Bump db_version to 8.0

[ironprogrammer]

What is this?

WordPress's minimum MySQL version was recently bumped to 5.5.5, which means this plugin no longer works with WordPress trunk. Let's bump the reported DB version to 8.0 to make it last a while.

Version bump was done here:
WordPress/wordpress-develop@e1265a3

Also see this for a similar change:
WordPress/sqlite-database-integration@768f8cc

Why do this?

Even though there is a canonical plugin furthering this work, this dropin remains an easy, scriptable way to use SQLite on a new WordPress install without a MySQL server requirement.

With 6.5 out in production now - any information on getting this merged?

It would be nice to have it merged, it's a pain to manually change the content of db.php every time.

Same here.

Can confirm that this solves the issue when running wp-pest on WP 6.5+ Can we merge it? I have a fork where I've added .gitattributes file and updated the test matrix a bit, so I can also make a PR with the improvements, but only if it will be merged.

@aaemnnosttv any words on if you'll be able to merge this?

Thanks for the PR @ironprogrammer and apologies for the delay on this. I just (unknowingly) released https://github.com/aaemnnosttv/wp-sqlite-db/releases/tag/v1.3.2 which bumps this to 5.5.5 but I'm happy to update it for consistency with the core integration 👍
