Why does MySQL leap from version 5.7 to 8.0?

I recently upgraded MySQL 5.7 to 8.0 via homebrew, as it warned me about not being the latest version. I was surprised to see MySQL was version 8.0 as from what I recall the latest version was 5.7. Then I found out there are no 6 and 7 versions which also seems a bit odd.

I struggle to find any relevant or official explanation regarding why it sees this gigantic leap to version 8.0 and skipping right over 6 and 7. While it may be just a convention, this myopic version management only confuses users without any reason why when needing some simple clarification.

So why does the MySQL version numbers see such a leap and skip over 6 and 7?

Solution 1:

MySQL 5.7 to 8.0 Skipping 6 and 7

Official Oracle answer per MySQL 8.0 FAQ: General. . .

Why did MySQL version numbering skip versions 6 and 7 and go straight to 8.0?

"Due to the many new and important features we were introducing in this MySQL version, we decided to start a fresh new series. As the series numbers 6 and 7 had actually been used before by MySQL, we went to 8.0."

For the people that wonder what's up with the bogus MySQL 6.0 that was once announced. . .
