticed a problem.)
For more trivia:
SHOW VARIABLES LIKE 'version%';
