I dunno about holes, but…

SQLite has gone into a frenzy of bug fixing this past year, changing long stable processes to ease things up: opening a specific report channel just for these kinds of bugs, adding features to Fossil to help manage things on their end (and that's just the visible stuff).

And with all that, the latest release has unfortunately been the buggiest I've experienced so far.

I skipped the .0 because of a crash, and only released .1 after giving up waiting for a .2 that never came, with a patch to fix a serious performance regression.

I spent a month supposedly shipping old bugs no one had a problem with, rather than shipping new bugs that instantly crashed things or caused measurable regressions.

That's on a software with stellar testing, and a good engineering team known to favour stability over the new shiny.
